Retirement Income Calculator: $29,750 vs $56,000 Expenses at 65
Use this guide to understand the assumptions, inputs, results, and next steps behind the calculator.

Retirement income is the money available to pay for expenses after work, including Social Security, pension payments, investment withdrawals, part-time work, rental income, and other recurring sources. This calculator projects income and expenses by age, estimates after-tax income, tracks portfolio withdrawals, and shows when the modeled savings balance may run out.
The default example projects a household from age 65 through age 90. It assumes $500,000 in retirement savings, a 4% withdrawal rate, $15,000 in annual part-time income until age 70, and Social Security beginning at age 67 for both people. It also assumes $36,000 in essential expenses, $12,000 in discretionary spending, $8,000 in healthcare costs, 2.5% general inflation, 5% investment return, a 2.5% Social Security cost-of-living adjustment (COLA), a 15% flat tax estimate, and 5% healthcare inflation.
The default result is a useful stress test, not a prediction: first-year after-tax income is $29,750, first-year expenses are $56,000, expense coverage is 53%, and savings are projected to last until age 88. The projection assumes a smooth annual return, a simplified tax rate, and the income and expense assumptions you enter. Test alternative scenarios before making a retirement-date decision.
How To Use The Income Projection
Enter your timeline, income sources, expenses, and financial assumptions in separate steps.
- Set current age, retirement age, and life expectancy. The projection begins at the later of current age or retirement age. The years modeled equal life expectancy minus that starting age.
- Add Social Security for each person. Enter the monthly benefit and the age it is expected to start. Use an estimate from the Social Security Administration rather than a wage-based guess; its retirement estimator uses your earnings record.
- Enter pension and other income. Add pension income and its starting age, part-time work and its end age, rental income, and other recurring income. Related comparisons include the pension income calculator, rental income calculator, and dividend income projection.
- Enter savings and withdrawal rate. The model uses a percentage of starting retirement savings to set an annual withdrawal amount. A separate retirement withdrawal calculator can help inspect withdrawal amounts.
- Set expenses and assumptions. Enter essential expenses, discretionary expenses, and healthcare costs. Then set inflation, investment return, Social Security COLA, estimated tax rate, and healthcare inflation.
Include costs you expect to pay from retirement income. If your healthcare cost field already includes premiums and out-of-pocket expenses, do not also count the same costs in essential expenses. Use a retirement budget guide to organize categories and avoid omissions.
What The Default Results Show
At age 65, the default inputs have not yet reached either person’s Social Security start age of 67. The calculator therefore shows no Social Security in the first projected year. Pension income is also zero because the pension input is $0. The household’s first-year modeled income comes from the $20,000 savings withdrawal and $15,000 part-time income.
The withdrawal calculation is:
Annual savings withdrawal
= starting retirement savings × withdrawal rate
= $500,000 × 4%
= $20,000
The calculator adds the $20,000 withdrawal to $15,000 in part-time income to get $35,000 before its tax estimate. It then applies the entered 15% tax rate:
Tax estimate
= $35,000 × 15%
= $5,250
First-year after-tax income
= $35,000 − $5,250
= $29,750
First-year expenses are $36,000 essential + $12,000 discretionary + $8,000 healthcare = $56,000. The first-year shortfall is:
Income minus expenses
= $29,750 − $56,000
= −$26,250
So the default expense coverage result is $29,750 ÷ $56,000 = about 53%. The calculator reports the income as after-tax but compares it with the entered expense total; the expense inputs are not separately grossed up for taxes.
By age 67, both Social Security benefits have started. The two monthly inputs total $3,300, or $3,300 × 12 = $39,600 per year before the COLA assumption. Part-time work continues only until age 70 under the defaults. These timing changes mean that the first-year snapshot does not represent every retirement year.
In the final projected year, age 90, the default output shows income of $62,404, expenses of $116,080, and a $53,676 shortfall. The projection’s lifetime income is $1,731,955.60, lifetime expenses are $2,137,470, and savings are projected to run out at age 88. The cumulative shortfall is not the same as a precise amount you must save today; the timing of cash flows, returns, taxes, and inflation matters.
| Scenario | Social Security start | Part-time income | Annual withdrawal assumption | What changes in the model |
|---|---|---|---|---|
| Earlier benefit timing | 65 | $15,000 through 70 | 4% of $500,000 = $20,000 | Social Security starts two years earlier than the default |
| Default timing | 67 | $15,000 through 70 | 4% of $500,000 = $20,000 | Both Social Security inputs start at 67 |
| Later benefit timing | 70 | $15,000 through 70 | 4% of $500,000 = $20,000 | The gap before benefits is longer; later benefits may be higher |
| Lower withdrawal rate | 67 | $15,000 through 70 | 3% of $500,000 = $15,000 | Annual portfolio withdrawal falls by $5,000 |
The table isolates input changes rather than predicting a replacement result card. Social Security claiming decisions depend on household circumstances, benefit estimates, work history, health, and longevity. Test the implications with an official estimate and review the monthly retirement income calculator.
How Income Sources Are Treated
Social Security And COLA
The calculator starts each Social Security benefit at the age you enter. It multiplies the monthly amount by 12 and applies the COLA assumption annually in the projection. Social Security’s actual cost-of-living adjustment is set under federal rules and may differ from your planning input. The Social Security Administration explains how COLAs are determined.
A benefit estimate is not always the amount a person will receive at every claiming age. Your age when benefits begin can affect the monthly amount, and household rules can affect spousal or survivor benefits. The calculator accepts the amounts you provide; it does not derive a personalized claiming strategy. Compare a claiming scenario with the Social Security leveling calculator if relevant, and read what counts as good retirement income.
The 2026 maximum Social Security retirement benefit at full retirement age is about $4,018 per month for an eligible worker, but most people receive less. A maximum benefit is not a useful default for every household. Use a personal estimate based on your earnings history.
Pension, Work, Rent, And Other Income
Pension income begins at the age entered and receives the modeled COLA. If your pension has no inflation adjustment, enter a COLA assumption that reflects that feature rather than automatically matching general inflation. For more detail on payment options, compare the pension income calculator.
Part-time income is assumed to continue until the entered end age and rises with general inflation. Rental and other income also rise with general inflation in this projection. The calculator does not subtract property expenses, vacancy, repairs, or rental taxes from gross rent. Use a net income estimate or model property costs separately. Airbnb or short-term rental income may need a different expense treatment; see the Airbnb retirement income calculator.
Savings Withdrawals And Portfolio Balance
The annual withdrawal is set from the initial retirement savings multiplied by the selected withdrawal rate. In the provided computation, that annual amount is based on the starting balance, not a new percentage of the current balance each year. The portfolio balance then changes as withdrawals and assumed investment growth are applied.
A 4% input is not a guarantee that a portfolio will support 4% withdrawals for every retirement length or market path. The rule of thumb associated with a 4% initial withdrawal is not a personalized safe rate. A safe withdrawal rate comparison can test alternative rates, and a bear-market impact estimate can illustrate the risk of poor returns early in retirement.
Some retirement accounts have required minimum distributions (RMDs), which are tax rules rather than a spending recommendation. Under current federal law, the general RMD starting age is 73, rising to 75 in 2033 under SECURE 2.0 for people subject to the later age. This calculator does not determine your required distribution. Check IRS rules and your account type before setting withdrawals.
Expenses, Inflation, And Taxes
Essential expenses are entered as an annual amount and grow with general inflation. Discretionary expenses are also increased by general inflation. Healthcare costs use the separate healthcare inflation rate. In the default inputs, healthcare inflation is 5%, twice the 2.5% general inflation assumption, so healthcare becomes a larger share of modeled expenses over time.
The first-year default expenses are $56,000, but future expenses rise. At age 90, the result is $116,080. That total is driven by the selected assumptions and the model’s year-by-year inflation calculations. A separate healthcare cost projection can help you investigate medical spending, while a healthcare inflation calculator can help test its growth rate.
The calculator uses a flat 15% tax-rate assumption. It does not calculate federal tax brackets, state income tax, tax-free Roth withdrawals, qualified dividends, deductions, or the taxable portion of Social Security. Actual taxes depend on income sources, filing status, account type, and tax law. The IRS explains the rules for taxation of Social Security benefits and retirement plan distributions.
Because the calculator applies one rate to modeled income, its after-tax result is a planning approximation—not a tax return estimate. For account sequencing, compare a tax-efficient withdrawal strategy and review how retirement account withdrawals are taxed.
Formula: Annual Cash Flow And Coverage
The projection combines sources that are active at each age, applies its tax assumption, and compares income with expenses.
Annual savings withdrawal
= starting retirement savings × withdrawal rate
Pre-tax annual income
= Social Security + spouse Social Security + pension
+ savings withdrawal + part-time work + rental income + other income
Estimated after-tax income
= pre-tax annual income × (1 − estimated tax rate)
Expense coverage
= estimated after-tax income ÷ total annual expenses × 100
Expenses are modeled separately:
Total annual expenses
= essential expenses × general inflation factor
+ discretionary expenses × general inflation factor
+ healthcare costs × healthcare inflation factor
The exact year-by-year balance calculation depends on the implementation’s cash-flow sequence. Read the result table as a scenario projection, and use the provided age-by-age income, expenses, and balance columns to see when the plan’s pressure is greatest.
Interpreting The Result Cards And Table
Year 1 After-Tax Income
This is the model’s first projected year of income after its flat tax estimate. It is affected by benefit start ages, part-time work, pension commencement, and withdrawals. If you retire before Social Security begins, the first few years can look very different from later years.
Year 1 Expenses
This adds the entered essential, discretionary, and healthcare expenses for the first projection year. It does not automatically know that a cost is missing or already included elsewhere. Check for double counting, especially for health premiums, property costs, and taxes.
Expense Coverage
Coverage is the ratio of after-tax income to modeled expenses. A result below 100% indicates the first-year expenses exceed modeled after-tax income; the gap may be funded from assets or require a change in spending or income. It does not mean you must cut spending by exactly that percentage, because the calculator also projects portfolio withdrawals and changing income over time.
Savings Last Until
This is the age at which the modeled savings balance is exhausted, or the life-expectancy age if it remains positive through the projection. The default result is age 88, two years before the age-90 endpoint. It does not mean all income stops at 88; Social Security and other income may continue, but the portfolio funding modeled by the calculator has run out.
The table’s “Savings” column shows withdrawals, while “Income” combines income sources. Its “+/−” column shows the difference between income and expenses. Review the full series rather than relying only on the first-year cards.
What To Do If The Projection Shows A Gap
A gap is a signal to test alternatives, not a verdict. Explore the options one at a time:
- Change retirement timing. A later date can add saving years, delay withdrawals, and potentially change benefit timing. Compare the tradeoff with a retirement number estimate.
- Adjust the spending plan. Separate essential costs from discretionary choices. Do not cut healthcare or other essential items simply to make a projection balance.
- Test savings contributions. Use a retirement savings projection to estimate how additional saving may change the starting balance. The how much to save each month guide can help translate a goal into a contribution.
- Review benefit timing. Compare personal Social Security estimates at different claim ages, including any household or survivor implications.
- Stress-test investments and withdrawals. A constant return smooths out market volatility. Test lower returns, lower withdrawal rates, and poor early-retirement performance. A retirement withdrawal strategy comparison can help you examine alternatives.
- Verify taxes and account rules. Taxable withdrawals may reduce spendable income, and account rules can affect access and required distributions.
Income planning may also include rental cash flow or dividends, but include net income after expenses rather than gross receipts. The purpose is to build a plan with assumptions you can explain and update—not to force every input to match a desired result.
Frequently Asked Questions
Quick answers to the questions people usually have after running the retirement calculator.
1Is 53% expense coverage enough to retire?
Not by itself; the 53% default result is the first-year after-tax income divided by first-year expenses, not a complete pass-or-fail retirement test. The projection also models later income, withdrawals, and the balance over time, and a shortfall may be covered from assets. Assess the full timeline and the consequences if assumptions are wrong.
2Why does the default projection show no Social Security at age 65?
Both default Social Security start ages are 67, so the benefits have not begun in the first projected year. The calculator starts each payment at its entered age; changing that age changes the income timing and potentially the monthly benefit you should enter.
3Does the 4% withdrawal rate mean the portfolio is safe?
No. The calculator uses 4% to set an annual withdrawal from the starting balance, but the rate is not a guarantee of sustainability. Investment sequence, fees, inflation, taxes, and retirement length can all change the outcome.
4Why does the model use 15% tax instead of calculating my taxes?
The input is a simplified flat-rate estimate, which makes the projection easier to compare but cannot reproduce progressive tax brackets or all sources’ tax treatment. Use a tax calculation for filing or withdrawal decisions, and treat this result as a rough after-tax planning view.
5Should I claim Social Security earlier or wait?
That is a tradeoff between receiving payments sooner and the monthly benefit available later, with health, cash-flow needs, work history, and survivor considerations affecting the decision. Compare estimates at different ages rather than choosing from this calculator’s income gap alone.
6Does the projection include inflation on every income source?
No. It applies the entered COLA to Social Security and pension income, general inflation to part-time, rental, and other income, general inflation to essential and discretionary expenses, and healthcare inflation to healthcare costs. These are model assumptions; adjust them to match the terms of each income source.
7Why can savings run out before life expectancy?
The modeled withdrawals and expenses can exceed the growth and remaining portfolio balance. In the default projection, savings last until age 88 while the model continues through 90. The result does not mean every income source ends at age 88; it means the modeled savings are exhausted by then.
8Should I include rental income before expenses?
Use net rental income if possible. Gross rent can overstate spendable cash because it omits repairs, vacancies, insurance, taxes, management, and other property costs. Model those costs in expenses if your rental estimate is gross.
9What does the lifetime income total include?
It sums the modeled income over all projected years, including applicable benefits, withdrawals, and other income. It is a nominal total across years, not its value in today’s dollars and not an amount available as a lump sum.
10Does this calculator determine my RMD?
No. It uses a withdrawal-rate assumption and does not calculate a required minimum distribution for each account. RMD ages and amounts depend on federal rules, account type, and beneficiary circumstances; check current IRS guidance.
11How should I handle a projected shortfall?
Identify when the gap occurs and which assumption drives it, then compare choices such as spending, work duration, retirement timing, benefit start age, and withdrawal rate. Do not assume investment returns will make up the difference.
12Can I rely on the investment-return assumption every year?
No. The calculator uses a smooth return for projection, while actual returns vary and may be negative. Test less favorable assumptions and consider how an early market decline could affect withdrawals.
Use the age-by-age results as a starting point, then verify benefit estimates, expenses, and taxes before turning the projection into a retirement decision.
