REDUX is a military retirement option associated with the Career Status Bonus (CSB) and a reduced retired-pay multiplier. This calculator compares a modeled Redux benefit with a High-3 benefit, projects the bonus’s future value, and estimates the difference in discounted lifetime pension values.
Under the default assumptions, the calculator estimates $2,600 monthly Redux pay, compared with $3,250 under High-3. It projects a $42,077 future value for the $30,000 bonus and a −$304,988 NPV difference for Redux relative to High-3. The comparison depends heavily on service, lifespan, COLA, investment return, and discount rate.
Enter Service, Pay, and Assumptions
Enter base pay at retirement, years of service, current age, life expectancy, investment return on the bonus, inflation, discount rate, and COLA. In this calculator, current age is also treated as retirement age for the benefit projection. That matters: the default current age of 40 creates a 42-year projection through age 81.
The defaults use $6,500 monthly base pay and 20 years of service. The calculator applies a 2.0% Redux multiplier and a 2.5% High-3 multiplier per service year. It assumes the $30,000 bonus grows for five years, from year 15 to year 20, at 7%.
The CSB/Redux election is a historical arrangement for eligible members under applicable rules; it is not a standard choice available to every service member today. Check official eligibility and election details with DFAS and current service guidance. For general pay estimates, compare the Military Retirement Calculator and Military High-3 Calculator.
How the Default Comparison Works
For 20 years of service, the Redux multiplier is 20 × 2.0% = 40%, while the High-3 multiplier is 20 × 2.5% = 50%. Annual base pay is $6,500 × 12 = $78,000. Redux annual pay is $78,000 × 40% = $31,200, or $2,600 monthly. High-3 annual pay is $78,000 × 50% = $39,000, or $3,250 monthly.
That creates a starting difference of $3,250 − $2,600 = $650 per month in favor of High-3. The calculator estimates the bonus future value as $30,000 × 1.07^5 = $42,077. It adds this modeled bonus value to the Redux cumulative comparison; it does not treat the bonus as monthly pension income.
| Years of service | Redux multiplier | Redux monthly pension | High-3 multiplier | High-3 monthly pension |
|---|---|---|---|---|
| 20 | 40% | $2,600 | 50% | $3,250 |
| 24 | 48% | $3,120 | 60% | $3,900 |
| 30 | 60% | $3,900 | 75% | $4,875 |
The table holds monthly base pay at $6,500 and varies service years. It does not add COLAs, bonus investment growth, or present-value effects. At the 30-year row, the High-3 multiplier reaches the calculator’s 75% cap.
COLA Rules and the Break-Even Estimate
The calculator models Redux COLA as one percentage point below the entered full COLA rate, with a minimum of zero. At the default 3% COLA, that produces a 2% Redux adjustment and 3% High-3 adjustment in the projection. The model includes a catch-up convention at age 62 for people retiring before 62. Specific historical Redux rules and an individual member’s benefit should be confirmed with official guidance rather than inferred from this simplified model.
The default projection reports a break-even age of 44, where cumulative High-3 payments first exceed the modeled Redux cumulative total after the bonus value is included. This is an output of the calculator’s assumptions, not a guarantee that a member will be financially better off by that age. A different lifespan, bonus return, inflation rate, or discount rate can change the comparison.
The calculator estimates Redux lifetime income of $2,346,364 and High-3 lifetime income of $3,198,904, a difference of −$852,540 for Redux. Discounted at 5%, it estimates Redux NPV of $829,583 and High-3 NPV of $1,134,571, creating the displayed −$304,988 NPV difference. These lifetime totals include projected pension income; they should not be mistaken for a current cash value or guaranteed outcome.

Formula and Default Arithmetic
The calculator compares two service multipliers, grows the modeled bonus, and sums future payments under separate COLA and discount assumptions.
High-3 multiplier = lesser of (years of service × 2.5%) or 75%
Redux multiplier = lesser of (years of service × 2.0%) or 75%
Monthly pension = (monthly base pay × 12 × multiplier) ÷ 12
Bonus future value = $30,000 × (1 + bonus investment return)^(years of service − 15)
NPV difference = discounted Redux pension value − discounted High-3 pension value
With 20 years of service, the High-3 multiplier is 20 × 2.5% = 50%; $6,500 × 50% = $3,250 monthly. Redux is 20 × 2.0% = 40%; $6,500 × 40% = $2,600 monthly. The bonus grows for 20 − 15 = 5 years: $30,000 × 1.07^5 = $42,077. The calculator’s discounted values are $829,583 and $1,134,571, so $829,583 − $1,134,571 = −$304,988.
Redux and High-3 Questions
Is the $30,000 CSB available to every service member?
No. Redux and the CSB were tied to specific eligibility and election rules. This calculator assumes a $30,000 bonus for comparison; it does not establish eligibility or show whether an election is currently available to a particular member.
Does a 2% Redux multiplier mean 2% of base pay total?
No. It is 2% per year of service in this model. At 20 years, 2.0% × 20 = 40% of the applicable pay base.
Why can Redux have a larger cumulative total early in the projection?
The model includes the CSB’s assumed future value at the start of its cumulative comparison. That can make early cumulative Redux totals larger even when its monthly pension is lower. The later pension stream may change the comparison over time.
Should I compare the bonus’s future value with a pension’s NPV?
Only if the assumptions are comparable. Bonus investment return, taxes, timing, investment risk, COLA, lifespan, and discount rate all affect the result. A projected investment return is not guaranteed.
What does the age-62 COLA catch-up represent?
The calculator models a catch-up feature for certain pre-62 retirement projections. It is a simplified benefit convention; confirm the governing rules for the member’s specific election and service history.
Should I choose a higher bonus return or a lower pension discount rate?
A higher bonus return increases the modeled bonus value. A lower discount rate raises the present value of future pension payments. Both assumptions can shift the comparison, so test a range instead of relying on one favorable scenario.
Does the calculator include taxes or survivor benefits?
No. It does not calculate tax withholding, SBP cost, or survivor benefits. Review the Military SBP Calculator and tax treatment separately.
Next Steps Before Comparing Options
First verify which retirement system and election rules apply to the member. Then test the assumptions that drive the result: years of service, age, lifespan, COLA, discount rate, and expected return on the bonus. Compare the outputs with the Military Retirement Calculator and Military Pension Calculator.
