Personalized Insights
Actionable recommendations based on your numbers
Backdoor Roth is your path to Roth contributions
Your MAGI of $200,000 exceeds the single Roth IRA limit of $161,000. The backdoor strategy lets you contribute to a Roth IRA regardless of income — it's completely legal and IRS-approved.
Clean conversion — no pro-rata issue
With $0 in pre-tax Traditional IRA balances, your backdoor Roth conversion is tax-free. This is the ideal setup. Keep it clean by avoiding deductible Traditional IRA contributions.
$137,776 more by going Roth
Over 25 years, the backdoor Roth gives you $137,776 more after-tax money at retirement compared to investing the same amount in a taxable brokerage account. The longer the time horizon, the bigger the advantage.
$298,735 in tax-free growth (63% of total)
Your Roth IRA will grow from $175,000 in contributions to $473,735. That $298,735 in growth will never be taxed — not on dividends, capital gains, or withdrawals.
No Required Minimum Distributions
Unlike Traditional IRAs, Roth IRAs have no RMDs during your lifetime. Your money can continue growing tax-free as long as you want, and you can pass it on tax-free to heirs.
Consider the mega backdoor Roth for even more tax-free savings
If your employer's 401(k) allows after-tax contributions with in-service conversions, you could contribute up to $30,000-$46,500 more per year into a Roth account. Enable this in Advanced Settings to see the impact.
25 years of tax-free compounding
With 25 years until retirement, the power of tax-free compounding is enormous. Even $7,000/year grows to $473,735 — and every dollar is tax-free.
