Roth IRA Max-Out Growth Calculator 2025
Two questions decide your retirement number: how much you put in and how long it compounds. Most calculators do one or the other. This one does both — it caps each year’s contribution at the real 2025 IRS limit for a Roth IRA and then compounds it to your retirement age.
For 2025 the Roth IRA limit is $7,000 (+$1,000 catch-up at age 50+). The age-50 catch-up and are applied automatically in the years you qualify — the tool raises and lowers your cap as you cross each age band, so a multi-decade projection stays accurate. Roth contributions are after-tax, so qualified growth and withdrawals are tax-free — this projection shows the full tax-free balance.
Enter your current age, target retirement age, starting balance and expected annual return. Tick “contribute the IRS maximum every year” to see the ceiling, or untick it to model your own amount (it is still clamped to the legal limit). Everything runs in your browser — no figures are transmitted.
