How is the value of a Roth IRA calculated?
Each year the balance grows by the expected return, then the annual contribution is added; total growth is the final balance minus everything you contributed. Because Roth contributions are made with after-tax money, qualified withdrawals — including all the growth — are tax-free. Contributing 7,000 a year from age 30 to 65 at 7% grows into a substantial tax-free balance.
Understanding your result
Roth contributions are made with after-tax money, so qualified withdrawals in retirement — including all the growth — are tax-free. That makes long-term compounding especially valuable.
Formula and method
Each year the balance grows by the expected return, then the annual contribution is added. Total growth is the final balance minus everything you contributed.
Assumptions and limitations
A simplified annual model that excludes fees, inflation and changing contribution limits. Contribution limits and eligibility depend on your income and the tax year.
Worked example
Contributing 7,000 a year from age 30 to 65 at a 7% return grows into a substantial tax-free balance, most of which is investment growth rather than contributions.

Frequently asked questions
Why is a Roth IRA “tax-free”?
You contribute after-tax money, so qualified withdrawals in retirement — including investment growth — are not taxed again.
What is the contribution limit?
For 2025 it is 7,000 per year, or 8,000 if you are age 50 or older, subject to income limits.
Why does starting earlier make such a difference?
Because the balance compounds each year, contributions made earlier have more years to grow, and in a Roth that entire growth can be withdrawn tax-free when qualified. Over a long horizon the accumulated growth often exceeds the total you contributed, which is why time in the market matters so much.
