Roth IRA Calculator
A Roth IRA Calculator helps estimate how your retirement savings grow over time in a Roth IRA, where contributions are made with after-tax income and qualified withdrawals are tax-free in retirement.
What is a Roth IRA?
A Roth IRA (Individual Retirement Account) is a retirement savings account where you pay taxes upfront, but your money grows tax-free and can be withdrawn tax-free in retirement if conditions are met.
- Funded with after-tax income
- Tax-free growth over time
- Tax-free withdrawals in retirement (if qualified)
- No Required Minimum Distributions (RMDs)

How Roth IRA Growth is Calculated
Roth IRA growth is based on compound interest, contributions, and investment returns over time.
Future Value Formula
FV = P (1 + r)^t + Regular Contributions Growth
- P = initial investment
- r = annual return rate
- t = time in years
Example Roth IRA Growth
If you invest $6,000 per year for 30 years with a 7% average return:
Estimated Value ≈ $500,000 – $650,000 (tax-free in retirement if qualified)
