Is this a guarantee?
No. Returns vary. This is a projection based on a constant annual return assumption.

How it works
The calculator projects growth using two components: your existing savings growing at compound interest, and your monthly contributions accumulating with compound growth (future value of an annuity). The formula compounds monthly for accuracy. Total = Current Savings × (1 + r)^n + Monthly × ((1 + r)^n − 1) / r, where r is the monthly rate and n is the total months. This is the same math financial advisors use for retirement projections.
Practical example
Starting with $50,000 in savings, contributing $500/month at 7% annual return for 25 years: your initial savings grow to about $271,372, and your contributions grow to about $405,168, for a total of roughly $676,540. You contributed $200,000 out of pocket — the rest is compound growth.
Frequently asked questions
Reusable FAQ content keeps each calculator page richer for users and search engines.
Does it include taxes?
No. The result is pre-tax. Your actual amount may differ after taxes.
What return rate should I use?
Historically, a diversified portfolio averages around 6-8% per year, but past performance does not guarantee future results.
How much do I need to retire?
A common rule of thumb is 25× your annual expenses (the "4% rule"). If you spend $40,000/year, aim for $1,000,000 in retirement savings.
Should I use a pre-tax or post-tax return rate?
If your retirement account is tax-deferred (401k, traditional IRA), use the pre-tax rate. For Roth accounts, the returns are already tax-free.
