Examples
- $200/mo, APR 5%, 36 months ⇒ $7,549.94 accumulated
- $350/mo, APR 7%, 120 months ⇒ $50,721.90 accumulated
- $500/mo, APR 0%, 24 months ⇒ $12,000 accumulated
FAQ
What if my contributions happen at the beginning of the month?
That scenario is an annuity due. Multiply the result by (1 + periodic rate) to adjust for beginning-of-period deposits.
Can I change the compounding frequency?
This calculator compounds monthly. To use quarterly or annual compounding, adjust the formula to match the desired frequency.
How do I enter an APR below 1%?
Use decimals such as 0.75 for 0.75% APR. The tool accepts fractional rates for more accuracy.
Is inflation considered?
No. The calculation provides nominal dollars. To account for inflation, discount the result by your expected inflation rate.
Additional Information
- This formula assumes payments occur at the end of each period, also called an ordinary annuity.
- Monthly compounding uses the periodic rate APR ÷ 12. Adjust the months and payment to match your saving plan.
- If the APR is zero, the future value equals the total contributions because no interest accrues.
- Use the result to set savings goals for retirement, tuition funds, or sinking funds.
