What this future value calculator does

Future value estimates what a savings or investment plan will be worth after a number of periods. This calculator combines a starting amount, a regular deposit, a fixed interest rate, and the timing of each deposit.

It is useful for setting savings targets, comparing deposit amounts, and seeing how much of the ending balance comes from contributions versus interest.

How to use this calculator

Enter the number of periods.
Enter the starting amount.
Enter the interest rate per period.
Enter the amount deposited each period.
Choose whether deposits are made at the beginning or end of each period.
Click Calculate.

The default example starts with $1,000, deposits $100 at the end of each period for 10 periods, and earns 6% per period. The future value is $3,108.93.

Future value formula

For end-of-period deposits:

FV = PV × (1 + r)^n + PMT × ((1 + r)^n − 1) / r

PV is the starting amount, PMT is the periodic deposit, r is the interest rate per period, and n is the number of periods. If deposits are made at the beginning of each period, the deposit term is multiplied by (1 + r).

The present value shown in the results is the amount that would need to be invested today at the same rate to produce the same future value.

What the results include

Future value: the projected ending balance.
Present value: the value today of the projected balance.
Starting amount: the initial balance.
Total deposits: the sum of the periodic deposits, excluding the starting amount.
Total interest: the future value minus the starting amount and total deposits.
Accumulation schedule: yearly deposits, interest, and ending balance.
Growth chart: balance, cumulative deposits, and cumulative interest.

Assumptions and limitations

The calculator assumes a constant interest rate and equal deposits. Each period is treated as one year in this version, and the plan supports up to 50 periods. Taxes, inflation, fees, and variable returns are not included. Deposits are assumed to be made on time at the selected point in each period.

Frequently asked questions

Does future value include inflation?

No. The result is a nominal future balance. Inflation would reduce its purchasing power.

What happens if deposits are made at the beginning of the period?

Each deposit has one extra period to earn interest, so the future value is slightly higher than with end-of-period deposits.

Why is the present value lower than the future value?

The present value is discounted back to today. With a positive interest rate, a dollar today grows into more than a dollar in the future.

Can I use this for a retirement account?

Yes, as a simple projection. It does not model contribution limits, employer matches, taxes, or investment fees.
