What this savings calculator does

This calculator estimates the ending balance and interest earned on a savings plan. It supports an initial deposit, annual contributions, monthly contributions, and an annual percentage increase in those contributions.

Contributions are applied at the end of each period in this version. Taxes, inflation, and account fees are not included.

How to use this calculator

Enter the initial deposit.
Enter any annual or monthly contribution.
Enter the yearly increase in each contribution, if any.
Enter the interest rate, savings term, and compounding frequency.
Click Calculate to see the ending balance and yearly growth schedule.

Savings growth formula

For a lump sum, the compound interest formula is:

A = P × (1 + r / n)^(n × t)

Contributions are added each period. An annual contribution increase is applied once per year, so the next year's contribution is:

new contribution = current contribution × (1 + increase rate)

What the results include

Final balance: the estimated savings balance at the end of the term.
Total contributions: the initial deposit plus all contributions.
Total interest: the final balance minus total contributions.
Annual growth schedule: yearly contributions, interest, and ending balance.
Growth chart: balance, cumulative contributions, and cumulative interest.

Frequently asked questions

Does this calculator include taxes on interest?

No. Tax rates and tax-advantaged accounts are not modeled in this version.

Does it adjust for inflation?

No. The result is a nominal balance. Inflation-adjusted value is not included.

Are contributions made at the beginning or end of the year?

This version assumes end-of-period contributions. If you make deposits at the beginning of each period, the actual balance can be slightly higher.
