Formula
Compound interest grows by applying interest to the principal and to interest already earned. The calculator also estimates the future value of recurring deposits when you save or invest on a schedule.
Planning note
The result depends on the rate, compounding frequency, contribution timing, taxes, fees, and inflation assumptions you enter. Actual savings, investment, or loan outcomes can be different.
Use cases
Use it to estimate savings growth, investment compounding, recurring deposits, interest earned, and long-term goal planning.
Use the result as a planning estimate, then verify important savings, investment, tax, or borrowing decisions with a qualified professional.

Questions
It estimates future value, compound interest earned, total deposits, effective annual rate, inflation-adjusted value, after-tax balance, goal contribution needs, and compounding-frequency comparisons based on the values you enter.
Compound interest is interest calculated on both the original principal and previously earned interest. Over time, this can make balances grow faster than simple interest.
More frequent compounding can increase the final balance, but the difference is usually modest unless the rate, timeline, or balance is large. The comparison tab helps you see the difference.
No. It is for educational planning only. Actual returns, savings rates, fees, taxes, inflation, account rules, and investment performance can vary. Review important decisions with a qualified professional.
