Daily Compound Interest Calculator
See how money can grow when interest is compounded daily. Enter the starting amount, rate, time, and other inputs to explore the result. It can make a financial figure easier to understand before you compare options or enter the numbers into a larger budget.
How to use this calculator
Enter the starting amount and the rate or time values requested. Check whether the rate is annual and whether compounding or contributions are included before comparing the result with another estimate.
Formula
For periodic compounding, A = P(1 + r/n)^(nt); daily compounding uses n = 365 (or the convention selected by the tool).
A useful way to check it
Use the calculator as a quick verification tool as well as a way to get the final number. Understanding what the result represents is just as important as the number itself. Financial results can change with rates, fees, taxes, dates, and the assumptions entered. Treat the figure as an estimate and verify important numbers against the terms that actually apply.
