Compound Interest Growth Calculator

Model principal growth with recurring deposits and selectable compounding schedules for savings-style estimates.

What does compounding frequency change?

More frequent compounding applies interest more often within the year, which slightly increases effective yield for the same nominal annual rate.

Does this include taxes or fees?

No. Real accounts may withhold tax or charge fees. Treat outputs as pre-fee mathematical projections.

Is past market performance assumed?

You supply the rate. The calculator does not forecast markets; it compounds the rate you enter.
