Compound Interest Calculator vs CAGR Calculator
Two calculators for the same neighbourhood of questions. Here is what each measures, what you feed in, and where you'd reach for one over the other.
Compound Interest Calculator
Project the future value of an investment given a lump-sum principal, recurring monthly contributions, an annual rate, and a compounding frequency. Use it for long-horizon planning — retirement, college funds, or any goal where reinvested earnings drive the bulk of growth.
- Answers
- Future Value ($)
- Inputs
- Initial Investment, Monthly Contribution, Annual Interest Rate, Time Period, Compounding Frequency
CAGR Calculator
Calculate the compound annual growth rate (CAGR) — the constant per-year rate that turns an investment's starting value into its ending value. Use it to compare funds, portfolios, or business metrics that grew at uneven annual rates on a level playing field.
- Answers
- CAGR (%)
- Inputs
- Initial Investment Value, Final Investment Value, Number of Years
