About Compound Growth / CAGR / Investment Return Calculator
Compound Growth / CAGR / Investment Return Calculator separates CAGR, total growth and future-value projection so each metric has a clear definition.
CAGR annualizes two endpoint values over a stated duration. Compound projection applies a stated annual rate and compounding frequency, with optional periodic contributions. Results are mathematical scenarios, not investment forecasts. Compounding is exponential: money grows slowly, then suddenly. The calculator shows year-by-year growth so you can see the inflection point where returns start dwarfing contributions — the visual that convinces people to start early. Calculator results depend on the inputs, units, assumptions, formulas and reference date or rate where applicable. Confirm units and assumptions, compare the result with a known example when possible, and verify current external rates or rules.
Primary objective: Calculate investment growth over time with initial principal, regular monthly deposits, interest rate, and compounding frequency.
Privacy assurance: The calculation is performed locally in the browser from the values you enter.

Frequently Asked Questions
What is CAGR?
CAGR is the constant annualized rate that mathematically connects a starting value and ending value over a defined number of years.
Is CAGR the actual return every year?
No. It is an annualized endpoint measure and does not describe the path or volatility between the endpoints.
Are future-value results guaranteed?
No. They apply the rate and timing assumptions entered by the user and do not predict actual investment performance.
What is the difference between APR and APY?
APR is the nominal rate; APY includes compounding frequency. Monthly compounding at 6% APR is ~6.17% APY. Always compare APYs, not APRs.
How often should interest compound?
More frequent compounding helps slightly, but the rate and time dominate. Daily vs monthly compounding on the same APR differs by fractions of a percent.
What is the Rule of 72?
Divide 72 by your interest rate to estimate doubling time: 72/6 ≈ 12 years. A handy sanity check on calculator results.
