Reverse CAGR Calculator
Flip the CAGR question around: pick a starting value and a growth rate, and see what it becomes.
How the Reverse CAGR Calculator Works
Reverse CAGR answers the opposite question from a normal CAGR calculator: instead of finding the rate from two values, it finds the future value from a rate. The formula is: Future Value = Start Value × (1 + Rate)^Years.
Example: $10,000 compounding at 10% a year for 20 years becomes $10,000 × 1.10^20 = about $67,275. The gain is $57,275 — more than five times the starting amount — which shows why starting early matters so much.
This assumes one lump sum with no deposits or withdrawals, and a constant rate every year. Real investments vary year to year, so treat the result as a projection, not a prediction.
