Reverse CAGR formulas

Future Value = Starting Value × (1 + CAGR)Years

Starting Value = Future Value ÷ (1 + CAGR)Years

Years = ln(Future Value ÷ Starting Value) ÷ ln(1 + CAGR)

When to use this calculator

Reverse CAGR is useful when the annual compound rate is already known and you need to project a value, recover the implied beginning value, or estimate the time required to reach a target.

For calculations with deposits or withdrawals on different dates, CAGR may not represent the investor's actual return. A cash-flow-aware measure such as IRR or XIRR can be more appropriate.
