| Period | Value |
|---|---|
| Start | $10,000 |
| 1 years | $11,246.83 |
| 2 years | $12,649.12 |
| 3 years | $14,226.25 |
| 4 years | $16,000.02 |
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.
