Growth Rate Needed
Divide the target by the start to see the multiple needed, then take the year-th root. Tripling in five years needs 24.6% a year — not the 40% you get by dividing 200% growth by five.

Formula
Growth needed = ((Ending value ÷ Starting value) ^ (1 ÷ Years) − 1) × 100
Because it compounds, the absolute gains arrive late. Falling behind the line in the early years is expected.
What to enter
| Input | Default | Accepted range |
|---|---|---|
| Starting valueWhere the growth starts from. | 100,000,000 | 1 and up |
| Ending valueWhere you want to be when the period ends. | 300,000,000 | 1 and up |
| Years (yr)How many years the money stays put; compounding bites harder as this grows. | 5 | 1 ~ 60 |

Frequently asked questions
QHow is Growth Rate Needed calculated?
Growth needed = ((Ending value ÷ Starting value) ^ (1 ÷ Years) − 1) × 100 — Divide the target by the start to see the multiple needed, then take the year-th root. Tripling in five years needs 24.6% a year — not the 40% you get by dividing 200% growth by five.
QCan you walk through an example?
With Starting value 100,000,000, Ending value 300,000,000, Years 5yr, the answer is Growth needed 24.57%.
QWhat do I need to enter?
Enter Starting value, Ending value, Years. The result recalculates as you type, and an empty box counts as zero.
QHow much does the answer move if I change a number?
Changing only Starting value moves the answer to Starting value 50,000,000 → Growth needed (%) 43.1 and Starting value 200,000,000 → Growth needed (%) 8.45. The table below lays out five steps.
QHow are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
QAnything to watch out for?
Because it compounds, the absolute gains arrive late. Falling behind the line in the early years is expected.
