5 Year CAGR Formula Excel

What this does

CAGR smooths a multi-year change into one annual rate — the constant rate that would carry the starting value to the ending value over the period. It strips out the noise of bumpy year-to-year swings so two investments over different horizons can be compared on equal footing. Because it is a geometric mean of growth, it is the honest way to summarise compounding, where a simple average would overstate the return. Most people learn this as a sequence of clicks and forget it by next week; learning it as a pattern instead is what lets you apply it to the next, slightly different version of the problem without starting from scratch. That is the difference this page is trying to make. Treat “5 year cagr formula excel” as a small repeatable workflow rather than a one-off click you hope to remember next time. Use a small test block before the live file, so any surprise in the affected formula shows up while it is still harmless. When a formula is involved, keep the inputs labelled beside it, reference cells instead of typing values, and apply number formatting only after the result checks out. That turns a calculation you can defend to a CFO or an auditor into a method you can reuse, explain, and defend when the workbook leaves your screen.

A worked example

Say a fund grew from €10,000 to €19,672 over 10 years. Enter =(19672/10000)^(1/10)-1 and format as a percentage: the result is 7.0%. That single figure means the fund effectively earned 7% every year, compounded — even though the real path was lumpier. Change the ending value to €25,000 and the rate jumps to 9.6%, which is exactly what the live chart above redraws as you type. Reach for CAGR whenever you need to compare growth over different time spans or report a single, defensible annual figure to a board or client. It is the standard language of investment and revenue reporting precisely because it is comparable and hard to game. One habit worth forming early: name the cells that hold your inputs, so the formula reads in plain language instead of a string of cell addresses. A reviewer — or you in three months — can then follow the logic without decoding what B7 and D2 were supposed to mean, which is most of what makes a sheet maintainable.

In Google Sheets

If you are in Google Sheets rather than Excel, the good news is that the formula shown here is identical and the workflow barely changes — menus sit across the top instead of in a ribbon, and a few function names differ slightly, but anything you build here moves across with little or no rework. The aim was to get you unstuck fast and leave you a little more capable than a copy-paste would. The answer is at the top, the tool proves it, and the detail above shows why it holds — so the next time a colleague asks, you can answer without reaching for search. The short version of “5 year cagr formula excel”: the answer is at the top of this page, the tool proves it on your own numbers, and the sections above explain why it holds so the next variation does not stump you. Excel rewards people who reference cells instead of typing values and who keep inputs separate from formulas, because that is what makes a result you can audit months later. Build it once, deliberately, with the live tool as a check, and you convert a one-off lookup into a reusable skill — which is the whole point of learning the why and not just the what.

Common mistakes

• Using a simple average of yearly returns — it overstates compounded growth; CAGR is the geometric rate.
• Counting the wrong number of years (use elapsed years, not the count of data points).
• Feeding a zero or negative starting value, which makes the ratio meaningless.
• Leaving the cell as a raw decimal (0.07) instead of formatting it as 7%.
