How to Calculate Rate of Return in Excel

Calculating the Rate of Return (RoR) is a fundamental skill for financial modeling. In Excel, you can calculate this using basic arithmetic or built-in financial functions depending on whether you need a simple return or an annualized figure.

1. The Simple Rate of Return Formula

This calculates the total growth of an investment from start to finish. In Excel, if your Initial Investment is in cell A2 and your Final Value is in cell B2, the formula is:

=(B2 – A2) / A2

Pro Tip: Format the result cell as a "Percentage" to see it correctly.

2. The Annualized Return (RRI Function)

To find the Compound Annual Growth Rate (CAGR) when you know the number of periods, Excel provides the RRI function. If A2 is the number of years, B2 is the initial value, and C2 is the final value:

=RRI(A2, B2, C2)

3. Handling Cash Flows (IRR Function)

If you have multiple investments and withdrawals over time, use the IRR (Internal Rate of Return) function. List your cash flows in a column (initial investment as a negative number) and use:

=IRR(A2:A10)

Practical Example

Scenario	Initial	Final	Years	Excel Result
Stock Growth	$5,000	$7,500	3	14.47% (Annual)
Real Estate	$200,000	$350,000	10	5.76% (Annual)

FAQ: Why is my Excel RoR different from a simple average?

Simple averages don't account for compounding. If a portfolio drops 50% and then gains 50%, your average return is 0%, but your actual RoR is -25%. Always use geometric calculations (like CAGR or RRI) to measure true investment performance over time.
