If you are asking, “how do I calculate return on investment in Excel?”, the good news is that it is simple once you know the formula and where to put it. ROI is one of the fastest ways to compare investments, business projects, or even marketing campaigns.

What is ROI?

ROI (Return on Investment) tells you how much profit you earned compared with how much you invested. It is usually shown as a percentage.

ROI = (Net Profit / Total Investment) * 100

Where:

Net Profit = Ending Value - Total Investment
Total Investment = Initial Investment + Additional Costs

How to calculate ROI in Excel (step by step)

1) Set up your worksheet columns

Create these headers in row 1:

A1: Initial Investment
B1: Additional Costs
C1: Ending Value
D1: Net Profit
E1: ROI %

2) Enter your numbers

Example row in row 2:

A2 = 10000
B2 = 500
C2 = 13000

3) Add formulas

Use these formulas exactly:

D2: =C2-(A2+B2)
E2: =D2/(A2+B2)

Then format E2 as a percentage (Home → Number → %).

In one line, you can also write ROI directly as:
=(C2-(A2+B2))/(A2+B2)

How to calculate annualized ROI in Excel (CAGR)

Simple ROI is useful, but it does not account for time. If one investment took 1 year and another took 5 years, annualized return is better.

Use this Excel formula if years are in F2:

=((C2/(A2+B2))^(1/F2))-1

Format the result as a percentage. This gives annualized ROI (CAGR).

Common mistakes to avoid

Ignoring fees: transaction fees, taxes, commissions, and maintenance costs should be included.
Dividing by the wrong number: divide by total investment, not ending value.
Mixing time periods: compare annualized returns when investment durations differ.
Using ROI for uneven cash flows: if money is added/removed over time, IRR or XIRR may be better.

When to use ROI vs IRR/XIRR in Excel

Use ROI when there is one clear start amount and one clear ending amount. Use IRR or XIRR when cash flows happen at multiple points in time.

ROI: quick, easy comparison metric
IRR: periodic cash flows
XIRR: irregular dates and real-world cash flow timing

Quick Excel ROI template formulas

Net Profit:
=C2-(A2+B2)

ROI:
=(C2-(A2+B2))/(A2+B2)

Annualized ROI (Years in F2):
=((C2/(A2+B2))^(1/F2))-1

Final thoughts

To calculate return on investment in Excel, remember this structure: profit over cost. Keep your inputs consistent, include all costs, and use annualized ROI when time matters.
