How It Works
How to Calculate Return on Assets
Formula
ROA = (Net Income / Average Total Assets) x 100
ROA tells you how many cents of profit each dollar of assets generates. It combines profitability and asset efficiency into a single metric. Companies with high ROA are squeezing strong profit from a lean asset base, which is a hallmark of well-managed businesses.
Worked Example
A company earned $150,000 in net income. Total assets were $900,000 at the start and $1,100,000 at the end.
net_income = 150000total_assets_start = 900000total_assets_end = 1100000
- 01Average Total Assets = ($900,000 + $1,100,000) / 2 = $1,000,000
- 02ROA = ($150,000 / $1,000,000) x 100 = 15%
- 03Each dollar of assets produced 15 cents of net income.
