DuPont Analysis Calculator
Enter net income, net sales and beginning and ending total assets and total equity using one reporting period, currency and scale. Review average balances, three factors and a direct ROE cross-check.
A QUICK WALKTHROUGH
How to use this tool
- Enter all six same-period amounts with matching currency and scale.
- Calculate mean assets and equity, profit margin, asset turnover and the equity multiplier.
- Compare three-factor ROE with net income divided by average equity.
Three-factor identity
(NI / sales) × (sales / average assets) × (average assets / average equity) = NI / average equity. Average balances are the arithmetic mean of beginning and ending values. Understanding Accounting: https://understandingaccounting.org/concepts/dupont-analysis/.
Limits and reconciliation
Sales, average total assets and average total equity must be nonzero. Signed inputs are retained. Finite results are required; floating-point arithmetic may leave a small difference. Arithmetic agreement establishes neither causality nor business quality, forecasts or investment advice.
GOOD TO KNOW
Common questions
Which period and units should I use?
Use the same reporting period, currency and scale for all inputs. Asset and equity balances must be the beginning and end of that period. No annualization is applied.
What happens with zero denominators?
The tool rejects zero net sales, zero average assets or zero average equity because the three-factor identity is then undefined.
Are my financial values uploaded?
No. You enter the values manually and the browser calculates locally without fetching statements or storing inputs.
