Add operating profit (EBIT) and it also returns the ROCE.Debt service coverage ratio (DSCR) calculatorThe DSCR — net operating income ÷ total debt service — tells lenders whether a property or business earns enough to cover its loan payments. A DSCR of 1.25 means income is 25% above the debt due, the level most commercial lenders require. Below 1.0 the cash flow cannot cover the debt.Debt-to-asset ratio calculatorThe debt-to-asset ratio — total liabilities ÷ total assets, expressed as a percentage — shows what share of a company's assets is financed by debt. A ratio of 40% means creditors fund 40% of the assets and owners the rest. It is a core solvency gauge; this is distinct from the debt-to-income ratio used for personal loans.EBIT calculatorCompute EBIT — earnings before interest and taxes — from operating revenue, operating expenses and any non-operating income.

Frequently asked questions

What does the Return on net assets calculator actually compute?

It takes Net income, Fixed assets, Working capital and Revenue (optional) and derives RONA, Net assets, Net margin and Net asset turnover (×) from them. The calculation is live as you type, so the result updates on every change.

What information do I need to provide?

4 values: Net income ($), Fixed assets ($), Working capital ($) and Revenue (optional) ($). Nothing else is required — no account, no file upload.

Can you show a worked example?

With Net income = $500,000.00, Fixed assets = $2,000,000.00, Working capital = $500,000.00 and Revenue (optional) = $3,000,000.00, the calculator returns RONA = 20%, Net assets = $2,500,000.00 and Net margin = 16.67%. Those figures come from running this exact tool, so you can reproduce them by entering the same values.

What happens if I enter larger values?

It moves a lot. Using Net income = $1,000,000.00, Fixed assets = $4,000,000.00, Working capital = $1,000,000.00 and Revenue (optional) = $6,000,000.00 instead, Net assets goes from $2,500,000.00 to $5,000,000.00 — which is why it is worth testing a few scenarios rather than trusting a single figure.

What does it give for smaller values?

Scaled down to Net income = $250,000.00, Fixed assets = $1,000,000.00, Working capital = $250,000.00 and Revenue (optional) = $1,500,000.00, Net assets comes out at $1,250,000.00. The relationship is worth checking at both ends before you rely on a single result.

When would I actually use this?

Running the week: issuing an invoice or a quote, knowing what is in stock and what to reorder, and seeing whether cash covers what is due.

What is the most common mistake?

Reading profit as cash. A profitable month with sixty-day payment terms can still leave the account empty — the two numbers answer different questions.

What is the difference between the Return on net assets calculator and the Return on assets (ROA) calculator?

This one returns RONA and Net assets; the Return on assets (ROA) calculator returns Return on assets. That is the whole difference — open the one whose figure you need.

Is there a tool for the next step?

Return on equity (ROE) calculator is the closest one after this: Compute return on equity from net income and shareholder equity.

What else is worth having open alongside it?

ROI calculator (return on investment) and Net profit margin calculator — they come up in the same task often enough to be worth a second tab.
