Frequently asked questions

What is Project ROI calculator?

Compute profit and return on investment from cost and revenue.

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.

How is Project ROI calculator different from ROI calculator (return on investment)?

They sit next to each other but answer different questions. ROI calculator (return on investment): work out your return on investment as a percentage from the amount invested and the amount returned. Pick whichever matches what you're starting from — both are free.

Is there a tool for the next step?

Side hustle ROI calculator is the closest one after this: Is your side hustle actually worth it? From revenue, running costs, hours and any start-up spend, it works out profit, the return on investment, and your real hourly rate — then compares that against your day-job wage so you can see if the time pays off.

Where do the figures come from?

The arithmetic is exact for what you enter. Invoice content, VAT treatment and mandatory mentions are set by national rules — an invoice that computes correctly can still be non-compliant.

The value is avoided cost plus recovered time — and on a $130,000 migration, 60.5 % of the recovered hours have to be genuinely redeployed before the five-year net present value even reaches zero.ExplainerFifty-Five Days to Get Paid on Thirty-Day Terms180,000 outstanding against 1,200,000 of annual sales is 54.75 days of collection and 6.67 turns a year. On thirty-day terms, that gap is a quarter of a million financed for free.ExplainerFifty Thousand of Working Capital, and None of It SpendableCurrent assets of 150,000 less current liabilities of 100,000 gives working capital of 50,000 and a ratio of 1.5. Whether that is comfortable depends on what the 150,000 is made of.How-toWhat Is ROI and How Do You Calculate It?ROI measures your gain relative to what you invested, as a percentage. Here's the formula, a worked example, and what ROI leaves out.ExplainerDepreciation Is the Only Expense That Never Leaves the BankA $24,000 van with a $4,000 residual over five years is $4,000 a year of expense and not one dollar of payment.

Against a cost of capital of 8 % that is a spread of 17 points; at 6 % it would be a spread of −2, and every extra euro invested would destroy value.
