How to use this roi calculator
Measure return on investment from gain and investment cost. Enter realistic figures from your own business and test different scenarios before making a pricing or planning decision.
Why this matters
Small changes to price, cost, volume or percentage assumptions can have a large effect on profitability. A simple model makes those trade-offs visible before you commit.
Good practice
- Use current, realistic inputs rather than best-case estimates.
- Keep gross profit separate from net profit and cash flow.
- Re-run the calculation when your costs or commercial terms materially change.
