Understanding your result
The outputs describe the mathematical scenario you entered. Assumed rates, timing and included costs determine the result; an estimate is not an offer or eligibility decision.
Common mistakes
- Mixing annual and monthly periods, or leaving out a cost that the model does not include.
Check your calculation
- Compare a simple one-period or zero-change case with hand arithmetic before applying a longer scenario.
Calculation checks, sources and review limits
What percentage have I added to my cost to set the selling price?
Compare the selling price with cost to see the markup percentage. The denominator is cost, so markup differs from profit margin.
Common uses
- Check a product’s cost-based markup.
- Compare markup percentages across selling prices.
How it works
Markup divides profit by cost. Margin instead divides profit by the selling price. Cost must be positive. A price below cost produces a negative markup. Use matching tax bases and include the costs relevant to your comparison.
Worked example
Cost 60 and price 100 produce profit 40 and markup of 40 ÷ 60 × 100 ≈ 66.6667%. The profit margin is 40%.
