Business calculators

Choose the right calculator

A selling price, a sales target and a return percentage answer different business questions. Use these five tools to connect costs with revenue, check pricing and compare performance without a spreadsheet.

• Profit Margin Calculator — Measure profit as a share of revenue when reviewing how much of each sale remains after the costs you enter.

• Markup Calculator — Measure the amount added to cost. Margin and markup use different denominators, so the same percentage does not mean the same selling price.

• Break-Even Calculator — Find the sales volume that covers fixed and variable costs at a chosen unit price.

• ROI Calculator — Compare net gain with the original investment cost. This is a total return, without an adjustment for time.

• Revenue Growth Calculator — Compare revenue across two periods of the same length to measure an increase or decrease.

Before you calculate

Use the same currency and accounting period for comparable inputs. Decide which costs belong in your calculation: gross margin does not automatically include overhead, taxes or every operating expense. Break-even assumes a constant unit price and variable cost.

A practical example

If a product costs $60 and sells for $100, its gross profit is $40. The margin is 40% of revenue, while markup is about 66.67% of cost. Check margin and markup together before applying a percentage to a price.
