18.00% is the example result. Operating profit separates the operating result from financing and other non-operating items. Keep the classification consistent between periods.

Result = (([Operating profit]) ÷ ([Revenue])) × 100
Purpose

Compare operating profit with revenue to assess the return from normal operations. Keep finance and tax items consistent with the operating profit figure in your accounts.

Assess operating performance

This percentage uses the supplied operating profit. It does not convert gross profit to operating profit or classify expenses for you. Compare the result with a source statement that follows the same definition.

When to use this result

Use it during an overhead review or before increasing fixed capacity. Check whether stronger sales have covered the additional operating expense.

Check before you act

A one-off operating item can distort a period comparison. Record it separately before you attribute the change to day-to-day performance.

Example with the supplied inputs

Revenue: 100000; Operating profit: 18000. Result: 18.00%. The values are illustrative.

Compare one changed input

Revenue changes from 100000 to 110000. The result becomes 16.36%. All other inputs remain fixed.

Calculation rule

Formula

Result = (([Operating profit]) ÷ ([Revenue])) × 100

Inputs and output

Example inputs and entry conventions
Input Example value Entry convention
Revenue 100000 Use revenue on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.
Operating profit 18000 Use operating profit on the currency and period basis shown by the formula. Keep gross amounts, net amounts and unit amounts distinct; the page does not fetch a price or exchange rate.

Output: 18.00% is the example result. Operating profit separates the operating result from financing and other non-operating items. Keep the classification consistent between periods. Use the formula to distinguish a cash amount, count, percentage or ratio.

How to use the page

STEP 01

Collect the inputs

Gather Revenue, Operating profit. Use one period and the units shown in the form.

STEP 02

Run the calculation

Enter the values and select the action. The calculation rule above explains how the inputs produce the result.

STEP 03

Compare a scenario

Change Revenue on its own, keeping the other inputs fixed. Read both results before changing another assumption.

Worked example

With the example inputs listed above, the result is 18.00%.

Change Revenue from 100000 to 110000 while keeping every other value fixed. The result becomes 16.36%. This comparison isolates that input; it does not forecast how other variables will respond.

Check the stated formula, units and limits before using the result in a decision.

Calculation and source notes

Keep the displayed formula, input units and model scope with the result. Corrections or questions can be sent through the request section on this page.
