Accounting Operating Cost Calculator
Calculate your total operating costs, annual operating expenses, and operating cost ratio from regular business expenses.
Overview
This Accounting Operating Cost Calculator helps you total regular business expenses and compare them with monthly revenue. Enter payroll, premises, utilities, subscriptions, marketing, and other ongoing costs to estimate your operating cost ratio and monthly operating profit.
How it works
The calculator adds each monthly expense category to find your total monthly operating cost. It multiplies that amount by 12 to estimate annual operating costs. The operating cost ratio divides total monthly operating costs by monthly revenue, showing the proportion of revenue needed to cover the listed expenses. Monthly operating profit is revenue minus those operating costs; it does not include unentered costs, taxes, interest, or non-operating items.

Frequently asked questions
What are operating costs?
Operating costs are the recurring expenses needed to run a business day to day, such as payroll, rent, utilities, software, marketing, insurance, and supplies.
What is an operating cost ratio?
The operating cost ratio is total operating costs divided by revenue, expressed as a percentage. A lower ratio generally means less revenue is being used by the listed operating expenses.
Should payroll be included in operating costs?
Usually, yes. Regular employee wages, salaries, employer costs, and ongoing contractor payments are commonly treated as operating expenses.
Are taxes included in operating costs?
This calculator does not automatically include taxes. You can include recurring business taxes in other costs if that suits your internal reporting, but income taxes are often reviewed separately.
What costs should be excluded from this calculator?
Exclude irregular capital purchases and costs you want to analyse separately, such as loan principal repayments, investment spending, depreciation, interest, and one-off exceptional items.
Why is my operating profit different from my accounting profit?
Your accounting profit may include additional income, depreciation, interest, taxes, accruals, inventory changes, and expenses not entered here. This calculator is a simplified operating-cost estimate.
