Free accounts calculator for small businesses and freelancers
Keeping on top of your numbers does not need a spreadsheet or accounting software. This free accounts calculator lets you enter your income and expenses for any period — a month, quarter, or year — and instantly shows your profit or loss and your net profit margin. It is perfect for sole traders, freelancers, and small business owners who want a quick, clear picture of how the business is doing.
How to use it
Enter your total sales and any other income, then fill in your main costs: stock or materials, wages or subcontractors, rent and bills, and anything else. The calculator adds up both sides and subtracts expenses from income to give your net profit (or loss). The profit margin shows what percentage of your income you actually keep — a key measure of how healthy the business is.
Why track profit and margin?
Revenue alone does not tell you whether a business is succeeding — profit does. A business can have high sales but make a loss if costs are too high. Watching your net profit margin over time helps you spot rising costs early, decide whether to raise prices, and plan for tax. To set prices that protect your margin, try our profit margin & markup calculator.
Keeping good records
Use this calculator alongside simple bookkeeping: keep receipts, record income and expenses regularly, and set aside money for tax. In the UK, sole traders report income through Self Assessment; in the US, the self-employed file a Schedule C. Good records make these far easier and ensure you claim all allowable expenses.
Frequently asked questions
Does this calculate my tax?
No. It shows your profit before tax. Your tax depends on your country, allowances, and other income. Use your profit figure as the starting point for working out what you owe.
What counts as an allowable expense?
Generally, costs incurred wholly for the business — stock, equipment, travel, premises, and professional fees. Rules vary by country, so check your local tax authority’s guidance.
