Business Expense Calculator
Estimate your monthly and annual business expenses, then compare expenses with revenue for a simple planning ratio.
This is a planning calculator, not accounting or tax advice. Expense categories and tax treatment vary by business and jurisdiction; use your actual records for bookkeeping and tax reporting.
What this calculator shows
Enter typical monthly spending by category. The calculator totals those costs, estimates the annual amount by multiplying the monthly total by 12, and—if you enter revenue—shows expenses as a percentage of monthly revenue.
What counts as a business expense?
Common business costs can include software, contractors, marketing, office supplies, travel, payment fees, professional services, equipment, and other costs connected to running the business. Whether a cost is deductible is a separate question governed by the rules that apply to you.
How to use the result
- Use recent statements or bookkeeping records to estimate normal monthly spending.
- Separate recurring operating costs from one-off purchases where useful.
- Compare expenses with revenue when reviewing pricing and profitability.
- Review the categories regularly so your budget reflects actual spending.
