Calculate annual profit from revenue and expenses entered weekly, biweekly, monthly, quarterly, or yearly, plus other income and one-time costs.
Annual Profit Formula
The calculator converts your revenue and expense entries to annual amounts, then subtracts to find profit. It also calculates margin and break-even values from the same inputs.
Annual Profit = (Revenue * P_r) + Other Income - (Expenses * P_e) - One-Time Costs
Profit Margin = (Annual Profit / Annual Revenue) * 100
Break-Even Monthly Revenue = Annual Expenses / 12
- Revenue: income amount entered for the selected period.
- Expenses: recurring costs entered for the selected period.
- P_r, P_e: period multiplier (52 weekly, 26 biweekly, 12 monthly, 4 quarterly, 1 annual).
- Other Income: extra annual income such as interest or refunds.
- One-Time Costs: yearly non-recurring costs like equipment or repairs.
The calculator multiplies your revenue and expense entries by the period factor, adds the optional annual extras, and returns annual, monthly, weekly, and daily profit. The margin shows what share of revenue you keep, and the break-even monthly revenue shows the minimum monthly income needed to cover annual expenses.
Reference Tables
Use these tables to interpret your result and to convert period entries quickly.
| Profit Margin | Interpretation |
|---|---|
| Below 0% | Loss. Expenses exceed revenue. |
| 0% to 5% | Thin margin. Vulnerable to cost shifts. |
| 5% to 10% | Low margin. Common for retail and food service. |
| 10% to 20% | Moderate margin. Healthy for most small businesses. |
| Above 20% | Strong margin. Typical of software and professional services. |
| Period | Multiplier to Annual |
|---|---|
| Weekly | x 52 |
| Biweekly | x 26 |
| Monthly | x 12 |
| Quarterly | x 4 |
| Annual | x 1 |
Example Problems
Example 1. A small shop earns $12,000 in monthly revenue and pays $8,500 in monthly expenses. There is no other income or one-time cost. Annual revenue is $144,000 and annual expenses are $102,000. Annual profit is $42,000. Profit margin is 29.17%.
Example 2. A freelancer earns $2,000 weekly and pays $600 weekly. Other annual income is $1,500 from interest. One-time costs are $4,000 for a new laptop. Annual revenue is (2,000 x 52) + 1,500 = $105,500. Annual expenses are (600 x 52) + 4,000 = $35,200. Annual profit is $70,300. Profit margin is 66.64%.
FAQ
Does this calculate net profit or gross profit? It calculates net profit relative to the costs you enter. If you only enter cost of goods sold, the result is gross profit. If you include all operating expenses, the result is operating or net profit.
Should I include taxes in expenses? Include them if you want after-tax profit. Leave them out for pre-tax profit. Be consistent across periods.
What is the break-even monthly revenue? It is the monthly revenue needed to cover your annual expenses. Earn more than this each month and you turn a profit for the year.
Why is my margin negative? Annual expenses plus one-time costs are higher than annual revenue plus other income. Reduce costs or raise revenue to move above zero.
