Net profit = Total revenue - total expenses

1. Find total revenue. Add up all money your business earned from sales of goods or services during the year.
2. Subtract your expenses. Deduct all business costs like supplies, rent, utilities, software, contractor payments, and loan interest.

An estimate is fine, you don't need exact figures.

Don't count yourself (even if you pay yourself a salary) or 1099 contractors and freelancers.
