Free tool for hourly freelancers
Hourly freelance invoice calculator
Add the work and expenses you plan to bill, then copy an itemized estimate or carry the lines into a Sundry invoice. Use the calculator without an account.
Build your estimate
Add a row for each task or hourly rate. Your entries stay in this browser tab.
Enter non-negative amounts with up to two decimal places.
Add discount or tax amount
Enter dollar amounts from your agreement or local tax rules. This tool does not determine what is taxable.
This is an estimate, not a sent invoice. Confirm rates, expenses, taxes, and payment terms before billing a client.
Example: two rates on one invoice
Suppose you billed 8.5 hours of design work at $75 per hour and 2 hours of revisions at $100 per hour. Your client also agreed to reimburse a $48 expense and receive a $25 discount. Enter each rate as a separate work row so the charges stay clear.
| Item | Calculation | Amount |
|---|---|---|
| Design work | 8.5 hours × $75 | $637.50 |
| Revisions | 2 hours × $100 | $200.00 |
| Agreed expense | — | $48.00 |
| Discount | — | −$25.00 |
| Estimated total before any tax | $860.50 | |
This example leaves out tax. If you need to add tax, enter the dollar amount after checking what applies to your invoice.
How to calculate your total
Multiply the hours by the rate for each task, then add those line totals. Add expenses your client agreed to reimburse, subtract any agreed dollar discount, and add any tax amount you determine applies. The calculator does not decide which charges are taxable.
Before you send it
- Check each task's hours, rate, and date against your time records.
- Describe each charge and keep receipts for reimbursable expenses.
- Confirm the due date, payment instructions, discount, and any tax before billing.
