StepShown answer

How do I calculate a sustainable freelance hourly rate?

Start with the pay and business money you need. Then divide by the hours clients will actually pay for.

Direct answer

Add your yearly personal pay goal and yearly business costs. Increase that total if part of the money collected must stay in the business. Then divide by realistic paid client hours and the share of invoices you expect clients to pay. Do not divide by every work hour. Time spent finding clients, doing office work, and taking time off is not paid client time.

What matters most

Start with the yearly amount the business must provide.
Separate all work time from time a client pays for.
Allow for time off and invoices that may never be paid.
Check whether clients will pay the rate and whether the work can be completed on time.

Find the yearly money needed

Personal pay and business costs both use the money clients pay. Add them before finding the rate. If some collected money must stay in the business, increase the amount that must be billed. Otherwise, the same money may be promised twice.

Taxes are not included here. A pay goal before taxes stays a before tax goal unless you add a qualified tax estimate outside this tool.

Use paid client hours, not every work hour

Start with the weeks you will work after time off. Multiply by realistic paid client hours each week. Do not use every hour at your desk. Finding clients, writing proposals, bookkeeping, learning, and unpaid changes still take time.

Then allow for invoices that may not be paid. If the plan treats every invoice as cash, the rate can look workable even when the cash is not there.

Check whether the result works in real life

Compare the needed rate with your current rate and a typical project price. Include all hours the project really takes. A rate can work in the math but still be hard to sell. A rate that clients accept can still lose money.

If the result feels unrealistic, change a real part of the plan. You might change the work included, the clients served, paid hours, costs, or pay goal. Do not hide the gap.
