Hourly and day rate calculator

Work out the minimum rate you need to charge to reach your target income, after business costs and tax.

Why billable hours matter most

Selling, admin, learning and invoicing all take time you can’t bill. If you plan on billing every working hour, your rate will be too low. Be realistic about how many hours a week clients will actually pay for.

From minimum rate to market rate

  • Check what similar specialists charge in your market.
  • Consider fixed fees or retainers for repeat work. See pricing models explained.
  • Review your rates at least once a year.

Frequently asked questions

Which tax rate should I use?
Use an estimate of the overall tax and social contributions on your profit where you live. An accountant can give you a more accurate figure.
Should I quote hourly or a day rate?
Hourly suits small or unpredictable tasks. Day rates suit consulting and project work. Fixed fees reward efficiency, if the scope is clear.
