Accountants Day Rate (Monthly) Calculator
Estimate the daily rate an accountant needs to charge each month to cover costs and reach a target take-home income.
Overview
This accountants day rate calculator estimates the daily fee needed to cover regular business costs and achieve a chosen monthly take-home income. Add your expected tax and pension percentages, then use a realistic number of billable days rather than all working days.
How it works
The calculator first works backwards from your desired take-home income. It estimates the profit needed before tax and pension contributions, adds your monthly business costs, and divides the resulting revenue target by your expected billable days. Fewer billable days, higher costs or a higher estimated tax rate will increase the day rate required.

Frequently asked questions
How is the accountant day rate calculated?
It adds your monthly business costs to the profit needed to reach your target take-home income, then divides that revenue target by your billable days per month.
What counts as a billable day?
A billable day is a day you can invoice to a client. It normally excludes annual leave, sick days, sales activity, administration, training and other non-client work.
Should I include VAT in my day rate?
This calculator excludes VAT. If you are required to charge VAT, it is normally added to your client invoice separately rather than treated as your income.
Why is my required day rate higher than my take-home income suggests?
Your day rate must also fund business costs, cover non-billable time and allow for tax and pension contributions. Only a portion of invoiced revenue becomes personal take-home income.
How many billable days should an accountant plan for each month?
This varies by client mix and workload. Using a cautious estimate, such as 12 to 18 days, can help allow for administration, marketing, leave and quieter periods.
Does this calculator work for contractors as well as accountants?
Yes. The same approach can help any self-employed professional estimate a day rate, provided the tax and cost assumptions are adjusted to their situation.
