Frequently asked questions
How do I calculate my day rate as a contractor?
To calculate a fair day rate, start with your desired annual income, then divide by the number of truly billable days in a year. Subtract weekends, public holidays (8 in England), any annual leave you plan to take, and non-billable days for admin, training, and business development. Most contractors end up with 200–230 billable days per year.
Why should I account for non-billable days?
As a self-employed tradesperson or contractor, you only get paid for the hours you bill a client. Days spent quoting, chasing invoices, doing admin, dealing with illness, or handling training are days you're not earning. If you set your rate based on 260 working days but only bill 220, you'll under-earn by over 15%.
How many working days are there in a year in the UK?
There are roughly 260 working days in a year (52 weeks × 5 days). After deducting the 8 UK bank holidays, you have around 252 days. Taking 25 days of annual leave and 15 non-billable admin days leaves approximately 212 billable days — a sensible baseline for most contractors.
Should my day rate include VAT?
If you are VAT-registered, you charge VAT on top of your day rate. Quote your net day rate to clients and add VAT on your invoice. Use our VAT Calculator to work out the gross amount to put on your invoice.
