How do I calculate what day rate I need as a freelancer or contractor?
The correct formula works backwards from your target net income. Add the income tax, PRSI or National Insurance, and USC you will owe on your earnings. Then add your annual business overheads: accounting fees, professional insurance, software, and equipment. Divide the resulting total revenue by your realistic number of billable days (working days minus public holidays, annual leave, sick days, and an allowance for gaps between contracts). The result is your required day rate. The calculator above does this automatically for Ireland and UK contractor structures.
