Many freelancers undercharge because they forget to account for taxes, unbillable hours, and business expenses. This calculator tells you exactly what to charge.
A freelancer earning $80K gross actually needs to charge much more when factoring in 15.3% SE tax, business expenses, and the fact that only ~70% of hours are billable.
The formula: Rate = (Target Income + Expenses) / (Working Weeks × Hours/Week × Billable%)
Use this calculator before making any financial commitment that depends on this type of calculation. Running the numbers in advance lets you evaluate options without the pressure of a live negotiation or decision deadline.
Many financial calculation errors stem from omitting ancillary costs: fees, taxes, insurance, or maintenance. The headline figure (interest rate, monthly payment) is rarely the complete cost of a financial product.
An employee receives a counter-offer from another employer: a £4,000 salary increase but no pension contribution versus the current role's lower salary with 8% employer pension. Running both through the finance calculator shows the true net financial value of each offer.
Hours you can directly charge clients. Admin, marketing, and prospecting time is typically non-billable.
Multiply your hourly rate by 8 hours. Add a 10% premium for day rate bookings.
