FAQ
How does the consulting day rate calculator work?
Consultants don't bill 250 days a year. Back out holidays, admin, and sales time, then add overhead and profit to get a rate that actually works. The underlying maths is: Day rate = (target income + costs) ÷ billable days
What do I need to enter?
5 values: target annual income, annual business costs, working weeks per year, billable days per week, and profit buffer. Each field starts with a sensible default, so you can change one number at a time and watch the result move.
What does the day rate to charge result mean?
It is returned as a money amount in US dollars and updates live as you edit the inputs, so you can compare two or three versions of a scenario in a few seconds.
Is this calculator free, and do I need an account?
Yes, it's free, and no account is required. Nothing you type is stored on our servers — the maths runs entirely in your browser.
How accurate is the result?
It applies the standard formula exactly, so the arithmetic is precise. Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
Who is this tool for?
It's built for anyone comparing money scenarios before committing — budgeting a payment, sanity-checking a quote, or seeing what a change in rate or term actually costs.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
