Use the calculator below to estimate your weekly, monthly and yearly income based on lesson price, lessons per week, and weeks worked. Then track it automatically in InstructorOS (plus expenses, profit and tax estimates).

Enter your typical schedule and lesson price. We’ll estimate turnover and show a simple hours breakdown.
Tip: 46 weeks/year = 6 weeks off (holidays, sick days, downtime).
Mock tests, theory sessions, add-ons — anything not counted in standard lessons.
Turnover is step one. To see what you’ll actually keep, track expenses and use the tax estimator.
Because “I think I’m doing alright” isn’t a number. Turnover gives you clarity — then you can plan fuel, repairs, quiet weeks, and how much to set aside.
See how many lessons you need per week to hit a target turnover.
Quickly compare £30 vs £35 vs £40 and see the yearly difference.
Weeks off matter. This calculator makes the impact obvious.
Once turnover is clear, expenses + tax planning becomes simple.
