Tutoring Business Revenue Calculator

This calculator builds a tutor's revenue from the ground up rather than just multiplying students by rate. It first converts your active student count and sessions-per-week into total weekly session slots, then splits that pool between 1-on-1 sessions and group sessions using your group-session percentage — group slots are converted into an actual group session count by dividing by average group size and rounding up, since a group session serves several students at once. Cancellations are applied separately to both session types before revenue is computed, so a higher cancellation rate lowers gross revenue and hours worked together. Group sessions are priced at 65% of your 1-on-1 hourly rate per student (a common discount structure), multiplied by group size, so a well-filled group session can out-earn an individual one even at a lower per-student rate.

Monthly figures multiply weekly gross revenue by the fixed conversion constant 4.33 — a standard average-weeks-per-month figure — and net income simply subtracts your entered monthly expenses. The effective hourly rate is the more honest number here: it divides net income by hours actually worked, but inflates those hours by 25% to account for prep, admin, and marketing time that doesn't show up as billable sessions — so it will read lower than your quoted rate, which is the point. Utilization compares that overhead-inclusive workload against a 40-hour week. Two fixed constants drive most of the uncertainty in the output: the 65% group discount and the flat 25% overhead figure; if your actual group pricing or admin burden differs meaningfully, treat the net and effective-rate outputs as directional rather than exact.
