Massage Practice Overhead Calculator
Calculate monthly business costs for a solo massage therapy practice.
About this calculator
This calculator treats Monthly Overhead as the straight sum of eight monthly cost inputs -- Rent / Space, Utilities, Liability Insurance, Massage Supplies, Linens & Laundry, Marketing, Software / Booking, and License / CEU Fees -- with no weighting or category caps (line 6). Every dollar you enter in any of those fields adds one dollar to Monthly Overhead, so Annual Overhead is simply that total multiplied by twelve (line 7). Daily Overhead divides the same monthly figure by twenty-two, reflecting a fixed assumption of twenty-two working days per month rather than calendar days (line 10).
Overhead per Session goes one step further and spreads Monthly Overhead across eighty-eight sessions -- a baked-in capacity of four sessions per day across those same twenty-two days (lines 13-14). Min Hourly Rate Needed is the only output that adds something beyond your entered costs: it sums Monthly Overhead with a hard-coded four-thousand-dollar desired take-home baseline, then divides by one hundred thirty-two working hours per month, computed as twenty-two days times six hours per day (lines 17-19). None of the eight cost inputs influence session count or hours worked -- they only feed the shared monthly total that every derived figure scales from.

How to Use This Calculator
- Enter all monthly fixed costs: rent, insurance, licensing, software, and loan payments.
- Input monthly variable costs: supplies (oils, sheets, lotions), utilities at variable rates.
- Set the number of massage sessions per month and average session revenue.
- Review the overhead cost per session and the break-even session count.
- If overhead per session exceeds 40% of session revenue, identify the largest cost centers to reduce.

Frequently Asked Questions
Why does changing Rent / Space move Min Hourly Rate Needed even though I never entered a take-home goal?
Min Hourly Rate Needed always adds a fixed four-thousand-dollar desired take-home baseline on top of whatever Monthly Overhead your eight cost inputs produce, then divides that combined figure by one hundred thirty-two working hours per month -- twenty-two days at six hours each (lines 17-19). Raising Rent / Space increases Monthly Overhead directly through the sum on line 6, so the hourly figure rises even though the take-home target itself never changes.
How does the calculator get Overhead per Session from my monthly costs?
Overhead per Session divides your total Monthly Overhead -- the sum of all eight monthly cost fields -- by eighty-eight, a fixed session count baked into the engine as four sessions per day across twenty-two working days per month (lines 13-14). Your inputs never ask how many sessions you actually book; the per-session figure always assumes that full eighty-eight-session capacity.
Do all eight cost categories contribute equally to Monthly Overhead?
Yes. Monthly Overhead is a plain addition of Rent / Space, Utilities, Liability Insurance, Massage Supplies, Linens & Laundry, Marketing, Software / Booking, and License / CEU Fees with no multipliers, caps, or category weighting (line 6). A fifty-dollar increase in Marketing moves Monthly Overhead by exactly the same amount as a fifty-dollar increase in Rent / Space, and Annual Overhead, Daily Overhead, and Overhead per Session all scale from that single summed total.
Why is Daily Overhead divided by twenty-two rather than thirty calendar days?
Daily Overhead divides Monthly Overhead by twenty-two, matching the same working-day assumption used elsewhere in the engine for session capacity and hourly-rate math (lines 10 and 18). The calculator models business overhead spread across working days only, not across every day of the calendar month, so weekends and non-booking days are excluded from that daily figure.
