Nail Service Pricing Calculator

The engine first computes an exact calculated price from direct cost divided by one minus combined overhead and profit percentages, with the denominator floored at 0.1 (lines 23-25). Menu price then applies ceiling division by five and multiplies back by five (line 28). That step produces clean menu-board numbers while overhead and profit dollars are recomputed from the rounded price rather than the exact figure (lines 31-33).

Labor cost multiplies service minutes divided by sixty by target hourly rate (line 16), and direct cost adds supply cost to that labor total (line 19). Both the exact calculated price and menu price flow from direct cost through the overhead and profit margin divisor (lines 23-28), so longer appointments raise labor, direct cost, and typically the recommended menu price together.

Supply cost enters direct cost and therefore the exact calculated price (lines 19, 25). Menu price, however, rounds the exact figure up to the nearest five dollars (line 28). Small supply-cost changes can shift the exact price without crossing the next five- dollar step, leaving menu price, overhead dollars, and profit dollars unchanged at the rounded level.

The engine adds ten minutes of turnover to service time to get effective minutes per appointment (line 37), divides sixty by that total for services per hour (line 38), then multiplies by menu price (line 39). That models back-to-back clients with a short buffer rather than assuming the full hour is billable service time alone.

Break-even clients per day uses a hard-coded two-hundred-dollar daily fixed cost (line 42), divides it by profit per service at the rounded menu price (lines 43-44), and rounds up. Profit per service itself comes from menu price minus direct cost minus overhead allocation at that menu price (lines 31-32). The break-even figure therefore reflects that fixed daily overhead assumption, not your entered overhead percentage alone.
