Tattoo Shop Overhead Calculator

Monthly Overhead is computed only from Monthly Rent, Utilities, Insurance, Licensing / Permits, Marketing / Advertising, and Supplies & Consumables (lines 6-7). Number of Artists and Avg Revenue per Artist feed total shop revenue for profit and overhead-percentage math (lines 10-12) but are never added, subtracted, or divided into the cost total itself.

Break-Even Revenue is set equal to total monthly cost with no additional markup or buffer -- it is literally the same summed overhead figure, rounded for display (line 15). Monthly Overhead is that cost total under its primary label (line 7). The two outputs report the same underlying number; Break-Even Revenue names the revenue level needed to cover those costs.

Cost per Artist divides total monthly overhead by Number of Artists when the count is greater than zero, otherwise it reports the full overhead as if one artist carried it (line 14). Adding artists spreads the same fixed monthly cost pool across more people, so Cost per Artist falls as headcount rises even when Monthly Overhead stays constant.

Daily Overhead divides total monthly cost by twenty-six, a fixed working-day assumption baked into the engine (line 18). That figure spreads your summed rent, utilities, insurance, licensing, marketing, and supply costs across twenty-six studio working days rather than calendar-month days or artist schedules.
