How the calculation works
Monthly revenue = jobs or stops × average price. Monthly cash costs = volume × (supplies + travel + equipment reserve) + paid labor + overhead.
Owner earnings = revenue − cash costs and equipment reserve. Owner-time allowance = owner hours × hourly value. Profit after owner time = owner earnings − that allowance.
Break-even volume = fixed monthly costs ÷ contribution per job or customer after owner time, rounded up. Startup recovery = cash startup investment ÷ monthly profit after owner time. N/A means the available contribution or profit is not positive.
Worked example
With the original defaults, monthly revenue is $3,980 and cash costs plus equipment reserve are $1,400. That leaves $2,580 for the owner before tax.
The scenario uses about 50.0 owner hours per month. Valuing those hours at $25 leaves $1,330 in monthly profit after owner time. This illustrates the formula; it is not an earnings forecast.
Make the estimate fit your work
Do not multiply the ticket by the number of rooms again. The average ticket already covers the whole job. Account for spot treatment, furniture moving, drying equipment and wastewater handling in your own costs.
