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 $4,320 and cash costs plus equipment reserve are $950. That leaves $3,370 for the owner before tax.
The scenario uses about 84.0 owner hours per month. Valuing those hours at $25 leaves $1,270 in monthly profit after owner time. This illustrates the formula; it is not an earnings forecast.
Make the estimate fit your work
Use total person-hours: two cleaners working two hours use four labor-hours. The owner-hours field is for your time only; add employee wages and payroll burden to paid labor. Include laundry and key pickup in time estimates.
