Strong target
Above the planning range we use for general small business
To cover $12,000 in fixed costs and still keep $8,000 in monthly profit, you need about 173.9 sales and $31,304 in monthly revenue.
If that goal feels heavy, raise average selling price per sale, lower direct cost per sale, or trim fixed overhead. Each change reduces the number of sales you need.
Planning guide
This calculator compares your target profit margin with a simple planning range for each industry.
The input labels also change by industry, so you can work in orders, bookings, appointments, jobs, or engagements instead of one generic sale model.
Use this if none of the listed industries fit, or if you want a broad planning check first.
Benchmark range: 10% to 20%

Calculator guide
This calculator helps you work backward from the profit you want to keep each month. It adjusts the unit language by industry, then shows the volume and revenue needed to get there.
Many owners stop at break-even. That is not enough. You also need to know what it takes to keep real profit after costs.
This calculator adds your profit goal on top of fixed costs, then shows the orders, bookings, appointments, jobs, or engagements needed to support both.
Use the average selling value for your normal unit of work. For example, that might be an order, a room booking, a salon appointment, or a service job.
Then use the direct cost tied to that same unit. If the result feels too high, check price, direct cost, and fixed overhead before you assume demand is the main problem.
