Idea PlannerMonthly profit and break-even worksheet
Type the numbers you have found in your test. See the profit, the break-even sales and what a slow month does.
These numbers are examples. Use numbers from your own test of the idea, not hopes.
How the numbers are worked out
- Sales a month = sales a day x days open.
- Left after the cost of what you sell = sales x (price minus cost per sale).
- Profit before your pay = that figure minus fixed costs and the loan instalment.
- Break-even sales = (fixed costs + instalment) / (price minus cost per sale).
Test the plan with 70 percent of your sales figure to see the business in a slow month. If it loses money, find a way to cut fixed costs or raise the price before you start. For prices see the freelance rate calculator and the seller profit calculators.
Common questions
Where do I get "sales a day"?
From your small test and from watching similar places. Count customers for a week. Do not use a guess you want to be true.
Is my own pay a cost?
Yes. Count it, or you will think the business earns more than it does.
