Short answers for the questions people usually have before trying a utility like this.
Yes. It is completely free, with no sign-up, no watermark, and no usage limits.
No. Amounts are currency-neutral and use the same unit across all inputs, so it works in any country.
Profit = (selling price − unit cost) × units − fixed costs. Selling 500 units at $20 that cost $12 each, with $1,000 of fixed costs, leaves $3,000 profit.
Fixed costs ÷ profit per unit. $1,000 ÷ $8 = 125 units; every unit after that adds $8 of profit.
