Small Business Profit Assistant
Sales look good, but is the business making money? Count every cost, including your own salary and money stuck in udhaar, and see what moves profit most.
QUICK ANSWERNet profit = sales × (1 − purchase cost % − variable cost %) − fixed expenses − interest cost of credit sales. Break-even sales = fixed expenses ÷ contribution margin. A 3% price rise or 2% cheaper purchase usually adds more profit than 10% more sales.
