What if wastage changed?
Move the slider to see how a different wastage rate changes the true cost per sold unit, keeping your purchase cost and target margin the same.
How to use
- Enter the quantity you purchased, the total cost, how much spoiled, and how much actually sold.
- Enter your target margin to see the selling price you need per unit.
- Use the what-if slider to see how small changes in wastage move your true cost.
Note: True cost per sold unit = total purchase cost / quantity sold. This is an estimate — it does not include rent, labor or transport costs.
Tips
- Order smaller quantities more often for highly perishable items — freshness beats bulk discounts.
- Track wastage daily for one week; most shops are surprised by how high the real rate is.
- Price from the true cost, not the purchase price — otherwise wastage quietly erases your profit.
