How this calculator works
Sale price = list × (1 − discount); margin = (sale price − cost) ÷ sale price
- volume needed
- the sales increase required to keep total profit unchanged
Important considerations
- Frequent discounting trains customers to wait for the sale.
- A 20% discount on a 40% margin needs a 100% volume increase to break even.

Frequently asked questions
Why do small discounts hurt so much?
The discount comes entirely out of profit, not revenue, so the percentage effect on margin is much larger.
