Discount, Margin & Break-Even Calculator
Enter your regular price, unit cost and discount to see the margin you keep after the markdown — and exactly how many more units the sale has to move just to break even. Then compare that cost to adding a deadline instead.
Your product
The markdown
Your starting margin is $48.00 per unit (60%). Every point of discount comes straight off that profit — not off the price the customer sees.
After the discount
Profit per unit
You'd need +71% more units just to stand still
Questions
Why do I need to sell so many more units just to break even?＋
A discount comes straight off your profit, not your revenue. If a 25% price cut halves your per-unit margin, you have to sell twice as many units to make the same total profit. This calculator shows the exact 'extra volume needed' multiple so you can see whether a flash sale is likely to clear that bar — most don't.
What happens when a discount is deeper than my margin?＋
If the sale price drops below your unit cost, your margin goes negative and you lose money on every unit — no amount of extra volume can break even. The calculator flags this with a warning so you catch it before you launch the promotion.
How is a countdown timer a cheaper alternative to a deep discount?＋
Discounting buys urgency by permanently giving away margin on every order. A countdown deadline creates the same 'buy now' pressure — a visible, ticking window — without touching your price. You keep full margin and still compress the decision, which is why timers so often beat a bigger markdown on net profit.
Now make the urgency actually tick.
