Changing your price shifts your break-even point immediately — a common mistake is adjusting price without recalculating how many units you now need to sell to cover costs.
Why break-even moves with price
Break-even volume = Fixed costs divided by (Price minus variable cost per unit). Raise the price and, all else equal, you need fewer units to break even. Lower it, and you need more.
A practical example
If fixed costs are $10,000 and your margin per unit rises from $20 to $25 after a price increase, break-even drops from 500 units to 400 — a meaningful cushion, or a meaningful risk if the price change goes the other way.
Recalculate before, not after
Run the new break-even number before finalizing a price change, not after you’ve already committed — it tells you whether the new price is realistic given your actual sales volume, not just whether it feels right.
