Price Increase Calculator
Raising prices almost always beats cutting costs, but only if you know your breakeven. Enter your numbers to see the profit impact of an increase and the maximum volume you can lose before the rise stops paying for itself.

A price increase drops almost entirely to the bottom line, because the extra revenue carries no additional variable cost. Selling more units, by contrast, brings its own cost of goods with it. That asymmetry is why a 10% price rise usually improves profit far more than a 10% volume rise — and why the volume you can afford to lose is often much larger than owners expect.
The lower your margin, the more true this becomes. At a 40% contribution margin, a 10% price rise lets you lose a fifth of your customers and break even. At a 20% margin, the same rise lets you lose a third. Thin-margin businesses have the most to gain from pricing and are usually the most afraid to touch it.
What the Breakeven Number Does and Doesn't Tell You
The calculation assumes variable cost per unit stays flat and that fixed costs don't move. Both usually hold for a modest increase. What it cannot tell you is how many customers will actually leave — that depends on how differentiated you are, what switching costs your customers face, and whether competitors follow.
What it does give you is the size of the bet. If you can lose 20% of your base and still be ahead, and you believe realistic churn from a price rise is 5%, the decision is straightforward. If breakeven churn is 4% and you have no differentiation, it isn't.
How to Actually Implement It
- Segment first. New customers, then renewals, then your most price-sensitive accounts last, if at all. You rarely need to move everyone at once.
- Give notice and a reason. Input costs, service improvements, or simply that prices haven't moved in three years. Silence invites the assumption that you are opportunistic.
- Grandfather selectively. Holding your largest or longest-standing accounts at the old price for a defined period costs less than losing them and buys goodwill.
- Measure churn against this breakeven, not against zero. Some churn is the plan working, not the plan failing.
Frequently Asked Questions
How much can I raise prices without losing customers?
No calculator can answer that — it depends on your differentiation and your market. What this tool gives you is the breakeven: how much volume you could lose before the rise stops being worth it. Compare that number against realistic churn to size the risk.
Should I raise prices across the board or by segment?
Segment where you can. New customers absorb increases most easily, renewals next, and your most price-sensitive accounts last. A blanket increase is simpler to administer but concentrates the churn risk into one moment.
What if my variable costs rise at the same time?
Then update the variable cost field first and see where your margin actually sits before applying the increase. A price rise that only offsets a cost rise keeps you level rather than moving you forward — worth knowing which one you are doing.
Does this work for service businesses?
Yes. Use your hourly or project rate as the price and your direct delivery cost — staff time, subcontractors, materials — as the variable cost. Fixed costs are your overhead.
