Why this matters
A price increase can improve contribution even if some volume is lost, but the decision should be based on contribution retained—not fear of losing any customer. This calculator supports the decision about the new contribution per sale and the maximum volume loss the business can absorb while preserving current contribution. It is designed to expose the economic relationship among price, cost, volume and contribution before management relies on revenue growth alone.
Use current price, variable cost, proposed increase and reliable current sales volume. Keep cost definitions consistent: a variable cost should change with the unit or job, while fixed costs belong to the selected period. Pricing guidance uses contribution and managerial-accounting relationships. GAAP and IFRS do not prescribe a selling price or a universal break-even threshold. Financial-reporting standards govern recognition and presentation; they do not guarantee that a quoted price is commercially sustainable.
How to act on the result
- Segment customers instead of applying one increase blindly
- Communicate the value, effective date and any grandfathering rule clearly
- Measure retained contribution after the change, including discounts used to resist the increase
Run at least three scenarios: current conditions, a realistic improvement and a downside case. Check whether the required volume fits practical capacity and whether the market will accept the price. The goal is not to produce a perfect percentage; it is to make the trade-off visible before a discount, quote or expansion commits cash.
Common mistakes and limits
Watch for assuming variable cost stays unchanged, ignoring contract notice terms, raising price without fixing service problems and judging success only by units sold. Results exclude taxes, financing structure and complex cost behavior unless the inputs expressly include them. They are managerial estimates, not audited profit measures or GAAP/IFRS accounting policies. For regulated prices, long-term contracts or dominant customers, confirm legal and commercial restrictions before implementation.
What this calculator answers
How much sales volume could decline before a price increase reduces profit?
Formula and assumptions
Current contribution = current price − variable cost. New contribution = price after increase − variable cost. Required volume = current total contribution ÷ new contribution.
The result is an estimate. It is only as reliable as the inputs, and it does not account for every tax, legal, financing or operational consequence.
Worked-example method
Use the prefilled sample values, calculate once, then replace every input with numbers from your records. The result will show a risk level, key measurements and one recommended next move.
How to interpret the result
- Low: no immediate gap or the entered position is comparatively protected.
- Medium: manageable pressure exists, but it should receive a dated correction plan.
- High: the problem can materially damage cash or operations and requires near-term action.
- Critical: the entered assumptions indicate immediate loss, shortage or survival risk.

Frequently asked questions
What does this calculator tell me?
How much sales volume could decline before a price increase reduces profit?
How is the result calculated?
Current contribution = current price − variable cost. New contribution = price after increase − variable cost. Required volume = current total contribution ÷ new contribution.
Should I make a major decision from this result alone?
No. Use the result to identify and quantify a problem, then verify the underlying records, assumptions and local legal or accounting requirements.
