Quick answer: Break-even Calculator
Break-even units = fixed costs / (price per unit - variable cost per unit). The contribution margin must be positive or the product cannot break even.
Example: GBP 6,000 fixed costs with GBP 12 price and GBP 7 variable cost needs 1,200 units to break even.
Calculations follow the documented formula on this page; rounding and input units can change the last digit—treat outputs as educational estimates unless you reconcile with source systems.
* This is an estimate. Actual amounts may vary slightly based on input assumptions.
What this calculator does
- Break-even Calculator
- Find break-even units and revenue.
Break-even ignores timing of cash - rent is due monthly even if units sell unevenly. Still, it’s the fastest “is this priced sanely?” gut check for a new SKU.
Business planning tool for pricing strategy.
Inputs on this page: Fixed Cost, Price per Unit, Variable Cost/Unit. Assumptions stay visible so you can reproduce the figure elsewhere.
When to use it
- Use Break-even Calculator when you need a transparent break even answer before you commit numbers to a spreadsheet, invoice, or conversation.
- Reach for it when you already know (or can estimate) Fixed Cost and want the dependent result without rebuilding the formula by hand.
- Skip it when you need certified advice, signed-off payroll, or a lender’s official quote—those require the primary institution’s systems.
Key takeaways
- Variable costs often creep - re-run when suppliers raise prices.
- Discounts shrink margin and push break-even volume up fast.
- Pair with cash runway; breaking even on paper can still miss payroll.

Common mistakes
- Putting fixed costs into variable cost double-counts expenses. Rent and salaried overhead usually belong in fixed costs; materials and per-sale processing fees usually belong in variable costs.
- Forgetting variable costs makes break-even look too easy. A product with a GBP 20 price and GBP 12 unit cost contributes only GBP 8 toward fixed costs.
- Using average price while running heavy discounts can understate the units needed. Model the actual net selling price after discounts and platform fees.
