Break-Even Calculator

Q = FC ÷ (P − VC): how many units cover the fixed costs. Optionally enter a quantity to read profit at that volume.

Break-even inputs

Result

Q =2,000.00
PFT =0.00

Worked example (T12): FC=20000, VC=8, P=18 → Q = 2,000.

Worked example — 2,000 units (T12)

Fixed cost 20,000, variable cost 8 per unit, price 18: each unit contributes 10, so the break-even quantity is 2,000 units. Below it you lose money; every unit above adds 10 of profit.

Frequently asked questions

What if P equals VC?

Contribution per unit is zero — no quantity ever covers fixed costs. The calculator (and the worksheet) report Error 5.

Where is this on the BA II Plus?

The break-even worksheet (2ND 6 on our keyboard; on the BA II Plus Professional it is the PROFIT worksheet) stores FC, VC, P and solves Q.
