Cost Accounting

Break-even volume

How many units cover the cost of keeping the lights on?

Every sale contributes its price minus variable cost toward fixed costs.

Break-even units = fixed cost ÷ (unit price − variable cost)
Every unit contributes its price less variable cost. ₹60,000 ÷ (₹500 − ₹300) = 300 units. If contribution is zero or negative, more units cannot cover positive fixed costs.
₹60,000 fixed cost, ₹500 price and ₹300 variable cost give 300 units.
Every unit contributes its price less variable cost. ₹60,000 ÷ (₹500 − ₹300) = 300 units. If contribution is zero or negative, more units cannot cover positive fixed costs.

Variable cost rises to ₹350. How many units now break even?
