Business Break Even Units Calculator (35 Years)

Find how many units must be sold to break even. This business version uses a 35-year planning term as its starting point.

This Break even units result is the number of units that must be sold for revenue to exactly cover total costs, so selling fewer units means a loss and selling more units means a profit.

Formula

Break even units equal fixed costs divided by price minus variable cost per unit.

How it works

At break even, total revenue exactly covers total costs, with no profit and no loss.

Worked example

Fixed costs $10,000, price per unit $50, variable cost per unit $30, term 35 years. First, the contribution per unit is $50 minus $30, which is $20. Break even units are $10,000 divided by $20, which is 500 units. At 500 units, revenue is 500 times $50, which is $25,000, variable costs are 500 times $30, which is $15,000, and total costs are $15,000 plus $10,000, which is $25,000, so revenue exactly covers costs. As a planning pace only, not as an output of this calculator, reaching 500 units over 35 years means 14.29 a year, which is 1.19 a month. Selling 100 units more, 600 units in total, gives revenue of $30,000 against total costs of $28,000, so the profit is $2,000, because each extra unit adds $20.

Who this term suits for a business: A 35-year term suits, at most, a multi-generation family firm with a stable, long-life product, for example a maker of heritage building materials or a specialist supplier to a protected trade. Even then, at 14.29 units a year the plan is fragile: one change in regulation, materials or the main buyer can end the product, and the remaining units may never sell.

FAQs

What is break even?
Break even is the point where revenue covers all costs, so profit is zero.

Is this business calculator exact?
No, it is an estimate for planning only, based on the numbers you enter.

Are these figures financial advice?
No, they are estimates for planning only, not financial advice. Check with a qualified adviser for decisions involving large sums.

Why does the pace fall only a little from 30 years to 35 years?
Because 500 units divided by more years always gives a smaller yearly pace, but the change gets smaller as the term grows. From 30 to 35 years the pace falls from 16.67 to 14.29 units a year, a drop of only 2.38 units, while the total to sell stays at 500 units. Stretching the term further buys very little extra safety each time.

Who should even consider a 35-year business term?
Almost no ordinary business should plan a single product over 35 years. The only honest cases are long-life, low-change products with a protected market, and even those need a successor, a spare-parts plan and a price review. For any fast-changing product, a 35-year break-even figure is a warning, not a target.

What must a business check before signing up to a very long product plan?
Whether its fixed costs, supplier, price and main buyer can plausibly last 35 years, and what happens if any one of them fails. It should also check the cost of holding stock, servicing old products and keeping skills alive for 35 years, because those hidden costs can exceed the $10,000 of fixed costs in this example.
