Business Break Even Units Calculator (10 Years)

Find how many units must be sold to break even. This business version uses a 10-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 10 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 10 years means 50 a year, which is 4.17 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 10-year term suits an established small business planning one product line over a full decade, for example a furniture maker supplying hotels, a distributor with annual contracts, or a parts supplier with repeat business customers. At 50 units a year the pace is steady rather than urgent, which fits contract sales, but the business must still re-check its fixed costs and variable costs each year, because a supplier price rise would change the $20 contribution.

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 is 10 years a common middle choice for a business break-even plan?
Ten years is long enough for contract and repeat orders to build up, yet short enough that the product, price and costs are still recognisable. At 50 units a year, the business can judge the plan from annual sales without waiting a lifetime, and it can stop or change the product if sales fall behind in the first two or three years.

How should a business test whether 50 units a year is realistic?
Compare 50 units a year with actual orders from the last two years, not with a sales target. If the business already sells 40 units a year of a similar product, 50 is a stretch but plausible. If it has never sold more than 10 units a year, the plan needs new buyers, a new channel, or a lower fixed-cost base before it can be trusted.

What if fixed costs rise during the 10 years?
Every rise in fixed costs raises break even by the rise divided by $20. If fixed costs rise from $10,000 to $12,000, break even rises from 500 to 600 units. A 10-year plan should therefore include a fixed-cost review each year, and a price or cost decision, rather than assuming $10,000 stays fixed for a decade.
