Business Break Even Units Calculator (20 Years)

Find how many units must be sold to break even. This business version uses a 20-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 20 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 20 years means 25 a year, which is 2.08 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 20-year term suits a business with a very long contract or asset life, for example a supplier to schools or hospitals on rolling contracts, or a maker of long-life industrial parts. At 25 units a year the pace looks easy, which is the danger: a business can drift for years, sell slowly, and only discover late that its product has been superseded and the remaining units will never sell.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 break-even number stay at 500 units after 20 years?
Because the formula uses only fixed costs, price and variable cost, not time. Time only changes the planning pace, from 100 units a year over 5 years to 25 units a year over 20 years. A longer term does not make the product cheaper to break even on, it only spreads the same 500 units over more years.

Is a 20-year term suitable for a business with irregular orders?
Only if the business keeps a cash reserve for quiet years. At 25 units a year on average, one bad year of 5 units must be balanced by a good year of 45 units, and fixed costs still have to be paid in the bad year. Irregular orders need a buffer and a minimum annual order target, not just a 20-year average.

What should a business check about its product before a 20-year plan?
Whether the product, its materials and its main buyers will still exist in 20 years, and whether the $50 price can survive competition and inflation. If the product is likely to be replaced in 10 years, a 20-year break-even plan overstates its safe lifetime, and the business should plan an exit or a replacement product instead.
