Business Break Even Units Calculator (30 Years)

Find how many units must be sold to break even. This business version uses a 30-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 30 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 30 years means 16.67 a year, which is 1.39 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 30-year term suits only a business tied to a very long asset, for example a maker of building components with a 30-year service life, or a business linked to a long commercial lease. At 16.67 units a year the pace is so slow that it hides the real risk: the product, the buyer and the price are all likely to change several times before 500 units are sold.

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.

Is a 30-year term normal for a business break-even plan?
No, for most products it is far longer than a realistic product life. A 30-year figure is useful only as a lifetime warning, showing how slow sales can still reach 500 units in total, not as a plan to follow year by year. Most businesses should judge a product over 5 to 10 years and then decide whether to continue.

How can the risk of a 30-year plan be cut?
By setting review points, for example at years 5, 10 and 15, where the business checks actual sales against the pace of 16.67 units a year. If sales are behind pace at two reviews in a row, the business should change price, cut fixed costs, or stop the product, rather than waiting 30 years to find out it never broke even.

What is a business trading when it chooses 30 years over 5 years?
It trades urgency for patience, and patience for risk. Over 5 years the business must sell 100 units a year and learns quickly whether the product works. Over 30 years it needs only 16.67 units a year, but it also ties up its name, stock and attention for three decades on a product that may be obsolete long before the 500th unit sells.
