Business Break Even Units Calculator (25 Years)

Find how many units must be sold to break even. This business version uses a 25-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 25 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 25 years means 20 a year, which is 1.67 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 25-year term suits a family business or a long-standing brand planning across a generation, for example a regional food producer, a craft manufacturer, or a business passing from one owner to the next. At 20 units a year the plan depends on the brand surviving ownership changes, supplier changes and shifts in taste, so it needs a successor plan, not just a sales pace.

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 a 25-year break-even figure need a succession plan?
Because 25 years is longer than most owners, managers and sales channels stay unchanged. If the business changes hands in year 12, the new owner inherits the remaining units to sell, the same fixed costs, and possibly different prices. Without a handover plan, the 500-unit total can stall halfway through the term.

How does a business keep a 25-year plan realistic through market changes?
By treating 500 units as a lifetime target and reviewing price, variable cost and fixed costs at least every three years. If variable costs rise from $30 to $35, contribution falls to $15 and break even rises to 667 units, so the old 500-unit target is no longer enough and the plan must be reset.

What exit plan should a 25-year seller have?
A clear point at which to stop the product if sales fall behind pace for three years in a row, and a way to sell remaining stock without a large loss. A 25-year plan without an exit rule can keep a losing product alive long after its market has gone, tying up cash that a new product could use.
