Home Break Even Units Calculator (15 Years)

Find how many units must be sold to break even. This home version uses a 15-year planning term as its starting point.

A result of 500.00 break even units means 500 units must be sold to cover the $10,000 fixed costs exactly, leaving no profit and no loss. Selling fewer than 500 units leaves part of the fixed costs uncovered, while each unit sold after the 500th moves the business into profit, because its $50 price exceeds its $30 variable cost. The 15-year term is a planning horizon only and does not change this 500-unit total.

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 15 years. First, the contribution per unit is $50 minus $30, which is $20. Using the page formula, break even units are $10,000 divided by $20, which is 500.00 units. That is the calculator's own result for these defaults, and it is the same on every page in this group because the term is not an input. At break even, revenue is 500 times $50, which is $25,000, variable costs are 500 times $30, which is $15,000, and $25,000 minus $15,000 minus $10,000 of fixed costs leaves zero profit, exactly as break even should.

As an illustration only, not the output of this page, spreading those 500 units evenly over 15 years is about 33.33 units a year. That is a planning average only, not a sales plan: home sales are seasonal, and quiet months do not reduce the fixed costs that must be covered.

Who this term suits for a home-based seller: a home woodworker selling cutting boards and small furniture from a garage workshop, checking whether a workbench, tools, and dust extraction pay for themselves before a bigger workshop upgrade.

FAQs

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

Is this home 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 500 units over 15 years too easy to be useful?
On its own, yes, if it is read as only 33.33 units a year. Its use is as a floor: it shows the minimum total that must sell before the home business has paid for itself, and any serious plan should aim well above that floor.

How should a home seller use a 15-year break even for a kitchen or workshop upgrade?
By treating the upgrade as a new fixed cost and recalculating: add the upgrade cost to the fixed costs, keep the price and variable cost the same, and check how many extra units the upgrade itself must sell before it pays.

What happens if fixed costs rise to $15,000 in a 15-year plan?
Break even rises to $15,000 divided by $20, which is 750 units. That is 250 more units than the worked example, which is why a bigger kitchen, new equipment, or higher insurance should never be added without redoing this calculation.
