Shop Break Even Units Calculator (30 Years)

Find how many units must be sold to break even. This shop version uses a 30-year planning term as its starting point.

The Break even units figure is the number of units that must be sold for revenue to cover all costs exactly, so selling fewer units means a loss and selling more units means a profit, and for the default figures 500.00 units is that turning point, which averages about 16.67 units a year over 30 years as a planning average only.

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. 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. Spread evenly over 30 years, that is about 16.67 units a year, as a planning average only, not a sales target for any single year.

Who this term suits for a shop owner: a shop owner weighing a premises mortgage-scale commitment, where rent or mortgage payments, maintenance and rates all belong in the fixed costs and the units figure alone is not a premises plan.

FAQs

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

Is this shop 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 30 years a shop premises plan?
It can frame one, such as buying rather than renting premises, but the units figure alone is not a premises plan. Rent or mortgage payments, maintenance and rates all belong in the fixed costs.

What does break even miss over 30 years?
It misses price changes, new competitors, online shopping shifts, equipment replacement and loan interest. Over 30 years those matter far more than the original 500-unit figure.

What if fixed costs double to $20,000 over 30 years?
Break even doubles to 1,000 units at today's prices. That is the normal effect of rent and wage growth, and it is why long plans must be updated, not trusted once.
