Personal Break Even Units Calculator (15 Years)

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

The Break even units figure is the number of units you must sell to exactly cover your costs: at that number, total revenue equals total costs, so you make neither a profit nor a loss. Selling fewer units leaves you short of covering costs, while every unit sold beyond that number adds to 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 15 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 15 years means 33.33 a year, which is 2.78 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 person: A 15-year term suits a person saving toward a family goal through a steady hobby, for example someone making seasonal crafts for fairs, selling preserves, or running a small photography print shop to build a children's education fund. The pace is 33.33 units a year, so the work can fit around family life, but the product must still be wanted in 15 years, which is a real risk to check.

FAQs

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

Is this personal 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 15 years too long to rely on one product and one price?
It can be. The calculator holds price at $50 and variable cost at $30 for the whole term, but over 15 years both will usually move. If variable cost rises to $35, the contribution falls to $15 and break even rises to 667 units. Review the price and costs every year or two, and treat the 500-unit figure as a starting point, not a 15-year promise.

How does a 15-year term change the sales pace?
It lowers the yearly pace to 33.33 units, which is 2.78 a month, so a seasonal seller can sell most units at fairs and in busy months and still reach the target. The danger is the opposite: a very low pace can hide weak demand, so set a yearly check, such as at least 33 units sold by the end of each year, and act early if sales fall behind.

Can I use a 15-year break-even figure for a seasonal product?
Yes, as a planning figure, but count seasons, not months. Fifteen years may mean only 15 selling seasons for a Christmas craft or a summer garden product, so the target is still 500 units in total, not 500 units every year. Plan stock, storage, and fixed costs around the selling season, and re-check the price before each season.
