Break-Even Calculator for Makers – How Many Units to Sell

How many units do you need to sell before a project stops costing you money? Enter three numbers and get your break-even point.

Costs you pay regardless of sales: equipment, molds, booth fees, subscriptions.

Materials, packaging, marketplace fees — costs that scale with each sale.

How to use this calculator

Split your costs into two buckets. Fixed costs happen whether you sell one unit or a thousand: the 3D printer or kiln you bought for this product line, molds and jigs, a market booth fee, software subscriptions, a batch of product photography. Variable costs repeat with every unit: materials, packaging, shipping supplies and marketplace fees.

Each sale contributes the difference between its price and its variable cost — the contribution margin — toward paying off the fixed pile. Break-even is simply fixed costs divided by that margin, rounded up to whole units. Sell a $30 item with $12 of variable cost and each sale contributes $18; $500 of fixed costs therefore takes 28 sales to recover.

The number is most useful before you commit. Considering a $600 resin printer for a new product line? If the math says 90 sales to break even and your shop moves 10 units a month, you now know it’s a nine-month bet — decide with open eyes. If the break-even count looks hopeless, either the price is too low (test it with the handmade pricing calculator), the variable cost is too high, or the fixed investment doesn’t fit your sales volume yet. For event-specific versions of this math, the craft fair ROI calculator adds your time into the picture.

Frequently asked questions

What counts as a fixed vs. variable cost?

Fixed: anything you pay once or per period regardless of volume — equipment, molds, booth fees, subscriptions, photography. Variable: anything that scales per unit — materials, packaging, transaction fees, per-order shipping supplies.

Why is the break-even rounded up?

You cannot sell 27.8 units. The calculator rounds up to the next whole unit, so the break-even revenue shown is the revenue at that whole-unit count — you finish that sale slightly ahead, not exactly at zero.

What if my price is lower than my variable cost?

Then no sales volume can ever recover your fixed costs — every sale digs the hole deeper. The calculator flags this instead of returning a number. Raise the price or cut the per-unit cost first.

Should my own labor be in fixed or variable costs?

For make-to-order goods, labor behaves like a variable cost — add your hourly rate × time per unit to the variable cost. For time spent regardless of sales (setup, design), treat it as fixed if you want your time repaid.
