How to price products sold by measurement
Selling by the square foot, yard, kilogram, or cubic meter makes pricing trickier than a flat per-item SKU — a small error in your per-unit price multiplies across every order. The reliable method is margin-based pricing: take your real cost per unit and divide by one minus your target margin. That locks in the margin you want instead of hoping a guessed markup is enough.
Price per unit = cost per unit ÷ (1 − target margin)
Why you must add for waste and offcuts
Anything cut to size loses material. Flooring has trim waste, fabric has pattern matching, tile breaks, cable has end scrap. If a job needs 100 units but you buy and scrap 108, your true cost per sold unit is 8% higher than the sticker cost. That gap is invisible until you reconcile a job and wonder where the profit went. This calculator adds your waste percentage to cost before it sets a price, so the margin survives contact with real offcuts.
Margin-based pricing vs guessing a price per unit
Many merchants price by eyeballing a round number or copying a competitor — then discover the margin is far thinner than they assumed. Margin and markup are also routinely confused: a 50% margin is a 100% markup. Pricing from margin removes the guesswork and the calculator shows the equivalent markup alongside it, so you always know exactly what you keep on every unit sold.
Pricing boxes and packs by coverage
If you sell in boxes — a carton of tile that covers 35 sq ft, a roll of wallpaper, a pallet of mulch — price the unit first, then multiply by the coverage. A $2.09 / sq ft price on a box covering 35 sq ft becomes a $73.15 box price. Enter coverage-per-box in the advanced options and the tool computes both the per-unit and per-box price so your storefront and your shelf tags agree.
Frequently asked questions
- How do I price a product sold by measurement?
- Start from your real cost per unit, then divide by one minus your target margin. For example, if a square foot of flooring costs you $1.04 after waste and you want a 50% margin, charge $1.04 ÷ (1 − 0.50) = $2.08 per square foot. Pricing from margin (not a guessed markup) guarantees the margin you actually want.
- Why do I need to add for waste and offcuts?
- Products cut to size always lose material — flooring has trim cuts, fabric has pattern matching, tile breaks. If a job needs 100 sq ft but you buy and scrap 108, your true cost per sold square foot is 8% higher. Ignoring waste silently eats your margin, so this calculator bakes a waste percentage into the cost before pricing.
- What's the difference between margin and markup?
- Margin is profit as a percentage of the selling price; markup is profit as a percentage of cost. A 50% margin is a 100% markup. They're easy to confuse, and confusing them is how merchants underprice. This tool prices from margin and also shows the equivalent markup so the numbers are unambiguous.
- How do I price products sold in boxes or packs?
- Price per unit first, then multiply by the coverage of a box. If your recommended price is $2.09 per sq ft and a box covers 35 sq ft, the box sells for $2.09 × 35 = $73.15. Enter your coverage-per-box in the advanced section and the calculator does this for you.
- Can I check whether my current price is profitable?
- Yes. Enter the price you currently charge per unit in the advanced section. The calculator runs reverse mode and shows your true margin after waste — flagging it green if healthy, amber if thin, or red if you're selling below cost.
- Is this calculator free?
- Yes — free forever, no signup, no email. Every calculation runs entirely in your browser, so your numbers never leave your device.
