Price Per Meter Calculator
Two rolls of cable, two price tags, two different lengths. The only honest comparison is price per meter. Enter the total price and the total length, and this calculator divides one by the other to four decimals, with an optional field for delivery and tax plus a side-by-side comparison for two items.
The answer is always per meter: lengths entered in feet or yards are converted first (1 ft = 0.3048 m, 1 yd = 0.9144 m). Estimate only, not financial advice.
Enter both options below. The comparison uses the same length unit and the same extra costs you set above.
Quick Answer
A $45.00 roll holding 12 meters costs $3.7500 per meter: 45 ÷ 12. Add $8.50 delivery and the true cost becomes $4.4583 per meter. Put a second roll next to it ($79 for 25 meters = $3.1600) and the comparison names the $79 roll cheaper by $0.5900 per meter. Lengths entered in feet or yards are converted first, so the answer is always per meter.
Key takeaways
- Price per meter is total price divided by total length in meters, shown to four decimals so small differences stay visible.
- The length-unit selector converts feet (× 0.3048) and yards (× 0.9144) into meters before dividing. The answer is always price per meter, never price per foot or per yard.
- Extra costs such as delivery, tax and fees are added to the price before dividing, and the same extras apply to both items in a comparison.
- A lower $/m is not automatically the better buy. Offcut waste, quality differences and bulk quantity tiers can overturn the arithmetic, as the section below explains.

How to use the price per meter calculator
Type the total price, the total length and any extra costs, then click Calculate price per meter. The result appears to four decimals, and the two-item comparison underneath needs no second run.
- Enter the total price: the full amount you pay for the roll, pack or length, in your own currency. A comma is fine: 1,200 for 100 meters gives 12.0000. The $45.00 example is pre-filled.
- Enter the total length: how much material you actually get, in the unit you select next. The worked example uses 12.
- Pick the length unit: meters, feet or yards. Feet and yards are converted to meters (1 ft = 0.3048 m, 1 yd = 0.9144 m) before the division, so the headline number is always price per meter.
- Add extra costs if they apply: delivery, tax or fees. They join the price before dividing, which is the only way to get the true cost per meter. Leave the field blank to skip it.
- Compare two items: fill in item A and item B and click Compare items. You get a table of both per-meter prices and a verdict naming the cheaper one with the exact difference, using the same unit and extras as above.
The results stay hidden until you calculate, and Reset restores the worked example. If the inputs are empty, zero or negative, the calculator says exactly which field is wrong instead of guessing.
The formula: total price divided by total length in meters
Price per meter = (total price + extra costs) ÷ total length in meters. That is the entire method, and it is the same normalization behind the unit-price labels on store shelves: unit pricing exists so shoppers can compare products by weight or volume instead of by package, and retail guidance lists price per meter among the standard units for the job.
meters-per-unit: meters = 1, feet = 0.3048, yards = 0.9144
The conversion factors are exact, not rounded. The US National Institute of Standards and Technology records that the foot was redefined in 1959 as exactly 0.3048 meter, and since a yard is three feet, 0.9144 meter follows by multiplication. The meter itself is the SI base unit of length, defined in the SI Brochure maintained by the Bureau International des Poids et Mesures. If you price goods by the piece rather than by length, the cost per item calculator does the same job per piece.
Worked example: the $45 roll, checked three ways
The calculator is pre-filled with a $45.00 roll holding 12 meters. Running it gives $3.7500 per meter, and the same inputs checked three ways all land where they should.
| Check | Inputs | Tool output |
|---|---|---|
| Plain | $45.00, 12 m | 3.7500 |
| With delivery | $45.00 + $8.50, 12 m | 4.4583 |
| Length in feet | $45.00, 12 ft (= 3.6576 m) | 12.3031 |
Hand-check the middle row: 45 + 8.50 = 53.50, and 53.50 ÷ 12 = 4.45833, which rounds to 4.4583. The feet row shows the conversion at work: 12 × 0.3048 = 3.6576 meters, and 45 ÷ 3.6576 = 12.3031 per meter. Every row is a real run of this calculator, so you can reproduce each figure exactly.
Feet and yards: what the length-unit selector actually does
It converts your length to meters before dividing. A length entered in feet is multiplied by 0.3048, in yards by 0.9144, and the answer stays price per meter in every case.
| You enter | Converted to meters (exact) | Example |
|---|---|---|
| 1 foot | 0.3048 m | 10 ft = 3.0480 m |
| 1 yard | 0.9144 m | 10 yd = 9.1440 m |
| 3 feet | 0.9144 m | 3 ft = 1 yd, exactly |
This is a deliberate design choice, and it is worth stating plainly because an earlier version of this page labelled the converted answer “price per foot”, which was wrong: the value was per meter while the label said per foot. The selector now only describes your input; the headline, the comparison table and the copy text all say per meter. If your supplier quotes in yards and you want the answer in yards too, the price per yard calculator gives it in that unit, and for long runs such as fencing the price per kilometer calculator keeps the numbers readable. A shortcut if you need per-foot from a per-meter answer: multiply by 0.3048 ($3.75/m × 0.3048 = $1.1430/ft).
Three things $/m leaves out
The division is honest, but it is not the whole purchase decision. Three factors sit outside the arithmetic:
Offcut waste
If your project needs eleven one-meter cuts, a 12-meter roll at $3.75/m wastes nearly a meter, while two 6-meter rolls might waste nothing. The cheapest $/m loses when the offcuts go in the bin.
Quality
The division cannot see breaking strength, weave density or coating life. A cheaper-per-meter rope with half the load rating is not the better buy for anything load-bearing.
Bulk tiers
The $/m you compute today may drop 20 to 40 percent at the next quantity break. For large jobs, ask the supplier for tiered quotes before deciding; unit-price guidance from extension economists makes the same point about package sizes in general.
If you are setting shelf prices rather than comparing them, the markup percent calculator works the other direction, from cost to price.
What competing calculators miss
Price-per-meter tools fall into three camps, and each leaves something out:
- Single-input tools (Brave Calculator’s price-per-meter page): correct formula and a generous FAQ, but meter-only input. Their own FAQ tells foot users to convert first or find a different calculator, and there is no comparison mode and no extras field.
- Thin formula pages (Calculator Ultra and similar): the formula PPm = TP/L with one worked example. Correct, but nothing to compare with and no guidance on units, extras or edge cases.
- Property tools (price-per-square-meter pages): a different intent entirely. They price floor area for real estate; this page prices linear materials like cable, fabric, rope and pipe. Comparing $/m with $/m² is a category error.
- The gap this page fills: feet and yard inputs converted exactly with the answer honestly labelled per meter, a two-item comparison that names the winner with the exact difference, extra costs folded into the unit price, and four decimals so close calls stay decidable.
Frequently asked questions
Divide the total price by the total length in meters. A $45.00 roll holding 12 meters gives 45 divided by 12 = $3.7500 per meter. If there are delivery charges, tax or fees, add them to the price first: ($45.00 + $8.50) divided by 12 = $4.4583 per meter.
The selector describes your input, not the answer. It tells the calculator that your length number is in feet or yards, so the tool can convert it to meters (1 ft = 0.3048 m, 1 yd = 0.9144 m) before dividing. The result is always price per meter, which is what this calculator is for.
Divide the price by the length in feet directly, or convert from the per-meter answer: multiply $/m by 0.3048. At $3.7500 per meter that is $1.1430 per foot. The dedicated price per yard calculator on this site gives answers in yards if that is the unit your supplier quotes.
Because unit prices are small and differences compound. $3.7500 versus $3.7450 per meter is only half a cent, but it is $5 on a kilometer of cable. Four decimals keep close comparisons decidable instead of rounding them into ties.
Yes, if you want the true cost per meter. Enter them in the extra-costs field and they are added to the total before dividing. In the two-item comparison the same extras apply to both items, so shared delivery or tax cannot tilt the verdict.
Yes, and you do not need to convert by hand. Enter each item’s length in its own unit using the selector, one at a time, and each is converted to meters before the per-meter price is computed. Never divide a yard-priced item by its yard count and compare that figure to a per-meter figure.
No. Factor in waste from cutting (offcuts from a long roll can erase the saving), quality differences such as strength or durability, and whether a bulk quantity tier would lower the unit price further. University extension guidance on unit pricing makes the same caution about package sizes: the bigger pack is usually but not always cheaper per unit.
The calculator strips commas before dividing, so 1,200 for 100 meters correctly gives 12.0000 per meter. Blank, zero, negative or non-numeric entries stop with a message naming the faulty field instead of producing a wrong number.
