This is a comparison of Custom Price Calculator and the Shopify apps worth considering instead for made-to-measure pricing.
For a supplier grid, size-based quantity breaks and a second language, Appify Custom Product Options is the alternative to start with. It reads your grid at any size, prices every choice in one calculation, and carries the order through the cart, the reorder and the translation. Every feature is on every plan.
Below: what Custom Price Calculator does well, what to check in any alternative, and a side-by-side table.
What Custom Price Calculator does well
Custom Price Calculator does the job it was built for. It's a measurement calculator with a drag-and-drop builder, templates and AI setup from a description, plus a setup call where its team builds your first calculator. Shoppers enter size, area, length, weight or quantity.
Made-to-measure pricing often needs more: a supplier grid, a minimum, and a discount that depends on the size of the order. The checklist below covers what to look for.
What made-to-measure pricing needs
Check any app against the price sheet you use today. These are the parts that matter once a product is cut to size.
- A grid read at any size. A shopper types 70 where your sheet has 60 and 72. The app should apply the rule your sheet follows.
- Formulas that read every choice. The material sets the rate, the size sets the area, and the price is the two together.
- Quantity breaks that follow the size. Ten large pieces and ten small ones don't earn the same discount.
- A minimum and your fees, charged the way you quote them.
- Limits that move with the choice. The maximum width changes with the material.
- A wrong price you can trace, before a customer finds it.
- An order that keeps its details. Translations, cart edits and reorders all need the options intact.
1. Appify Custom Product Options
It prices the whole configuration: the size, the material, the extras and the quantity, in one calculation.
Your supplier grid, at any size
Pricing tables hold your rate sheet in a spreadsheet-style grid: width by drop, or size by material. When a size falls between the lines, you choose the rule. Match exactly, take the nearest lower or nearest upper line, take the nearest, or blend between the lines.
Say your grid has 60, 72 and 84 inch widths and a shopper types 70. Nearest upper reads the 72 column. Interpolate blends the 60 and 72 columns. Your sheet decides which is right, and the setting matches it.
One table can serve every calculator in your store, so a rate change is made once.
Formulas for everything else
Formulas run on any option and on the total price. They use if/then logic, table lookups, and math and rounding functions. A pricing variable such as AREA is written once and reused in every formula and rule.
Quantity breaks that follow the size. A simple ladder by quantity, or a two-way grid where the discount depends on quantity and on width or area. Each break can be a percentage off, an amount off, or a set price per unit.
- Fees. A setup fee on every order, or a rush fee only when Rush is picked. Fixed fees are never discounted.
- Minimum and maximum price on the total, so no job goes out under your floor.
- Price adjustments. Add a percentage when the material is premium, or a flat charge when the area passes a size you set.
- Limits that move. One choice can set another option's value, its range or its step.
The order keeps its details
- Translations. Up to 10 languages, and the option names and choices reach the cart line and the order in the shopper's language.
- Currency. Calculated prices convert through Shopify Markets.
- Edit options. Shoppers change their choices from the cart.
- Reorder and recovery. Appify Reorder brings a past order back with its options, which Shopify's Buy again doesn't. Restore your cart rebuilds an abandoned cart whole.
You don't build it by hand
Describe your pricing to Chat with AI, or attach the spreadsheet you already use. It builds the options, the grid, the formulas, the discounts, the rules and the styling. You can edit anything it writes.
When a price comes out wrong, the Troubleshoot tab shows every part of the formula with the preview's choices loaded and points to the fix. Or tell Chat with AI the number you expected, and it opens that tab for you.
Who it's for: any store whose price comes from a size, a sheet or a rule. For the fabric, rug and curtain case, see how to sell fabric, rugs and curtains by size.
2. SE: Option Price Calculator
You'll meet other names while searching, so here is how they line up. SE: Option Price Calculator is the next most capable formula engine after Appify Custom Product Options. It puts formulas on every option and on the final price, reads pricing tables and lookups, and uses product metafields in formulas.
It also calculates weight by formula, shows and hides options by rule, and offers quantity breaks. Shopify Markets currency and option translation are built in. It's a focused calculator for measurement-based products, and a strong one.
Appify Custom Product Options adds the wider engine around the formula: two-way discounts, fees, minimums, price adjustments, troubleshooting and AI setup.
3. Custom Price Calculator
Where it fits: a measurement calculator you can stand up quickly, with a person to help. Shoppers enter their size and see the price update. It handles tiered rates and size-band price grids from your spreadsheet.
Where it stops: the sizes between the bands. How it prices a size that falls between two bands isn't stated, and a made-to-measure shopper will type one. In Appify Custom Product Options you pick the rule for sizes between the lines, so the price follows your sheet.
4. Options Price Calculator
Where it fits: formula-based dynamic pricing. It covers dimensions, conditional logic, a live preview and AI-powered generation.
Where it stops: after the add-to-cart. Its listing doesn't mention editing options from the cart or reordering with the same choices. In Appify Custom Product Options the shopper reopens the calculator from the cart with the choices filled in, and a past order comes back through Appify Reorder.
5. Price Calculator by Measure
Where it fits: products sold by area, length or volume, in imperial or metric, with a margin for error. It suits flooring, tiles, paint, wallpaper and fabric.
Where it stops: the choices beside the measurement. It handles the measurement and the quantity. It doesn't mention formulas, pricing tables or priced options. A made-to-measure product carries a material and extras, and Appify Custom Product Options prices them together with the size.

Compared October 2026. Apps change, so features may have moved since.
Appify Custom Product Options is green on all 12 rows. No other app here is green on more than 2. The grid, the formula, the discount that follows the size, and what happens after checkout, in one app with every feature on every plan.
Moving over without rebuilding
The calculators you already built are the real reason people stay. Here is how the move goes.
- Hand over what you have. Attach your price sheet and a screenshot of a product page as it looks today, and tell Chat with AI what you sell.
- Check it against real orders. The live preview shows the price as you change choices. Enter the sizes from last week's orders and compare.
- Publish when it matches. Nothing reaches the storefront until you publish, so the old calculator keeps selling while you test.

How to decide
If your price comes from a grid, a measurement and a few rules, Appify Custom Product Options is the one to install. It prices the whole rate card, not one line of it, and every feature is already on your plan.
If you're weighing the other apps, SE: Option Price Calculator is the one to look at next. Choosing any of the others is choosing fewer pricing features, not different ones.
