You added YITH WooCommerce Product Add-Ons, built your options, set a price on each one, and it worked. Then a product came along where the price is not “add $5”. It is 2.4 by 1.5 metres of velvet at $8 a square metre, plus a setup fee. Add-on options cannot do that sum, and that is the wall most people hit right before they search for a YITH WooCommerce Product Add-Ons alternative.
I build WooCommerce plugins on my own, and mine is a price calculator, so I will not pretend it is a drop-in copy of YITH. It is the alternative for one specific reason: it works the price out from a formula. Below I’ll be straight about what YITH does better, where the calculator wins, and how to tell which one you actually need. I read YITH’s own pages on 14 July 2026 for this; click through and check, because plugins change.
Quick answer: YITH Product Add-Ons adds options that each add a fixed or percentage cost. It is a strong, mature add-ons plugin, and its free version is generous. PriceWise is a price calculator: it works the total out from a formula (area, per metre, per night, measurements with waste and rounding). Pick YITH for surcharge-style options; pick PriceWise when the price is maths.
What YITH Product Add-Ons does well (credit where it is due)
Let me be fair first, because YITH is a good plugin and for a lot of stores it is the right one. From its own pages:
- You add option blocks (radio buttons, text, dropdowns, checkboxes) and give each choice a fixed or percentage cost, or a discount.
- Conditional logic: show option B only when the customer picks something in option A.
- The premium version adds colour swatches, file upload, date fields, and product upsell options.
- It is mature and widely used: 20,000+ active installs on WordPress.org, where the free version is rated 3.7 out of 5.
Honestly, the free version of YITH Product Add-Ons is capable, and if your customisation is “tick this box, pay $5 more”, you may not need anything else. Their premium is $119.99 a year on their site (checked 14 July 2026).
The one thing an add-ons plugin cannot do
Add-on plugins price options by adding them up. Choice A is +$5, choice B is +10%, and the plugin sums them onto the base price. That covers a huge number of stores. What it cannot do is real maths across the customer’s numbers.
Say the price is width times length times a rate, then rounded up to whole boxes, with a minimum charge. Or metres of cable times a price per metre. Or nights times a nightly rate. There is no “add $5” that produces those. You need a formula. That is the line between an add-ons plugin and a price calculator, and it is the whole reason PriceWise exists.
What PriceWise does instead
PriceWise puts a calculator on the product. You write one formula, and the total updates live as the customer fills in the fields. The formula language has real operators and functions: brackets, plus round, ceil, floor, min, max, abs, and if. So the price can be genuine maths instead of a sum of surcharges.
It is not only formulas, though. PriceWise Pro also has the option fields you would expect from an add-ons plugin, so it overlaps YITH’s ground too: colour swatches, dropdowns, checkboxes, a file upload for artwork, conditional show-and-hide rules, and every choice saved to the order. Here it is on a t-shirt product, where each option carries its own price and the total moves live:
And the part YITH cannot reach, a price calculated from measurements. This flooring product charges by the square metre, adds waste, and rounds up to whole boxes, all live:

PriceWise vs YITH Product Add-Ons, side by side
Facts from each plugin’s own pages, checked 14 July 2026. Prices and ratings change, so verify before you buy.
| PriceWise (mine) | YITH Product Add-Ons | |
|---|---|---|
| What it is | A price calculator (formula + measurement) | A product add-ons / options plugin |
| Free version | Yes, on WordPress.org | Yes, on WordPress.org |
| Paid price (1 site) | $49 a year, or $99 once | $119.99 a year |
| Priced options (swatches, upload, conditional) | Yes (Pro) | Yes |
| Formula pricing (area, per unit, min/round) | Yes, this is the point | No |
| Measurement fields (units, waste, box rounding) | Yes (Pro) | No |
| Upsell / related-product options | No | Yes |
| Free-version rating (WordPress.org) | 5 stars (small sample, new) | 3.7 stars (57 reviews) |
I have put my weak spots in there on purpose. YITH is more established, and it has upsell options that I do not. If those matter to you, that is a real reason to stay with YITH.
Which one should you pick
- Options that add a set cost (gift wrap +$5, engraving yes/no, a topping list), with conditional logic and upsells: stay with YITH. Its free version may be all you need.
- A price worked out by maths (by area, by the metre, by weight, by the night, measurements with waste and rounding): that is PriceWise, because a formula is the only thing that gets those right.
- Both, in one plugin (priced options AND a calculated total): PriceWise Pro does both, which is often why people switch.
Can you try it free?
Yes. The free version of PriceWise is the formula calculator with number fields, so you can test the exact thing YITH cannot do, calculated pricing, without paying. The option fields (swatches, file upload, conditional rules) and the measurement fields are the Pro part, at $49 a year or $99 once. I broke down what the free version covers in a separate guide.
FAQ
Is PriceWise a drop-in replacement for YITH Product Add-Ons? Not exactly, and I would not claim it. For calculated pricing it does more. For pure add-on surcharges with upsells, YITH’s free version is a fine choice on its own. Pick by the job.
Does PriceWise have conditional show-and-hide, like YITH? Yes, in Pro. You can show a field only when another field has a certain value.
Can it take a file upload for artwork, like YITH premium? Yes, in Pro. The file lands on the order with the customer’s other choices.
What can YITH do that PriceWise cannot? Upsell “related product” options, and it has a bigger install base and longer track record. If those are deciding factors, stay with YITH.
Can I move my options across without redoing everything? There is no automatic importer between the two, no. You rebuild the fields in PriceWise, which for most products is a few minutes.
The honest bottom line
If YITH Product Add-Ons is doing what you need, there is no reason to switch, and I am not going to invent one. But if you keep running into prices that an add-on cost cannot express, the missing piece is a formula, and that is exactly what PriceWise Calculator Pro is for: $49 a year, or $99 once, which is less than one year of YITH premium. Try the live demos or the free version first, and the documentation has the details.
