For dropshippers & online sellers

Know what
you actually keep.

Type your cost and the price you’d list at. Kârly tells you the net profit on Trendyol, Etsy, Amazon, eBay — same math, every marketplace — so you can decide where to list before you list.

How it works

Three taps to a real number.

Most marketplace calculators ask for fifteen fields and still get the math wrong. Kârly pre-fills your marketplace’s commission and VAT, so you only enter what you actually know.

01

Pick a marketplace

Trendyol, Hepsiburada, Amazon, Etsy, eBay — 10 in total. We've already loaded each one's commission, VAT, and any listing fees.

02

Enter cost & price

What you paid for it. What you're listing it at. That's enough to get a real answer. Shipping and ads are optional — tap to expand.

03

See your net, line by line

Margin, ROI, breakeven price, and a plain-language breakdown of every fee. Share a PDF or save it to History to compare later.

Marketplaces

Ten marketplaces.
One calculator.

Cross-border selling is the wedge. Most calculators handle Etsy or Trendyol, never both. Kârly handles both — and then some.

What we won’t do

Three things we’ll never do to you.

Free tools have a habit of selling you out for ad pennies. Kârly is the opposite — your numbers are yours, your phone stays clean, and we tell you exactly what Pro gives you.

No ads. Ever.

We have never wired AdMob, and we never will. Not in Free. Not in Pro. Not later “to support the team.” The number on your screen is the number you came for.

No tracking.

No analytics SDK. No third-party scripts. Your saved calculations live on your device in your phone's preferences. We don't have a server that stores your data, because we don't have a server.

Honest paywall.

Two paid tiers. Pro removes the daily cap and adds History + Compare. Pro+ adds the full dropshipping math — ad CPA, return rate, source-to-sale margins. We don't promise features we haven't built.

Pricing

Free is free.
Pro is small. Pro+ is for serious dropshippers.

Test product ideas free, forever. Get History and Compare for $3.33 a month with Pro. Add the full dropshipping math — return rate, ad CPA, source-to-sale margins — with Pro+ for $6.66 a month.

Honest answers

Things people actually ask.

Why is the free tier capped at 3 calculations a day?
Because a real calculator with up-to-date marketplace fees costs us something to maintain, and we refuse to run ads. Three a day is enough to test product ideas casually; if you're listing daily and want History to keep your numbers, Pro pays for itself. If you're running paid ads and need return-adjusted margins, Pro+ pays for itself faster.
Are the commission rates accurate?
They are the marketplaces' published default rates. Category-specific tweaks and seller-tier discounts exist — you can override commission and VAT on every calculation, and we'll honor your number.
Does Kârly sync with my Etsy / Amazon / Trendyol account?
No. Kârly is a manual calculator, not an inventory sync tool. You type the numbers, we do the math. That's also why it works without an internet connection and why your data never leaves your phone.
Where does my saved data live?
On your phone, in the OS's encrypted preferences store. There is no Kârly account. There is no Kârly server. If you delete the app, your data is gone — which means uninstall & reinstall is the only way to “reset” everything.
iPhone version?
Coming. Android first — that's where our Turkish seller community actually is. iOS lands after Android revenue covers the Apple Developer Program fee. Honest.
I want a feature you don't have. Can I write to you?
Yes — hi@nexutility.com. Cross-marketplace SKU comparison, live FX, and per-category commission tables are all on the roadmap; we'd rather build them based on what you actually need than guess.

Stop guessing.
Start knowing.

Free to download. Free to keep. Three calculations a day is genuinely enough to try every product idea you’ve been sitting on.
