Gumroad vs Polar fees in 2026: the actual maths for developers
If you last compared Gumroad and Polar in 2024, both halves of your comparison are out of date. Gumroad became a merchant of record in January 2025, which killed the strongest argument for switching. Polar repriced in May 2026, which weakened the second-strongest. Here is where the maths actually stands in mid-2026 — with the caveat, disclosed up front, that we sell our own template through Polar, so we have skin in this comparison.
The headline rates
| Per sale | Notes | |
|---|---|---|
| Gumroad — direct sales | 10% + $0.50 | Sales through your links/profile |
| Gumroad — Discover | 30% | New customers via Gumroad's marketplace |
| Polar — free (Starter) | 5% + 50¢ | Orgs created after 27 May 2026 |
| Polar — paid plans | 3.8% + 40¢ down to 3.4% + 30¢ | Pro → Scale tiers |
Both platforms are merchants of record: they are the legal seller, they charge the buyer, and they owe the VAT/GST/sales tax in the buyer's country, not you. For a UK sole trader selling downloads worldwide, that is the feature that makes either of them worth 5–10% — the alternative is registering for VAT schemes in jurisdictions you couldn't place on a map.
Two Polar line items that don't make it into headline comparisons:
- International cards cost +1.5%. If you're a UK developer, most of your buyers pay with non-US cards — mentally price Polar's free plan at ~6.5% + 50¢, not 5% + 50¢.
- Payouts aren't free. Polar (via Stripe) charges $2 per month in which you receive a payout, plus 0.25% + $0.25 per payout. Trivial at volume; at £50/month of sales it's another ~4% gone. Gumroad's payout costs vary by country and method, and were free for most direct-deposit cases at the time of writing.
Worked examples (direct sales, international card on Polar)
| Sale price | Gumroad net | Polar free-plan net | Effective fee gap |
|---|---|---|---|
| $5 | $4.00 (20.0%) | $4.18 (16.5%) | 3.5 pts |
| $19 | $16.60 (12.6%) | $17.27 (9.1%) | 3.5 pts |
| $49 | $43.60 (11.0%) | $45.32 (7.5%) | 3.5 pts |
Polar wins by ~3.5 points of margin across the range (5 points if your buyer happens to use a US card), before payout fees. It's real money but it isn't the 2024-era "half the fees" story — Gumroad's $0.50 fixed fee and Polar's 50¢ cancel out, and the percentage gap is 10% vs ~6.5% for a typical UK seller.
The number that actually dominates this table is the one in the first section: 30% on Gumroad Discover sales. If Gumroad's marketplace sends you meaningful traffic, that 30% might still be the best marketing spend available to a solo developer, because the alternative is doing your own distribution. If it sends you nothing — which is the common case for niche developer tools — you're paying 10% for what Polar does for ~6.5%.
What the fees don't capture
Gumroad is a storefront; Polar is an API. A Gumroad product page exists the moment you upload a file. Polar gives you a hosted checkout and a minimal hosted storefront, but it assumes the real store is yours: your domain, your pages, your SEO. That's either the point or a day of extra work, depending on who you are. (If it's the day of work, that's the gap our template closes — one typed catalog file, no database, checkout wired.)
Polar's API surface is the actual product. Products, checkouts, orders, discounts, licence keys, usage-based billing, webhooks — all first-class REST endpoints with typed SDKs. We publish products and reconcile orders from scripts. Gumroad has an API, but it is visibly not where the company's attention goes.
Audience portability is equal now. Both platforms let you export customer emails; neither locks your catalog. The switching cost is the storefront work, not the data.
The honest recommendation
- You already sell on Gumroad and Discover brings you sales: stay. 30% of a sale you'd never have made is free money, and migrating to save 3.5 points on direct sales rarely pays for the disruption.
- You're a developer starting from zero with your own site or the willingness to build one: Polar's free plan is the better default in 2026 — lower fees on every direct sale, and the API means your store can grow into licence keys and subscriptions without replatforming.
- You sell a handful of low-priced items with no site: it's closer than fee tables suggest. Gumroad's instant storefront may be worth more than the margin difference until you're doing real volume.

Fees verified 3 July 2026 against both platforms' published pricing. Polar repriced on 27 May 2026 (organisations created before that date keep 4% + 40¢ indefinitely); Gumroad's current structure dates from its January 2025 merchant-of-record change. If you're reading this much later, re-check both.
