Polar vs Lemon Squeezy 2026: Merchant-of-Record Fees Compared

Polar and Lemon Squeezy are both merchant-of-record platforms aimed at indie and digital-product sellers, and they tie on the free tier at 5% + 50¢. The split is structural: Polar offers rate-reducing paid tiers (down to 3.4% + 30¢ on Scale) while Lemon Squeezy holds one rate plus surcharges. This article prices both on a concrete $29 sale, works the paid-tier crossover, and flags Polar's May 2026 pricing change.

1. The fee tables, side by side

All figures verified against official pricing pages as of May 25, 2026.

Plan / component	Polar	Lemon Squeezy
Entry rate (free tier)	Starter: 5% + 50¢[1]	5% + $0.50[2]
Paid tier 1	Pro $20/mo: 3.8% + 40¢[1]	None
Paid tier 2	Growth $100/mo: 3.6% + 35¢[1]	None
Paid tier 3	Scale $400/mo: 3.4% + 30¢[1]	None
International card surcharge	+1.5%[1]	+1.5%[2]
PayPal surcharge	Not publicly documented (as of May 2026)	+1.5%[2]
Subscription surcharge	+0.5% (Early Member only)[1]	+0.5%[2]
Dispute fee	$15 per dispute[1]	Not publicly documented (as of May 2026)
Open source	Yes[1]	No
Merchant of record	Yes[3]	Yes[2]

The free entry tiers are a dead heat. Polar's advantage is the tier ladder; Lemon Squeezy's is a simpler single rate with no monthly fee to weigh. Polar's open-source codebase matters for sellers who want to self-host or audit the billing layer.

2. The math on a $29 sale

Worked on a $29 charge from a US card, before any subscription or international surcharge. Polar Starter and Lemon Squeezy use the same base, so they tie until you add a paid tier or a surcharge.

Platform / tier	Fee on $29	Effective rate	Net to you
Polar Starter / Lemon Squeezy (5% + 50¢)	$1.95	6.72%	$27.05
Polar Pro (3.8% + 40¢)	$1.50	5.17%	$27.50
Polar Growth (3.6% + 35¢)	$1.39	4.79%	$27.61
Polar Scale (3.4% + 30¢)	$1.29	4.45%	$27.71

The arithmetic on Polar Pro: 0.038 × $29 + $0.40 = $1.10 + $0.40 = $1.50, which is 1.50 / 29 = 5.17%. On the same $29 sale, the per-transaction saving over the 5% + 50¢ base is $0.45 on Pro. Pro's $20/month fee is recovered once you process about 45 transactions a month at this size (45 × $0.45 = $20.25). Above that volume, Pro is strictly cheaper than the free Starter rate.

3. Polar's paid tiers change the picture

Lemon Squeezy has no equivalent rate-reducing plan, so its effective rate is fixed at the base plus any surcharges regardless of volume. Polar's tiers create three crossover points where paying the monthly fee beats the free rate:

• Pro ($20/mo, 3.8% + 40¢): recovers its fee at roughly $1,600 of monthly volume on $29 tickets (about 55 sales). Below that, stay on Starter.
• Growth ($100/mo, 3.6% + 35¢): worth it once monthly volume is large enough that the rate cut from 3.8% to 3.6% plus the smaller fixed fee covers the extra $80/month over Pro, roughly $40,000 of monthly volume.
• Scale ($400/mo, 3.4% + 30¢): for high-volume sellers where the 3.4% rate on six-figure monthly volume justifies the $400 fee.

The practical read for an indie seller: start on Polar Starter (free, 5% + 50¢), move to Pro once monthly fee volume passes about $500, and re-run the crossover before each upgrade. Lemon Squeezy is simpler (no plan to optimize) but leaves the volume discount on the table.

4. Polar's May 2026 pricing change

Polar restructured its pricing around May 27, 2026^[1]. Organizations created before that date were grandfathered on an Early Member rate of 4% + 40¢ plus a 0.5% subscription surcharge, held indefinitely. Organizations created on or after May 27, 2026 start on the Starter plan at 5% + 50¢ with no grandfathered rate, and can opt into the paid tiers for a lower percentage.

The implication for a seller signing up now: you are on the new structure, so the comparison above (Starter 5% + 50¢ with paid-tier ladder) is the one that applies. The old 4% + 40¢ Early Member rate is closed to new accounts. If you held a pre-May-27 Polar account, your grandfathered rate persists, which can be cheaper than the new Starter tier for low-volume subscription sellers.

5. Decision guidance

• Brand-new indie seller, low volume: tie at 5% + 50¢. Pick on developer experience; Polar's open-source codebase appeals if you want to audit or self-host.
• Above ~$500/month in fees: Polar Pro at 3.8% + 40¢ beats Lemon Squeezy's flat 5% + 50¢. The monthly fee is recovered quickly.
• High-volume digital seller: Polar Growth or Scale drives the rate toward 3.4%, which Lemon Squeezy cannot match without a custom deal.
• Heavy PayPal usage: Lemon Squeezy lists a +1.5% PayPal surcharge; Polar does not publicly document one, so verify PayPal handling directly before relying on it.

Frequently asked questions

Is Polar cheaper than Lemon Squeezy in 2026?

On the free tier, they match: Polar's Starter plan is 5% + 50¢ per transaction and Lemon Squeezy is 5% + $0.50, both verified as of May 2026. Polar gets cheaper if you pay for a higher tier. Polar Pro at $20/month drops the rate to 3.8% + 40¢, Growth at $100/month to 3.6% + 35¢, and Scale at $400/month to 3.4% + 30¢. Lemon Squeezy stays at 5% + $0.50 with no rate-reducing paid plan, so Polar wins for sellers with enough volume to cover a tier fee.

Are Polar and Lemon Squeezy both merchant of record?

Yes. Both act as the legal merchant of record, calculate and remit VAT and US sales tax in every jurisdiction, and hold the tax-registration liability. Polar is notable for its open-source codebase, which Lemon Squeezy is not. The merchant-of-record model is the reason both charge roughly 5% rather than a bare processor's 2.9% + 30¢.

Did Polar change its pricing in 2026?

Yes. Organizations created before May 27, 2026 were grandfathered on an Early Member rate of 4% + 40¢ plus a 0.5% subscription surcharge. For organizations created on or after May 27, 2026, the entry rate is the Starter plan at 5% + 50¢, with no grandfathered rate. New sellers signing up now start on Starter and can move to a paid tier for a lower percentage.
