Stripe vs Creem vs Polar.sh vs Paddle vs Lemon Squeezy in 2026: The Real Effective Fee Math on $5,800/mo SaaS Revenue

#webdev #saas #startup

Most SaaS founders choose their payment infrastructure based on a single headline number: Stripe's 2.9% + $0.30 processing fee versus a Merchant of Record (MoR) quoting 4% to 5%.

On paper, Stripe looks 1.5% to 2.0% cheaper. In production—once you sell recurring subscriptions globally across North America, the EU, the UK, and APAC—that headline rate is an illusion.

Let's run the exact fee math on a concrete, realistic SaaS workload in 2026:

  • Gross Monthly Volume (GMV): $5,800.00/mo
  • Order Volume: 200 monthly subscription renewals at $29.00/mo
  • Geographic Split: 40% domestic (US) cards, 60% international cards (requiring currency conversion / cross-border settlement)

1. Why Stripe's "2.9% + $0.30" Is Actually 6.63% ($384.80/mo) on Global SaaS

When you run a recurring SaaS on Stripe and need automated invoicing, dunning, and tax calculation, four additional fee layers stack on top of the base card rate:

  1. Base Processing (2.9% + $0.30): $168.20 + $60.00 fixed = $228.20/mo
  2. Stripe Billing (+0.7% of recurring volume): $40.60/mo
  3. Stripe Tax (+0.5% on auto-calculated transactions): $29.00/mo
  4. International Card Surcharge (+1.5% on 60% of GMV = $3,480): $52.20/mo
  5. FX / Currency Conversion (+1.0% on 60% of GMV = $3,480): $34.80/mo

Total Stripe Full-Stack Fee: $384.80/mo (6.63% effective fee), leaving $5,415.20/mo net.
More importantly: because Stripe is a payment processor rather than a Merchant of Record, you remain legally responsible for VAT, GST, and US state sales tax registration, filing, and remittance once you cross local thresholds (which is zero dollars for foreign digital sellers into the EU and UK).

2. Why Lemon Squeezy Reaches 8.62% ($500.20/mo)

Lemon Squeezy (acquired by Stripe) acts as a full Merchant of Record and handles global tax remittance, but stacks multiple surcharges behind its 5.0% + $0.50 headline rate:

  1. Base MoR Fee (5.0% + $0.50): $290.00 + $100.00 fixed = $390.00/mo
  2. International Card Surcharge (+1.5% on $3,480): $52.20/mo
  3. Subscription Renewal Surcharge (+0.5% on $5,800): $29.00/mo
  4. Cross-Border / Payout Spread (~0.5% effective): $29.00/mo

Total Lemon Squeezy Fee: $500.20/mo (8.62% effective fee), leaving $5,299.80/mo net—costing you nearly $200/mo ($2,328/year) more than newer MoR alternatives.

3. The 2026 Merchant of Record Comparison on $5,800/mo GMV

Here is how the four leading Merchant of Record platforms compare on the exact same 200 orders x $29/mo (60% international) workload in 2026:

#1. Creem.io — 5.28% Effective ($306.20/mo Fees -> $5,493.80/mo Net)

  • Pricing Structure: 3.9% + $0.40 per transaction, with 0% international card surcharge and 0% subscription surcharge.
  • The Math: ($5,800 x 3.9% = $226.20) + (200 x $0.40 = $80.00) = $306.20/mo.
  • Takeaway: Creem is currently the lowest-cost Merchant of Record for global SaaS, beating even raw Stripe Full Stack by $78.60/mo while offloading all EU/UK VAT liability.

#2. Polar.sh Pro Tier — 6.42% Effective ($372.60/mo Fees -> $5,427.40/mo Net)

  • Pricing Structure: Polar offers a free Starter tier (4.0% + $0.40 + 1.5% intl + 0.5% sub) and a $20/mo Pro tier that drops transaction fees to 3.8% + $0.40 and eliminates the 0.5% subscription surcharge.
  • The Math: $20.00 monthly fee + $220.40 (3.8%) + $80.00 fixed + $52.20 (1.5% on $3,480 intl) = $372.60/mo.
  • Break-Even Point: Upgrading from Polar Starter to Polar Pro ($20/mo) saves 0.7% on recurring volume (0.2% base + 0.5% subscription fee), meaning Polar Pro breaks even at $1,667/mo GMV.

#3. Paddle — 6.72% Effective ($390.00/mo Fees -> $5,410.00/mo Net)

  • Pricing Structure: Flat 5.0% + $0.50 per transaction with 0% international card surcharge and 0% subscription fee.
  • The Math: $290.00 (5.0%) + $100.00 (200 x $0.50) = $390.00/mo.
  • Takeaway: Because Paddle does not penalize international cards or recurring renewals, its flat 5% + $0.50 beats any 4% MoR that tacks on 1.5% intl + 0.5% sub once your international buyer share exceeds 50%.

#4. Dodo Payments (and Polar Starter) — 6.78% Effective ($393.20/mo Fees -> $5,406.80/mo Net)

  • Pricing Structure: 4.0% + $0.40 base + 1.5% international + 0.5% subscription.
  • The Math: $232.00 base + $80.00 fixed + $52.20 intl + $29.00 sub = $393.20/mo.
