The short version

  • Only Afterpay has a free tier, so it costs nothing to try first.
  • Each has a real cost: Afterpay a missed instalment triggers a late fee, and while total late fees on a purchase are capped, repeated missed payments across multiple purchases can add up to a meaningful cost that the interest-free marketing does not foreground.; Increase the published per transaction rates exclude a monthly platform fee that Increase states varies by use case, so the transparent price page cannot produce a total cost and the material part of the deal is still negotiated privately.
  • They diverge on capability: Afterpay covers Four-instalment split, Increase covers ACH origination and receipt.
  • Prices and features above were last checked on 1 September 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Afterpay

  • A missed instalment triggers a late fee, and while total late fees on a purchase are capped, repeated missed payments across multiple purchases can add up to a meaningful cost that the interest-free marketing does not foreground.
  • Afterpay has updated its reporting policies so that late payment history can be shared with credit bureaus in some markets including the US, meaning a product marketed as simple instalments can now affect a credit score.
  • Merchants pay a transaction fee commonly in the 4 to 6 percent range plus a fixed fee, well above standard card processing, a cost that is typically absorbed into retail pricing rather than disclosed to the shopper choosing to use Afterpay.
  • Spending limits and approval are based on repayment history within the app rather than a full credit check, which can make it easier to accumulate multiple concurrent instalment obligations across different purchases than a shopper realises.
  • It is only usable at participating retailers or via the Afterpay Card, so coverage is narrower than a general-purpose credit or debit card despite behaving like one at checkout.

Increase

  • The published per transaction rates exclude a monthly platform fee that Increase states varies by use case, so the transparent price page cannot produce a total cost and the material part of the deal is still negotiated privately.
  • Free allowances are deliberately small at ten account numbers and five physical cards, so any programme issuing accounts or cards at volume moves to quoted pricing almost immediately.
  • Banking is provided through partner banks, so programme approval, compliance obligations and the ability to launch at all depend on a bank relationship you do not control, and post-Synapse bank risk appetite has tightened considerably.
  • The API deliberately exposes payment rail mechanics rather than smoothing them, which is correct engineering but means a team without payments expertise will build reconciliation and return handling wrongly and only discover it when funds go astray.
  • Coverage is United States only, so a company with international payout needs runs a second provider and reconciles two ledgers, and the single API argument disappears at the first cross border customer.

Answered from the vendors’ own pages

Afterpay: Does Afterpay charge interest?

Not on the standard four-instalment Pay in 4 plan if every payment is made on time; longer instalment plans in some markets can carry interest, and missed payments incur late fees regardless.

Increase: Does Increase publish its pricing?

Partly. Per transaction fees for ACH, wires, RTP, FedNow and cards are listed publicly. The monthly platform fee is not, and it is described only as varying by use case.

Afterpay: Can Afterpay affect my credit score?

Afterpay has updated its policies so that late payment history can be reported to credit bureaus in some markets including the US, which can affect a credit score even though the core product is marketed as interest-free.

Increase: Who holds the deposits?

Partner banks, not Increase itself. That relationship determines your programme approval, your compliance obligations and your risk if the bank changes appetite.

Afterpay: Who actually pays for Afterpay to be free for shoppers?

Merchants pay a per-transaction fee, commonly 4 to 6 percent plus a fixed fee, which is generally built into retail pricing rather than shown to the shopper.

Increase: Is it international?

No. Increase covers United States rails only, so cross border payouts require a second provider.

Increase: How is it different from a middleware BaaS platform?

It exposes the rails rather than abstracting them, showing real return codes and settlement timing. That suits teams who understand payments and punishes teams who do not.
