The short version

  • Each has a real cost: Affirm longer instalment plans carry real interest, up to roughly 36 percent APR depending on the retailer, item and applicant, which is a genuine borrowing cost that the buy now pay later framing can obscure for shoppers who do not read the terms shown before accepting.; 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.
  • They diverge on capability: Affirm covers Pay in 4, Afterpay covers Four-instalment split.
  • 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.

Affirm

  • Longer instalment plans carry real interest, up to roughly 36 percent APR depending on the retailer, item and applicant, which is a genuine borrowing cost that the buy now pay later framing can obscure for shoppers who do not read the terms shown before accepting.
  • Even with no late fees, Affirm reports many loans to credit bureaus, so a missed or late payment on a longer plan can affect a credit score in a way the marketing around interest-free short plans does not prepare shoppers for.
  • Approval and APR both vary by individual loan, so the same shopper can be offered interest-free terms on one purchase and a high APR on another, making the cost unpredictable until checkout.
  • Merchants pay a transaction fee to offer Affirm at checkout, a cost typically built into retail pricing, so shoppers who pay by other means still indirectly subsidise the option even if they never use it.
  • The Affirm Card blurs the line between buy now pay later and a general-purpose credit card, and using it for everyday spending on interest-bearing terms can compound borrowing cost in a way a single point-of-sale purchase would not.

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.

Answered from the vendors’ own pages

Affirm: Does Affirm always charge interest?

No, short Pay in 4 plans over six weeks are typically interest-free if paid on time; longer instalment plans of three to 36 months can carry a disclosed APR up to roughly 36 percent.

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.

Affirm: Does Affirm charge late fees?

No, Affirm does not charge late fees for a missed payment, unlike some buy now pay later competitors, but missed payments can still be reported to credit bureaus.

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.

Affirm: Will using Affirm affect my credit score?

The initial application uses a soft credit check that does not affect your score, but Affirm reports many resulting loans to credit bureaus, so payment history on the loan itself can affect your score.

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.
