Affirm vs Afterpay
Affirm
B-
Affirm is a buy-now-pay-later provider founded in 2012 by Max Levchin, Nathan Gettings, Jeffrey Kaditz and Alex Rampell, headquartered at 221 Main Street in San Francisco and listed on Nasdaq as AFRM since January 2021. For the fiscal year ended 30 June 2026 it reported $50.2 billion of gross merchandise volume, up 37%, across approximately 571,000 active merchants and 27.8 million active consumers. Merchants integrate Affirm as a checkout option, Affirm underwrites and funds the consumer, and the merchant is paid in full up front minus a fee. Two things make it materially different from card acceptance: Affirm bears the consumer fraud risk on transactions it approves, and the merchant fee is several times a card rate — third-party surveys of mid-market merchants report 2% to 8%, while Affirm's own filings put blended merchant network revenue at 2.3% of GMV in FY2026. Its BBB profile is A+ and accredited; its consumer Trustpilot score is 1.7 across roughly 7,700 reviews.
Afterpay
B
Afterpay is the buy-now-pay-later network founded in Sydney in October 2014 by Nick Molnar and Anthony Eisen, and owned since January 2022 by Block, Inc. — the deal was announced in August 2021 at a headline US$29 billion and completed on far less, reported at roughly US$14 billion in Class A shares, because Block's own share price had fallen in the interim. For a merchant, the proposition is straightforward: offer shoppers four interest-free instalments over six weeks, or a monthly plan over six or twelve months, get paid up front rather than waiting for the customer to finish paying, and let Afterpay carry the fraud and non-payment risk. In exchange the merchant pays a commission Afterpay does not publish — third-party reviewers consistently report a range around 4% to 6% plus roughly $0.30 per transaction, several times the cost of taking the same sale on a card. Afterpay's own merchant marketing claims a 58% increase in average order value among accepting merchants and $8.6 billion of incremental US sales delivered over the preceding twelve months. Under Block, the product has increasingly become a Cash App feature rather than a standalone checkout button: Afterpay Post-Purchase and, from 2026, Afterpay Pre-Purchase let Cash App Card holders convert everyday card spend into instalments at any merchant, whether or not that merchant has ever signed an Afterpay agreement.
VS
Overview
Affirm and Afterpay are both buy-now-pay-later networks that approve the shopper, pay the merchant upfront and carry the consumer credit risk. The structural difference is who pays for the plan. Afterpay is entirely merchant-funded: every plan is interest-free to the shopper, so the commission is the whole of Afterpay's merchant economics. Affirm splits it - Pay in 4 is 0% APR and merchant-funded, but its longer monthly plans run at 0-36% APR, so on interest-bearing volume the consumer carries much of the cost and the merchant discount rate falls. That is why Affirm can underwrite a $3,000 purchase over three years and Afterpay cannot. Neither publishes a merchant rate card. Payment Review grades Afterpay B and Affirm B-.
Key Takeaways
- ✓Affirm settles faster and more predictably: it calculates the previous day's charges daily and its lending partners initiate ACH the same day, arriving in 1-3 business days.
- ✓Afterpay assigns each merchant a settlement period of between 1-5 business days in the merchant agreement, with bank ACH time on top.
- ✓Affirm reaches further up the ticket: 0-36% APR monthly financing funded partly by the shopper, against Afterpay's interest-free Pay in 4 and Pay Monthly.
- ✓Afterpay wins distribution in the US - Block owns it alongside Square and Cash App, so a Square seller can switch it on without an integration project.
- ✓Affirm discloses its numbers quarterly as a listed company; Block no longer breaks Afterpay out, so a merchant cannot see its trajectory.
Affirm
Affirm suits merchants selling considered, higher-ticket purchases that need real financing rather than a four-instalment split, and who want daily settlement and a partner whose results are published every quarter.
Afterpay
Afterpay suits small-ticket discretionary retail - fashion, beauty, accessories - and above all US merchants already inside Block's ecosystem, where it is available natively through Square and reaches Cash App shoppers.
The Verdict
It Depends on Your Needs
Why?
These are not the same instrument, so there is no single winner. The deciding question is what you sell. Afterpay is interest-free to the shopper and therefore entirely merchant-funded, which caps it at the small-ticket discretionary end - fashion, beauty, accessories - where a four-instalment split is the whole proposition. Affirm charges the shopper 0-36% APR on its longer plans, and that is precisely what lets it underwrite a purchase Afterpay structurally cannot. Affirm also settles better: a daily cycle reaching the bank in one to three business days, against a contractual period of one to five business days plus ACH. Set against that, Afterpay is graded higher by Payment Review, scores better on support, and owns the distribution that matters most to a US small business - a Square seller can offer it without an integration project, and Cash App puts it in front of a large shopper base. Sell high-ticket and take Affirm; sell small-ticket, or already run on Square, and take Afterpay. Neither publishes a rate, so get both quotes.

Best For Your Business
Recommendations based on your business type
Furniture, electronics or equipment retailer with a high average order value
Recommended
Affirm
Affirm's monthly plans run at 0-36% APR, so the shopper funds part of a long term and the purchase can be spread far beyond a four-instalment split. Afterpay's plans are interest-free throughout, which is exactly why its range stops short of this ticket size.
Fashion, beauty or accessories brand selling small baskets
Recommended
Afterpay
This is the segment Afterpay was built for and where an interest-free Pay in 4 is the entire proposition. Affirm will quote here too, but its advantage - long-dated interest-bearing financing - does nothing for a $60 basket.
US small business already taking payments with Square
Recommended
Afterpay
Block owns Square, Cash App and Afterpay, so Afterpay is native to that stack and needs no separate integration or contract, and the same decision reaches Cash App's shoppers. Affirm would arrive as an additional third-party method with its own onboarding.
Merchant that needs settlement it can forecast
Recommended
Affirm
Affirm runs a fixed daily clock and its lending partners initiate ACH the same day, reaching the bank in one to three business days. Afterpay assigns a settlement period of between one and five business days in the contract, so two merchants on the same platform can wait very different lengths of time.
Retailer selling into New Zealand
Recommended
Afterpay
Afterpay serves New Zealand and Affirm's business site does not offer it - its regions are the United States, Canada, Australia and the United Kingdom. For that market the comparison does not arise.

Frequently Asked Questions
Common questions about this comparison
Neither publishes a rate, so the only honest answer is that it depends on your quote and your mix. The structural point is more useful than any reported number: Afterpay is interest-free to the shopper, so your commission funds the entire plan. Affirm charges 0-36% APR on its longer plans, so where volume is interest-bearing the shopper carries part of the cost and the merchant rate is lighter - but Affirm's promotional 0% APR programmes, which are the ones that look like Afterpay, are reported to be among the more expensive in the category. Get both quotes against your actual average order value.
Affirm, and more predictably. Affirm totals the previous day's captures less refunds each morning and its lending partners initiate an ACH transfer the same day, which reaches your bank within one to three business days. Afterpay assigns each merchant a settlement period of between one and five business days in the merchant agreement, with bank ACH time on top, and says it periodically reviews merchants on longer periods to shorten them. Neither offers an expedited payout at any price.
Not really, and that is a design decision rather than a limit you can negotiate. Every Afterpay plan is interest-free to the shopper, so the merchant commission has to fund the whole cost of credit - which stops working as the ticket and the term grow. Affirm's longer plans charge the shopper 0-36% APR, and that consumer-funded interest is what lets it underwrite considered purchases over much longer terms. If your average order value is in the thousands, Affirm is the one built for it.
The provider does, in both cases. Affirm and its lending partners, and Afterpay respectively, approve the shopper, pay you upfront and carry the consumer credit and fraud risk. The catch is that neither runs on card-network chargeback rights. Affirm handles disputes under its own dispute resolution policy, and Afterpay can claw settlement back on a non-delivery dispute if you cannot evidence delivery within its stated window. Read both dispute regimes before you sign.
Usually yes. Block owns Square, Cash App and Afterpay, so Afterpay is built into that stack rather than added to it - a Square seller can offer it without a separate integration project or contract, and reaches Cash App shoppers at the same time. Affirm can still be added, but in that setup it is a third-party method with its own onboarding, and the convenience gap is real for a small business without engineering time to spend.
Affirm, clearly. It is listed on Nasdaq and reports every quarter, so you can read that it facilitated $50.2 billion of GMV in the fiscal year to 30 June 2026, up about 37%, across roughly 571,000 active merchants. Block folded Afterpay into its wider lending and commerce reporting and no longer breaks out standalone Afterpay figures, so its trajectory is not visible from outside. If you want to see a partner's numbers before committing volume to it, only one of these two shows them.
