Affirm Review

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.

Estimated annual cost at three realistic processing volumes, using Affirm’s published online rate plus monthly fees. Real costs vary with average transaction size, chargeback rate, and any negotiated terms.

What Affirm is, from a merchant's side of the counter

Affirm is a lender that sits in your checkout. A shopper picks Affirm instead of a card, Affirm underwrites them in real time, you are paid the full basket up front minus a merchant fee, and Affirm collects from the consumer over one to four short instalments or over monthly instalments at an APR between 0% and 36%. It was founded in 2012 by Max Levchin, Nathan Gettings, Jeffrey Kaditz and Alex Rampell, is headquartered at 221 Main Street in San Francisco, has traded on Nasdaq as AFRM since January 2021, and reincorporated from Delaware to Nevada on 1 July 2025.

The scale is not in doubt. For the fiscal year ended 30 June 2026, Affirm reported $50.2 billion of gross merchandise volume, up 37% year on year, across approximately 571,000 active merchants and 27.8 million active consumers, who transacted an average of 7.0 times each. Total revenue for the year was $4.26 billion, up 32%, of which merchant network revenue — the fees merchants pay — was $1.15 billion.

It is also, finally, profitable at the operating line: $417 million of operating income in FY2026 against an $87 million operating loss the year before. The much larger reported net income of $1.93 billion is not an operating result — it includes a non-cash income tax benefit of roughly $1.4 billion from releasing a valuation allowance against domestic deferred tax assets, which is an accounting recognition that Affirm now expects to earn enough to use them, not $1.9 billion of earnings.

The bargain is different from card acceptance

Two things about Affirm are structurally better for a merchant than taking a card, and they are the reason the fee can be defended. First, the credit risk is Affirm's: if the borrower stops paying, that is Affirm's loss and there is no receivable on your books. Second, Affirm's own filings state it bears the risk of consumer fraud in transactions involving Affirm, a consumer and a commercial partner, and that it generally has no recourse to the merchant to collect. On a card, friendly fraud is your problem. Here it is not.

What remains yours is the merchandise dispute — non-delivery, damage, a return you did not process. Affirm adjudicates it, and if it resolves in the consumer's favour you reimburse the amount refunded. Third-party guides describe a response window and a fee on lost disputes; those specifics are not published by Affirm, so get them from your own agreement rather than from a comparison site.

What it costs, and why the two public numbers disagree

Affirm publishes no merchant pricing. Its filings say only that merchant fees depend on the individual arrangement with each merchant, vary by loan terms and product, and are generally larger on 0% APR financing. Two public numbers exist and they look contradictory until you understand what each measures.

Affirm's own merchant network revenue was 2.3% of gross merchandise volume in FY2026, down from 2.4%. That is a blended figure across everything, and it is dragged down by Affirm Card — a direct-to-consumer product now representing about 15% of Affirm's transactions and 5.2 million active cardholders, on which merchants pay Affirm nothing. Separately, third-party surveys of merchants in the $1-10 million revenue band report per-transaction fees between roughly 4.3% and 8%, with a median near 6%. That range reflects negotiated integrated merchants, weighted toward promotional 0% APR financing.

The practical reading: 2.3% is what Affirm earns on average; something in the mid single digits is what an integrated merchant running promotional financing should expect to be quoted. Both figures are attributed rather than universal, and neither substitutes for your own quote.

The product mix tells you where the money is

In FY2026, interest-bearing monthly instalments were 70% of Affirm's volume, Pay-in-X (one to four 0% APR instalments) 16%, and 0% APR monthly instalments 14%. The two 0% products are the ones growing fastest — Pay-in-X up 50% and 0% monthly up 46% — and they are also the products Affirm says carry the larger merchant fee, because the merchant is buying down the consumer's interest.

That is the trade-off in one line. The offer that converts a $2,400 mattress is 0% for 24 months, and that offer is the expensive one. Merchants who add Affirm and then default to the interest-bearing option because it is cheaper often see much less conversion lift and conclude BNPL does not work for them. It is worth modelling the promotional offer explicitly against your gross margin before deciding.

The consumer reputation is your problem too

Affirm's BBB profile is A+ and accredited since March 2020. Its Trustpilot score is 1.7 out of 5 across roughly 7,700 reviews. Both are true, and the gap is mostly about who bothers to write. The Trustpilot themes are consistent: support that cannot be reached, refunds that take too long to reflect against an outstanding loan, account freezes, and — most often — shock at the APR offered, with borrowers reporting high-twenties and low-thirties rates despite believing they had good credit. Third-party analysis of CFPB data reports 543 personal-loan complaints against Affirm in 2024, most commonly about payments.

None of this is merchant feedback. It matters anyway, because the borrower is your customer. When a refund has not appeared against their loan balance, they call the shop that sold them the thing. Budget support time for it, make sure your returns process notifies Affirm promptly, and if you promote Affirm in marketing, be explicit about the APR range rather than leaning on the 0% headline.

Litigation

Kusnier v. Affirm Holdings, a putative securities class action filed in December 2022 in the Northern District of California, alleged that Affirm made misleading statements about whether its business model was vulnerable to interest rate changes. The court dismissed it twice with leave to amend, resolved a reconsideration motion in Affirm's favour in August 2025, and dismissed the action with prejudice on 30 September 2025. Plaintiffs appealed to the Ninth Circuit on 29 October 2025; briefing is complete and the parties await oral argument. Three related shareholder derivative actions — Quiroga, Jeffries and Vallieres v. Levchin — remain on file, with Quiroga stayed by agreement.

Nothing here has been decided against Affirm, and none of it touches merchant operations. Affirm is also supervised by the CFPB as a consumer lender, which is a description of the category rather than a mark against the company.

How to decide

Run the arithmetic on one product line before signing anything. Take your average order value, your gross margin, and the merchant fee you are quoted for the 0% offer you would actually promote. Work out the incremental conversion you would need for the offer to pay for itself, then check that number against your abandoned-cart data. For high-ticket considered purchases the gap usually closes easily. For a $40 basket it does not, and adding Affirm just makes existing volume more expensive.

Affirm earns a B-. The merchant proposition is real — funded up front, no credit risk, no fraud liability on approved transactions, and the biggest BNPL consumer network in the US — but the price is unpublished and high, the best-converting product is the costliest, and the consumer service record generates work that lands on your side of the counter.
