What Affirm Is and How It Works

Affirm is a buy-now-pay-later service that lets you split a purchase into multiple payments instead of paying the full amount upfront. When you check out at a store or online retailer that offers Affirm, you can choose to pay in installments rather than using a credit card or debit card for the whole purchase at once. Affirm handles the transaction with the merchant, and you repay Affirm over time according to the payment schedule you select.

The service works through a mobile app or website. At checkout, you enter your personal information, and Affirm performs a soft credit check — this means it looks at your credit but does not report the inquiry to credit bureaus the way a hard pull does. Based on that check, Affirm shows you the payment plans available for that specific purchase. You pick the plan that works for your budget, confirm it, and the purchase goes through. Your first payment may be due when ready or within a few weeks, depending on the plan.

Affirm is not a credit card. You cannot use it to withdraw cash, and you cannot use it everywhere — only at retailers that have partnered with Affirm. The company makes money by charging merchants a fee, not by charging you interest on most plans, though some longer plans do include interest.

Key Takeaways

  • Affirm splits your purchase into 2 to 48 monthly payments, and you see all available plans and their costs before you confirm the purchase.
  • Many Affirm plans charge no interest, but longer payment periods may include interest, and you will see the total cost upfront.
  • If you miss a payment, Affirm reports it to credit bureaus and may charge a late fee, which affects your credit score.
  • Affirm is only available at retailers that partner with the service, and you cannot use it for cash withdrawals or bill payments.
  • Returning an item you bought through Affirm cancels the remaining payments, though the refund process depends on the merchant's policy.

Payment Plans and Interest

Affirm offers several standard payment options. The most common are 3-month, 6-month, and 12-month plans, though some retailers offer plans as short as 2 months or as long as 48 months. For many purchases, Affirm advertises "0% APR" plans — these have no interest, and you pay only the purchase price divided evenly across the months. A $300 purchase on a 3-month plan costs $100 per month, with no extra charge.

Longer plans often include interest. If a plan shows an interest rate — for example, 10% APR — Affirm calculates the total interest and adds it to the purchase price. You will see the exact total cost, the monthly payment amount, and the interest rate before you confirm the purchase. There is no hidden math. A $300 purchase on a 12-month plan at 10% APR might total $315.87, so your monthly payment would be about $26.32.

The interest rate you receive depends on your credit profile. Two people buying the same item may see different rates and different available plans. Affirm does not publish a standard rate table — it calculates rates individually based on the soft credit check it performs at checkout.

Late Payments and Credit Impact

If you miss a payment, Affirm charges a late fee and reports the missed payment to credit bureaus. The late fee amount varies, but Affirm typically charges between $10 and $37 depending on your payment plan and history. A single missed payment can lower your credit score, and multiple missed payments will damage it more severely.

Affirm reports your account activity to Equifax, Experian, and TransUnion — the three major credit bureaus. This means on-time payments can help your credit history, but missed payments will appear on your credit report and stay there for seven years. If you fall significantly behind, Affirm may send your account to a debt collector.

If you are having trouble making a payment, contact Affirm directly through the app or website. The company sometimes works with customers to adjust payment schedules or pause payments temporarily, though this is not may provide and depends on your account history.

Where You Can Use Affirm

Affirm is available at hundreds of online retailers and some physical stores, but the list is not universal. Major retailers that accept Affirm include Amazon, Target, Walmart, Best Buy, Sephora, and many furniture and home goods stores. You can check whether a specific retailer accepts Affirm by looking for the Affirm logo at checkout or by searching the retailer's name in the Affirm app.

Affirm cannot be used for groceries, gas, utilities, insurance, or other recurring bills. You also cannot use Affirm to pay off credit cards, take cash advances, or withdraw money from ATMs. The service is designed only for retail purchases of physical or digital goods.

Some retailers limit the minimum or maximum purchase amount for Affirm. For example, a store might require a purchase of at least $50 to use Affirm, or might not allow Affirm for purchases over $10,000. These limits vary by merchant and are shown at checkout.

Returning Items and Canceling Payments

If you return an item you bought through Affirm, the remaining payments on that purchase are canceled. The refund goes back to Affirm, not directly to your bank account, and Affirm credits your account. You then have the option to use that credit toward another purchase or request a refund to your original payment method.

The timing of the refund depends on the merchant's return policy and how quickly they process the return. Some retailers issue refunds within a few days; others take two to three weeks. Once the merchant sends the refund to Affirm, Affirm typically credits your account within one business day. If you requested a refund to your bank account, that transfer may take an additional three to five business days depending on your bank.

If you have already made some payments before returning the item, those payments are not refunded — you keep the credit for the amount you paid. For example, if you bought a $300 item on a 3-month plan and returned it after one payment, you would have a $200 credit in your Affirm account.

Fees and Costs

Affirm does not charge an upfront fee to use the service. You pay only the purchase price (plus interest if your plan includes it) and any late fees if you miss a payment. There is no annual membership fee, no process fee, and no fee for paying on time.

Late fees are the main cost beyond the purchase itself. As mentioned, these typically range from $10 to $37 per missed payment. Some plans may also include a small origination fee or other charges, but Affirm shows the complete cost breakdown before you confirm your purchase, so you will know the exact total you owe.

If your account goes to collections, you may face additional collection agency fees, though these are separate from Affirm's fees and depend on the collector's practices.

How Affirm Affects Your Credit

The soft credit check Affirm performs at checkout does not appear on your credit report and does not lower your credit score. However, once you open an Affirm account and begin making purchases, Affirm reports your payment history to credit bureaus. On-time payments show up as positive account activity, which can help your credit score over time. Missed payments and late accounts damage your score.

Affirm accounts appear on your credit report as installment loans. This is different from credit card accounts, which are revolving credit. Having a mix of installment and revolving credit can be beneficial for your credit score, so using Affirm responsibly may help your overall credit profile.

If you close an Affirm account or pay off all your purchases, the account remains on your credit report for up to seven years. This does not hurt your score — closed accounts with a positive payment history actually help it.

Frequently Asked Questions

Can I use Affirm if I have bad credit?

Affirm does not have a strict credit score requirement, and the company approves some customers with lower credit scores. However, approval is not may provide, and the plans and interest rates you see depend on your credit profile. If you are denied, you can try again at a different retailer or wait a few months and try again.

What happens if I pay off my Affirm plan early?

You can pay off your remaining balance at any time through the Affirm app without penalty. There is no prepayment fee. Paying early stops future interest from accruing if your plan includes interest, though you still owe the interest that has already been calculated into your plan.

Does Affirm show up on my credit report?

Yes. Affirm reports your account and payment history to Equifax, Experian, and TransUnion. On-time payments help your credit, and missed payments hurt it. The account appears on your report as an installment loan.

Can I use Affirm for online and in-store purchases?

Affirm works for most online purchases at partnered retailers. Some physical stores also accept Affirm, but availability varies by location and retailer. Check the Affirm app or look for the Affirm logo at checkout to see if a specific store accepts it.

What if I dispute a charge or think there was an error?

Contact Affirm through the app or website to report a problem. Affirm investigates disputes and can adjust your account if an error occurred. The process typically takes a few business days, and Affirm will notify you of the outcome through the app.
