You can change your Affirm payment plan, but only before your first payment is due

Once you've completed a purchase with Affirm, you have a window to modify your plan—but that window closes when your first payment is scheduled to come out. If you haven't made that first payment yet, you can log into your Affirm account, find the order, and select a different payment schedule. Affirm will show you the available options and how the new schedule changes your total cost and payment amounts.

After your first payment processes, you cannot change the plan itself. You can still pay early, skip a payment (if your plan allows it), or pay off the entire remaining balance at any time without penalty. But the number of payments and the payment dates are locked in once that first charge hits your account.

Key Takeaways

  • You can change your payment plan only before your first payment is due, by logging into your Affirm account and selecting a new schedule.
  • Once your first payment processes, the plan cannot be changed, though you can pay early or pay off the balance in full without extra fees.
  • Changing your plan may change the total amount you pay in interest or fees, so review the new terms before confirming.
  • If you want to cancel the purchase entirely rather than change the plan, you must do that before the first payment is due.

How to change your plan before the first payment

Log into your Affirm account on the Affirm website or mobile app. Go to "Orders" or "My Purchases" and find the transaction you want to modify. Tap or click on that order to open its details. You should see a button or link that says "Change Payment Plan" or "Modify Plan"—the exact wording varies depending on whether you're on mobile or desktop.

Affirm will display all available payment schedules for that purchase. These options depend on the merchant and the purchase amount, so not every plan that was available at checkout may still be available. Review each option: the number of payments, the payment dates, the payment amount, and the total cost including any interest or fees. Select the plan you want and confirm the change. Your new schedule takes effect when ready, and your first payment date will shift to match the new plan.

What happens to interest and fees when you change plans

Affirm's interest charges depend on the length of your plan. A shorter plan (like 3 months) typically costs less in total interest than a longer plan (like 12 months), because you're paying off the balance faster. When you change from a longer plan to a shorter one, your total interest may decrease. When you change from a shorter plan to a longer one, your total interest may increase.

Some Affirm plans charge no interest at all—these are usually the shorter plans or plans offered by specific merchants. If you switch to a plan that does charge interest, you'll pay more overall. If you switch to a plan with no interest, you'll pay less. Always compare the "Total Amount" or "Total Cost" figure shown for each plan option, not just the individual payment amount.

Why you cannot change your plan after the first payment

Once Affirm processes your first payment, the loan terms are considered active and locked. Changing the plan at that point would require recalculating interest, adjusting payment dates, and potentially renegotiating the terms with the merchant. Rather than allow mid-loan modifications, Affirm treats the plan as final after that first charge.

This is why the change window is narrow: you have from the moment you complete checkout until the night before your first payment is due. If you miss that window, your only options are to pay early, pay in full, or continue with the plan as scheduled.

Paying early or paying off the balance without changing the plan

If you cannot change your plan but want to reduce what you owe, you can make extra payments or pay off the entire remaining balance at any time. Affirm does not charge prepayment penalties or early payoff fees. Log into your account, find the order, and look for an option to "Pay Now" or "Pay in Full." You can pay any amount up to the full remaining balance.

Paying early does reduce the total interest you'll pay, because you're carrying a lower balance for less time. However, it does not change the payment plan itself—your scheduled payment dates remain the same unless you choose to skip a payment (if your plan allows skipping). Check your plan details to see whether skipping payments is an option for your specific loan.

Canceling the purchase entirely instead of changing the plan

If you want to cancel the Affirm purchase rather than modify the plan, you must do so before your first payment is due. Canceling means the loan is terminated and you owe nothing to Affirm—but you may still owe the merchant if you've already received the goods or services. Contact Affirm support through the app or website to request cancellation, and confirm with the merchant about their return or cancellation policy.

After your first payment has processed, canceling the loan is no longer an option. At that point, you're committed to the payment plan, though you can still pay it off early without penalty.

What to do if you cannot find the change plan option

If you're logged into your Affirm account and cannot see a "Change Payment Plan" button on your order, it usually means one of three things: your first payment has already processed, the merchant does not allow plan changes for that particular purchase, or there is a technical issue with the app or website.

Check the payment due date shown on your order. If it says "Payment Due Today" or a date in the past, your first payment has likely already been charged. If the due date is in the future and you still cannot find the option, try logging out and back in, or try accessing your account from a different device or browser. If the problem persists, contact Affirm support directly through the app—they can tell you whether the plan is still changeable and help you modify it if it is.

Frequently Asked Questions

Can I change my Affirm plan after I've made the first payment?

No. Once your first payment processes, the plan is locked and cannot be changed. You can pay early or pay off the balance in full, but you cannot modify the payment schedule or number of payments.

Will changing my plan affect my credit score?

Changing your plan before the first payment does not affect your credit, because the loan has not yet been reported to credit bureaus. Once your first payment processes and the loan is active, your payment history will be reported, but changing payment terms after that point is not possible.

What if the new plan I want is not showing up as an option?

Not all plans available at checkout remain available later. The merchant, the purchase amount, or Affirm's current lending criteria may limit which plans you can switch to. Contact Affirm support to confirm whether other plans are available for your purchase.

Can I skip payments if I change to a longer plan?

Whether you can skip payments depends on your specific plan and Affirm's policies at the time of purchase. Check your plan details in the app to see if skipping is allowed. Changing your plan does not automatically add or remove the skip option.

If I pay off my Affirm loan early, do I get a refund on interest?

Affirm does not refund interest when you pay early. However, paying early stops additional interest from accruing on the remaining balance, so you pay less total interest than if you had kept the original schedule.
