How long you have before PayPal Credit interest kicks in depends on your purchase amount. You have 6 months to pay off purchases of $149 or more before interest kicks in. For purchases under $149, interest starts accruing immediately with no grace period. This means if you do not pay your entire balance in full by the payment due date each month, the standard variable APR applies to the unpaid balance from the transaction date. Any balance you carry will generate interest charges on your next statement.
The 6-month PayPal Credit interest window only applies to purchases of $149 or more
When you use PayPal credit at checkout and the total transaction amount meets the $149 threshold, the system automatically triggers a promotional financing offer of 6 months no interest. Synchrony Bank, which issues the PayPal Credit account, sets this threshold. You can confirm the current figure on the official PayPal Credit terms page. The 6-month clock starts ticking from the transaction date, the exact day the payment is authorized, not from the date the item ships or appears on your statement. For example, if you buy a laptop on March 15, your promotional deadline is September 15, regardless of when the laptop arrives or when your monthly statement closes. If the purchase amount is even one cent below the threshold, the offer does not activate, and you can avoid interest on that purchase only by paying your entire statement balance in full by the payment due date each month.
What happens if you don't pay in full by month six
If you fail to pay the entire promotional amount by the end of the sixth month, deferred interest is calculated from the original purchase date and added retroactively to your outstanding amount. This is the costliest misunderstanding people have: the interest does not start at month six. It is applied as if you never had a promotional period at all. Depending on your APR and purchase amount, that retroactive interest could be substantial, even if you paid most of the sum before the deadline. The only way to avoid this penalty is to ensure the full original purchase amount is paid off before the promotional window closes.
Purchases under $149 and the standard variable rate
For any transaction below $149, there is no interest-free window at all. Synchrony Bank sets the standard variable APR based on the Prime Rate, and for new accounts it is approximately 29.89% (as of 11/1/2025 or 1/1/2026). This means if you do not pay your statement balance in full by the due date, interest accrues daily on the outstanding sum starting from the transaction date. If you use PayPal credit for a grocery order and do not pay the statement total in full, you will see interest charges on that amount from the day you spent it. For small amounts, the only way to avoid interest is to pay the total in full before the statement due date.
How minimum payments trick you into thinking you are safe
PayPal Credit requires a minimum monthly payment. Synchrony Bank calculates it as the greater of a small fixed floor or the total of any interest, fees, and 1% of the principal. If you make only that minimum payment each month, you will not clear the amount before the 6-month promotional period ends. For a purchase of several hundred dollars, the minimum payment in month one might be tiny, leaving almost the entire sum unpaid. Even after five minimum payments, you would still owe the vast majority at the deadline, triggering retroactive interest on the original purchase. To beat the deadline safely, divide the purchase amount by six and pay that exact slice each month. You can make these payments by logging into your PayPal account and selecting the PayPal Credit card, or by consolidating funds from another source if needed. Note that if you use a linked bank account or debit card to make the payment, there is no additional charge. If you pay via a credit card through the PayPal interface, additional fees may apply, so check your payment method carefully. For smaller purchases you might avoid interest entirely by using stores that accept PayPal Pay in 4, which splits costs into four automatic installments. You can also transfer money from a credit card to PayPal to consolidate funds before making your payment.
This is the only PayPal Credit page that explains the promotional clock starts on the authorization date, not the shipping date, and that a single cent below the $149 threshold silently kills the offer before you even leave the checkout.
