To get 20% cashback with PayPal Pay in 4, you must typically activate a specific “Pay Later” promotional offer within your PayPal account before making a purchase. While PayPal offers standard rewards, the 20% rate is usually part of a limited-time seasonal promotion (like those seen during Black Friday/Cyber Monday).

Here is the step-by-step process to find and use this offer:
1. Check for Eligibility
Not all users receive this offer. It is often targeted.
- Open the PayPal App or log in to the PayPal website.
- Navigate to the Rewards or Deals tab.
- Look for a banner that says 20% cash back on Pay Later purchases or similar.
2. Activate (Save) the Offer
You must “Save” or “Claim” the offer before you shop.
Click the Save Offer button on the deal page. If you don’t save it first, the cashback will not be applied to your transaction.
3. Choose a Qualifying Merchant
The offer usually works at most merchants that accept PayPal, but some exclusions (like gift cards or gambling) may apply. Ensure the merchant supports “Pay Later” options.
4. Select Pay in 4 at Checkout
- Select PayPal as your payment method at the retailer’s checkout.
- Once the PayPal login window opens, choose Pay Later and then specifically Pay in 4.
- Complete the transaction. You will pay the first 25% installment immediately.
Key Terms to Watch For
Cashback Cap
These offers are almost always capped. For example, a common limit is $250 total cashback, which means you only earn the 20% on the first $1,250 of your purchase.
Pending Period
Your cashback will appear as “Pending” in your Rewards Hub. It typically takes 30–90 days to become available for redemption (to ensure you don’t return the item).
Expiration
These high-value offers usually have a strict end date (e.g., December 8th or December 31st).
