Buy Now, Pay Later (BNPL) services have completely changed how people shop online and in stores. Instead of paying everything upfront or relying on high-interest credit cards, shoppers can now split purchases into smaller, manageable payments. Among all BNPL providers, two names dominate the market: Klarna and Affirm.
Both companies allow consumers to finance purchases over time, but they operate in very different ways. Klarna is best known for short-term, interest-free installment plans, while Affirm focuses on longer-term financing with clear, upfront pricing.
If you’re trying to decide between Klarna and Affirm, this guide breaks down everything you need to know—from fees and credit impact to real-world use cases—so you can choose the best option for your financial situation.
What Is Buy Now, Pay Later (BNPL)?
Buy Now, Pay Later is a form of short-term financing that lets consumers purchase items immediately and pay for them over time. Instead of paying the full price at checkout, you agree to a payment schedule, often with zero interest if payments are made on time.
BNPL has become extremely popular because it:
-
Makes large purchases more affordable
-
Offers transparent pricing compared to credit cards
-
Allows fast approvals with minimal credit checks
-
Integrates directly into online and in-store checkout systems
Klarna and Affirm both fall under the BNPL category, but they serve different types of shoppers and financial needs.

Now let’s look at each service in detail.
How Klarna Works
Klarna is one of the world’s largest BNPL providers, especially popular in Europe and the United States. It is designed to make short-term purchases easier by offering flexible payment options at checkout.
Klarna Payment Options
Klarna offers three main ways to pay:
1. Pay in 4
You split your purchase into four equal payments. The first payment is due at checkout, and the rest are automatically charged every two weeks. There is no interest if you pay on time.
2. Pay in 30 Days
You receive your items first and pay the full amount within 30 days. This option is useful for trying items before committing to them.
3. Monthly Financing
For larger purchases, Klarna offers longer-term financing that can last from 6 to 36 months. Some plans include interest, depending on the retailer and your credit profile.
Klarna Fees and Costs
Klarna makes money primarily through merchant fees, but users may still face some charges.
-
Interest: Most Pay in 4 and Pay in 30 plans are interest-free. Monthly financing may include interest.
-
Late fees: If you miss a payment on Pay in 4, Klarna may charge a late fee.
-
No hidden fees: Klarna shows all costs upfront.
Klarna is best when you want to split a small or medium-sized purchase into short-term payments without interest.
Does Klarna Affect Your Credit Score?
Most Klarna plans use a soft credit check, which does not impact your credit score. However, some longer-term financing plans may involve a credit check, and missed payments could be reported to credit bureaus.
For short-term plans, Klarna is generally low-risk from a credit standpoint.
How Affirm Works
Affirm is built around transparent, long-term financing. Instead of short installment plans, it offers structured loans with a clear monthly payment and interest rate.
Affirm Payment Structure
When you use Affirm, you choose a payment plan at checkout. These plans usually last from 3 to 60 months. You see the exact amount you will pay each month and the total cost of the loan before confirming.
Affirm does not charge late fees. If you miss a payment, interest continues to accrue, but you won’t be penalized with extra charges.
Affirm Fees and Interest
Affirm’s pricing model is different from Klarna’s.
-
Interest rates: Ranges from 0% to 36% APR depending on the retailer and your credit profile.
-
No late fees: You will never be charged for paying late.
-
No hidden charges: The total cost is shown upfront.
Affirm is designed for customers who need longer repayment terms and predictable monthly payments.
Does Affirm Affect Your Credit Score?
Affirm uses a soft credit check when you apply, so your credit score is not affected by the application. However, many Affirm loans are reported to credit bureaus. Making on-time payments can help build credit, while missing payments can hurt it.
This makes Affirm more similar to a traditional loan than a short-term BNPL product.
