Buy Now, Pay Later

Buy now, pay later (BNPL) is a payment arrangement that allows you to purchase something immediately and pay for it later.

Depending on the provider and agreement, payment may be made in a small number of installments, on a later date, or through another repayment schedule.

Terms, fees, interest, and eligibility vary between providers and agreements.

How BNPL works

Suppose you purchase an item for €300 using a BNPL arrangement.

You receive the item immediately, but instead of paying the full €300 at the time of purchase, you repay the amount according to the payment schedule.

For example, the €300 could be divided into three €100 payments.

The purchase represents €300 of spending, while the repayments determine when money actually leaves your bank account.

BNPL and spending

The full purchase amount can represent spending when the purchase is made, even if payment happens over several months.

For example:

  • September: €300 of spending.
  • September: €100 money out.
  • October: €100 money out.
  • November: €100 money out.

The three repayments should not be treated as three separate €100 purchases.

This distinction is important when analyzing spending and avoiding double counting.

BNPL and outstanding balances

A BNPL purchase can create an amount that remains to be paid.

As repayments are made, the outstanding amount decreases.

For example:

  • Purchase: €300
  • First payment: €100
  • Remaining amount: €200
  • Second payment: €100
  • Remaining amount: €100
  • Final payment: €100
  • Remaining amount: €0

Additional fees or interest, where applicable, can change the amount owed.

BNPL and Money In & Out

BNPL illustrates the difference between spending and money leaving an account.

The spending occurs when the purchase is made, while the associated money out may occur through several later payments.

Tracking the purchase and repayments separately helps maintain an accurate view of both spending and account movements.

BNPL vs credit cards

BNPL and credit cards can both allow you to pay for a purchase later, but they are different types of financial arrangements.

A credit card generally provides a revolving line of credit that can be used for multiple purchases.

A BNPL arrangement is generally tied to a specific purchase or repayment plan.

The exact structure depends on the provider and agreement.

BNPL and financial tracking

When tracking BNPL activity, it is useful to distinguish between:

  • The original purchase.
  • The amount spent.
  • The outstanding amount owed.
  • Individual repayments.
  • Money leaving the payment account.
  • Any interest or fees.

Keeping these events separate helps prevent installment payments from being counted as additional spending.
