Calculation

Calculated automatically from your Klarna data. See the At a glance summary above for what the metric tracks and the worked example below for a typical reading.

​

Worked example

“Helle Mode” 7-day Klarna decline breakdown. What the merchant should notice:

1. Address verification at 17% is the only actionable category. Improve checkout address validation (Google Address Autofill, Loqate); recover roughly 60-70% of these.
2. Insufficient data + Existing debt = 60% of declines. Both customer-side; no merchant fix.
3. Fraud flag at 11% is low (good). Above 20% suggests merchant attracts higher-fraud-risk traffic.

Reconciling against the vendor’s own dashboard

Where to look: Klarna does not publicly expose per-decline-reason breakdowns due to consumer-credit privacy. The Merchant Portal aggregates into broad categories. Why our number may differ:

​

Known limitations / merchant FAQs

Why are reasons so vague? Consumer-credit-privacy regulation. Klarna cannot disclose specific risk signals to the merchant. Address verification, can I improve it? Yes. Implement Google Address Autofill, Loqate, or similar; clean addresses recover 60-70% of these. Existing debt, anything I can do? No. The customer has open Klarna balances elsewhere. They need to settle before increasing exposure. Fraud flag at 5% suddenly jumped to 25%, what gives? Targeted fraud attempt at the merchant. Klarna’s risk model caught it. The merchant should review web traffic for campaign anomalies. Slice it has a unique decline reason? Yes: SLICE_IT_CREDIT_CHECK_FAILED. Customer chose Slice it but didn’t pass the harder credit check. They can retry with Pay in 4 or Pay in 30.
