The disclosed terms

The document behind this page is Celtic Bank's filed agreement for Indigo Mastercard Cardholder Agreement 662. The filing runs 13 pages, and It is issued on the Mastercard network.

The filing is explicit about a purchase rate, a late payment maximum, a foreign transaction fee and a grace period. No figure appears for a cash advance rate, a balance transfer rate and a penalty rate.

The purchase APR against the corpus

Set beside the rest of the index, the purchase APR of 35.9% lands at the 91st percentile; it sits in the expensive end of the corpus.

Translating the rate into money

A $1,200 balance left untouched for twelve months accrues about $518 in interest at this purchase rate.

A card priced at the corpus median of 21.99% would charge roughly $295 on that balance. This one charges about $223 more per year.

That maths assumes a static balance and nothing else — no payments, no additional purchases, no fees folded in.

Paying in full

Anyone clearing the statement balance inside 25 days pays no purchase interest at all under this filing. That matches the 25-day median across the corpus almost exactly.

Where interest applies at all, the filing bills at least $1. On a tiny balance that floor can dwarf the rate itself.

Penalty pricing and late fees

On the fee side, a late payment can cost up to $41, which is around the 89th percentile here.

What the card costs before you borrow

Spending abroad costs an extra 1% — about $50 on $5,000 of purchases, independent of interest.

Against the rest of Celtic Bank's filings

92 separate Celtic Bank filings appear in the corpus. Their disclosed purchase rates run from 22.49% to 35.9%, and this one at 35.9% is more expensive than 25 of them.

What you cannot learn from the filing

Absent from the captured terms: anything about cash advances, balance transfer terms, an annual fee and penalty pricing. The original document is the place to look for any of these.

It is worth being explicit about scope: these filings record terms and pricing. They say nothing about rewards programmes, cardholder benefits, promotional offers or who the issuer will approve, and this review does not speculate about any of it.

In short

This is an expensive agreement by the standards of the corpus, driven by a 35.9% purchase rate that is inert for a transactor and punishing for a revolver.
