What the document actually states

Celtic Bank filed this agreement for Indigo Mastercard Cardholder Agreement 663 with the Consumer Financial Protection Bureau. It is issued on the Mastercard network and the filing runs 13 pages.

On the record here: 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 rate in context

The purchase APR of 35.9% places this agreement around the 91st percentile of the set — it is well above what most issuers disclosed.

What the rate means in dollars

Carry $1,000 on this card for a year without paying it down and the purchase rate alone generates roughly $432 in interest.

A card priced at the corpus median of 21.99% would charge roughly $246 on that balance. This one charges about $186 more per year.

Month to month it reads as about $29.93 per cycle on that balance.

There is also a floor: the filing sets a minimum interest charge of $1, so any cycle that accrues less than that is billed at $1 anyway.

Treat this as an illustration of what the disclosed rate does, not as a projection of a real account, which would be shaped by payments and by the fees described elsewhere in the filing.

The grace period

The filing gives 25 days' grace on purchases, meaning a statement balance paid in full within that window attracts no interest.

A minimum interest charge of $1 applies in any cycle where interest is due, which makes very small revolving balances disproportionately expensive.

The downside terms

The maximum late fee is $41 — roughly the 89th percentile of the late fee ceilings disclosed across this index.

Fees, and what triggers them

The filing sets a 1% foreign transaction fee, which adds roughly $10 to $1,000 spent outside the United States.

How it sits in the issuer's own range

This is one of 92 Celtic Bank agreements collected here. The issuer's own range is 22.49%–35.9%. At 35.9%, this agreement is dearer than 25 of its siblings.

What you cannot learn from the filing

The disclosure parsed here does not state anything about cash advances, balance transfer terms, an annual fee and penalty pricing. Those gaps are gaps in what could be read from the filing, and the PDF may well address them in prose the rate table does not capture.

What this analysis can address is bounded by the filing: rates, fees and the terms around them. Everything a card issuer might advertise — rewards, benefits, bonuses, who qualifies — falls outside the document and outside this review.

The document itself

Everything here is a reading of the filed agreement, 13 pages of it, which is linked above and which governs. Terms also change between filings, so the date on the document matters.

In short

The defining fact about this filing is the purchase rate: at 35.9% it is in the expensive band of this corpus, and that cost only materialises for someone who revolves a balance.
