Platinum Mastercard Rates and Fees

On the record for Platinum Mastercard Rates and Fees: a purchase APR of 12.49%–18%, no annual fee and a six-month 0% opening period, filed by Sun East Federal Credit Union. Against the 4,587 filings on this site, that rate lands around the 34th percentile.

The disclosed terms

This page covers the agreement Sun East Federal Credit Union filed for Platinum Mastercard Rates and Fees. It is issued on the Mastercard network and the filing runs one page.

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

This document discloses several products inside a single rate table. That means the numbers below are the ones the table contains, not necessarily the ones attached to this particular card — the filing itself is the only way to tell them apart.

The interest-free window

The filing discloses a 0% introductory rate running six months. For that window, balances covered by the promotion accrue no interest at all.

Roughly 458 of the 4,587 filings indexed here disclose a zero-percent introductory rate, so this is a real feature of the document but not a rare one.

Once the introductory period ends the rate becomes 18%, which turns a lingering $3,000 balance into approximately $591 of annual interest.

Put the other way round, the six-month zero rate is worth roughly $296 on a $3,000 balance relative to paying the go-to rate from day one — a real figure, but one that only materialises for someone who was going to carry that balance anyway.

The purchase rate in context

This is a tiered agreement: the filing discloses a purchase APR anywhere from 12.49% to 18%, a spread of 5.51 percentage points. Which end of that band applies is set by the issuer at account opening and the filing does not say how.

The floor of that band sits at about the 20th percentile of filed purchase rates; the ceiling sits at about the 34th. In corpus terms the same card can be cheap or expensive depending on how it is priced.

Because the rate is variable, the figure quoted is tied to an index and will drift with it. Nothing here is a fixed commitment.

To be precise about which number this is: the filing identifies it as the rate that takes over after the introductory period, not the introductory rate.

The cost of carrying a balance

Carry $5,000 on this card for a year without paying it down and the purchase rate alone generates roughly $986 in interest.

Measured against the 21.99% corpus median, the same $5,000 costs approximately $244 less per year here.

Broken down to a single thirty-day cycle, the same balance accrues roughly $74.50.

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

Penalty pricing and late fees

The maximum late fee is $36 — roughly the 58th percentile of the late fee ceilings disclosed across this index.

What the card costs before you borrow

The annual fee is $0. Roughly 75% of filings here that state a fee state zero, so the absence of one is unremarkable in this market.

Cash advances carry a cash advance fee of 2%.

A balance transfer costs $10 or 4% of the amount transferred, whichever is greater up front. The filing does not separately state the rate applied to transferred balances. Transferring $1,000 would cost roughly $40 at the door.

The no-interest path

Anyone clearing the statement balance inside 21 days pays no purchase interest at all under this filing. That is shorter than the 25-day corpus median.

The filing sets the minimum interest charge at zero — small balances are not rounded up to a floor.

How it sits in the issuer's own range

There are 4 filings from Sun East Federal Credit Union in this index.

What is outside the disclosure

Absent from the captured terms: a foreign transaction fee and penalty pricing. The original document is the place to look for any of these.

An agreement filing is not a marketing document. Rewards, perks, welcome offers and eligibility rules are not in it, are not in this dataset, and are therefore not discussed anywhere on this page.

Where the authority sits

This summary stands or falls on the linked PDF — one page. Agreements are amended over time, and the filing reflects the terms as submitted rather than as they stand today.

In short

18% is an unexceptional purchase rate in this collection, and the rest of the terms follow the same pattern. Because there is no annual fee, everything depends on the revolving behaviour: used as a payment instrument and cleared monthly, this agreement costs nothing. The multi-product table is the larger caveat: these numbers are the table's, not necessarily this card's.
