Why a payment fee exists and how to compare total cost

A fee on a phone payment feels like a penalty. Sometimes it is just a toll for a path that is not the provider's own checkout. Sometimes it is hidden until the last click. You can compare the paths without calling one of them the cheapest. "Cheapest" depends on the credit amount, the fixed part of the fee, and whether the credit actually posts.

This article explains the shape of Northline's fee and a way to compare totals. The numbers themselves are on the Fees page, calculated by the server function. If this article and that table ever disagree, trust the Fees page and tell us.

What the fee is paying for

A guest page has to validate a number, price an order, hand card data to a processor, store a reference, and ask a partner to post a credit. Those steps cost money even when they fail. A fee is how that cost is shown to you instead of being buried inside a worse exchange rate or a rounded-down credit.

The fee is not the phone credit. On Northline the credit is the amount you type. The fee is added. A provider's own checkout may have a different fee, or none, because you are already their customer. Using their page is often the simplest path when you can sign in.

Percentage plus a fixed amount

Northline's rule is a percentage of the credit, rounded to the nearest cent, plus a fixed amount, with a floor of one dollar. Small credits hit the floor. Larger credits are dominated by the percentage. That is why a single example at one dollar amount does not describe the schedule.

A promo code, when the server accepts it, takes a percent off the fee only. The result is rounded to the cent. The fee after the promo still cannot be under one dollar. The credit on the phone number does not shrink.

How to compare two totals

Write three lines for each option: credit the phone should receive, fee, total charged to the card. Use the same credit on each line. If one option posts a smaller credit because it takes the fee out of the airtime, note that. You are no longer comparing equal credits.

Then ask a fourth question: if the credit never shows, do you get the card charge back? A lower total that you cannot recover is not automatically better. Northline's written rule is that a captured payment is refunded when the credit is not posted. Issuer timing still varies. We do not promise a day count beyond the range on the refunds page.

What not to compare

Do not compare a fee percentage with a flat dollar fee without doing the arithmetic for your amount. Do not compare a prepaid credit with a postpaid invoice. Do not treat a waitlist signup as a price. The waitlist does not charge a card.

• Same credit amount on every option.
• Fee and card total written down.
• A sentence on the site about refunds if the credit fails.
• The provider's own checkout included in the comparison when you can use it.

If the numbers look wrong

The server total is the one that would be charged when payments are open. A total you edit in the browser is ignored. If the Fees page and the review step disagree, do not continue. Contact us with the amounts you saw and the time. Do not send a card number.

Work one example by hand so the shape is familiar. Take the credit you actually plan to buy. Apply the percentage, round to the cent, add the fixed part, then raise the result to one dollar if it is lower. If a promo is accepted, take ten percent of that fee, round to the cent, and stop if the fee would fall under a dollar. The Fees page already does this. Doing it once yourself tells you whether a quoted total is in the right neighborhood before you compare it with the provider's own checkout. Repeat the arithmetic if you change the credit. A fee that looked small on a forty-dollar example can hit the one-dollar floor on a five-dollar credit, which changes the comparison.

Write the comparison in four lines. Line one is the credit the phone should receive. Line two is the fee from the schedule, including the one-dollar floor. Line three is the card total. Line four is what happens if the credit never posts. Fill those lines for the provider's own page and for this site. If a promo applies, recompute line two and line three. Do not leave the promo as a feeling that the price got better. The server either accepts the code or it does not. A code that fails should leave the original fee in place, not a guessed discount. When you have both sets of lines, the choice is arithmetic plus the refund rule, not a slogan. Keep the sheet with the order reference if you pay. It explains the card statement later, when the statement shows the total and the phone shows only the credit. Those two numbers are supposed to differ by the fee.
