You Know Your Credit Card Balance. Do You Know What It Costs You Per Day?

Most people know roughly what they owe on their credit cards. Few know what that debt actually costs them while they sit on it.

That's the number that changes behavior.

I built a debt tracker into PetroTins for exactly this reason. You add your card — balance, credit limit, APR — and it tells you what you're paying for that debt in interest: per month, per year, and per day. Not someday when you get the statement. Right now.

A $6,000 balance at 24% APR doesn't feel that bad until you see it's costing you $3.95 today. And tomorrow. And every day after that whether you think about it or not. That daily number has a way of cutting through the denial that monthly minimums let you maintain.

There's a version of this that's even worse than credit card debt, and millions of people are living it right now without realizing it.

Imagine you have $40,000 in student loans at 7% interest. That's $233 in interest every single month. If your payment is $200 — which feels responsible, you're paying every month — you are not paying down your loan. You are going backwards. The balance at the end of the month is higher than it was at the start. Next month you owe interest on a slightly larger number. And the month after that.

A forever loan. You can pay faithfully for years and owe more than you started with.

TradfiTins shows you that number. Not buried in a loan servicer portal after three clicks — right on your dashboard, next to your income and expenses. The moment you see that your monthly interest exceeds your monthly payment, you know you have a different problem than you thought you did.

Beyond the cost visibility, you get a utilization bar for credit cards, an entry log for payments and charges that updates your balance automatically, and a full cash flow summary across every debt and income source you track. No spreadsheet, no mental math.

The point is to make the cost of debt impossible to ignore so you're making intentional decisions rather than just paying the minimum and moving on.
