How to use this calculator

Open your most recent statements for each credit card you carry a balance on. Each statement shows the four numbers you need: current balance, APR, minimum payment due, and credit limit. Enter one card at a time, then click add another card for each additional one. The credit limit field is optional. If you leave it blank, everything else still works, you just will not see your utilization ratio.

The snapshot updates as you type. The first number to look at is the burn rate block at the top. That tells you how much interest your balances are generating per day, per month, and per year at today's APRs. That number is real money leaving your wallet for nothing in return. The 12 month projection below shows where you land if you keep paying only the stated minimums and add no new charges. If that number is higher than today's balance, your minimums are not covering interest and the debt is growing.

Why the daily burn rate matters more than the total

The total balance is the number that scares people, but the daily interest burn is the number that should motivate them. A total balance feels like a one time problem to solve. A daily burn rate feels like a meter running. Watching $4 or $6 or $10 evaporate from your accounts every single day, whether you sleep, eat, or skip the cable bill, is what makes credit card debt feel real. That is what this snapshot is built for.

Once you have seen the number, the next step is to flatten the curve. Paying above the minimum on the highest APR card is the math optimal move. Paying off the smallest balance first is the psychology optimal move. Both work, and the Debt Payoff Calculator linked above will show you the dollar difference between the two strategies on your exact set of debts.

Frequently Asked Questions

Is this calculator a tracker?

No. This is a point in time snapshot based on the numbers you enter right now. Nothing is saved between sessions. If you want to see your numbers again later, just come back and enter them in fresh.

What is a weighted average APR?

A weighted average APR accounts for the size of each balance, not just the rates. A $9,000 balance at 26% and a $1,000 balance at 12% give you a weighted average closer to 25%, because most of your debt sits on the higher rate card. This is a more accurate picture than a simple average of the rates.

How is the daily interest burn calculated?

For each card, the calculator multiplies your balance by the APR, then divides by 365 to get the daily interest amount. Those daily amounts are added across every card to give you a total daily burn rate based on today's balances and rates.

What does the 12 month projection assume?

The projection assumes you pay only the minimum payment you entered for each card, add no new charges, and your APR does not change. If your minimum payment is too low to cover interest, the balance will grow over the year. Real credit card minimums usually adjust down as the balance falls, but this calculator holds them fixed to show the worst case discipline scenario.

Why is utilization optional?

Utilization requires you to enter your credit limit for each card. If you skip that field, the rest of the snapshot still works. Utilization above 30% can start to drag your credit score, and above 50% has a meaningful negative impact, so it is worth filling in if you can find the limits on your statements.
