Every day you wait, interest compounds on your full balance. InterestKilled calculates your exact daily interest and turns it into a simple daily to-do — pay the interest today so it never compounds tomorrow.
The result? Your monthly payment goes 100% toward principal, you pay off debt months or years faster, and you save thousands in interest charges.
Banks calculate interest on your balance every single day, but they only let you pay once a month. That means for 30 days, yesterday's interest earns interest on top of interest. This is called compound interest, and it's the #1 reason people stay trapped in debt.

InterestKilled uses a simple but powerful strategy: pay just today's interest every day. Here's exactly how it works, step by step.
Enter each debt account — credit cards, car loans, mortgages, student loans. Include your current balance, APR, and minimum monthly payment. That's all we need.
Supports all debt types with specialized tracking for each. Credit card utilization, loan terms, and amortization schedules are all accounted for.
Using the standard banking formula, we calculate the exact interest accruing on each account every 24 hours:
Each morning, your dashboard shows today's transfer amount for each account. Make that small payment to cover just today's interest — typically just a few dollars per account.
Log your payment with one click. The system tracks your streak and updates your balance in real time.
Because you've already paid each day's interest throughout the month, your full monthly payment now goes entirely to reducing your principal balance.
No more watching 67% of your payment vanish into interest. Every dollar of your monthly payment works for YOU.
With principal decreasing faster, next month's daily interest is even lower. It's a positive spiral — the opposite of compound interest working against you.
Track your progress with detailed reports showing exactly how much interest you've killed and how many months you've shaved off your payoff date.
