payment is made. I wanted to build a simple tool that helps people understand how long it will take to become debt-free and how much interest they'll pay before making financial decisions.

Why I Built This
Many online calculators are overloaded with ads or require unnecessary sign-ups.
My goal was simple:
Fast calculations
Clean interface
Mobile-friendly
No login required
Completely free
What the Calculator Does
Just enter:
💳 Credit Card Balance
📈 Annual Interest Rate (APR)
💰 Monthly Payment
The calculator instantly estimates:
✅ Monthly payment impact
✅ Time required to pay off the balance
✅ Total interest you'll pay
✅ Total repayment amount
Credit card payoff calculators help users compare repayment scenarios and understand how increasing monthly payments can reduce both payoff time and total interest.
Built With
HTML5
CSS3
Vanilla JavaScript
Responsive Design
Everything runs directly in the browser, making the experience lightweight and fast.
Why This Matters
A small increase in your monthly payment can significantly reduce the amount of interest paid over the life of your debt. That's why I wanted users to experiment with different payment amounts and immediately see the results.
Planned Features
I'm currently working on:
📊 Amortization Schedule
📅 Estimated Payoff Date
💵 Extra Monthly Payment Calculator
📄 Printable Report
🌙 Dark Mode
