Loan Calculator: True Cost

See the real interest cost. Amortization schedule, extra payment savings.

Your bank shows you one number: your monthly payment.

They hide the number that matters — the TOTAL interest you'll pay over the life of your loan. On a typical 30-year mortgage, you pay more in interest than the original home price itself.

This calculator exposes that number. Instantly.

WHAT YOUR BANK WON'T TELL YOU

$300,000 mortgage at 6.8% for 30 years?
✗ Monthly payment: $1,961
✗ What they hide: $406,000 in interest
✗ Total you actually pay: $706,000

That's 57% of every payment going straight to the bank — not your home.

Now you know.

5 LOAN TYPES COVERED

🏠 Mortgage — Home purchase or refinance
🚗 Auto Loan — Car, truck, or motorcycle
💼 Personal Loan — Debt consolidation, expenses
🎓 Student Loan — Federal or private
📊 Business Loan — Small business financing

Each loan type pre-fills typical rates so you can calculate instantly.

EXTRA PAYMENT SIMULATOR

Slide to add an extra $50, $100, or $200 per month. Watch in real-time as:

→ Your payoff date moves years earlier
→ Thousands in interest disappear
→ Your total savings update instantly

Adding just $100/month extra on a 30-year mortgage saves over $30,000 in interest and pays off 4 years early.

FULL AMORTIZATION SCHEDULE

See every single payment for the life of your loan — month by month.

Color-coded rows show you the truth:
🔴 Early payments: mostly interest
🟢 Late payments: mostly principal

Milestone badges reveal:
⚡ The exact month principal finally beats interest (it takes longer than you think)
🎯 When you're 25% paid off
🏆 When you hit the halfway mark

Annual summaries show total principal and interest paid each year.
