Advanced Loan Calculator

Calculate loan payments, total interest, and payoff time with support for different loan types, payment frequencies, and extra payments for faster debt clearance.

Formulas Used

  • Monthly Payment (Amortized Loan):
  • PMT = P × [r(1 + r)^n] / [(1 + r)^n − 1]
  • Interest per Period:
  • Interest = Remaining Balance × r
  • Principal Payment:
  • Principal = Payment − Interest
  • Total Interest:
  • Total Interest = Total Payments − Loan Amount
  • Compound Growth (Deferred Loan):
  • FV = P × (1 + r)^n

Loan Insights

  • - Calculates loan payments, interest, and payoff duration.
  • - Supports amortized, interest-only, deferred, and bond loans.
  • Loan Types:
  • - Amortized: Fixed payments with principal + interest.

  • - Deferred: Full payment at end with accumulated interest.
  • - Bond: Periodic interest, principal paid at maturity.
  • Payment Frequency:
  • - Monthly, weekly, or yearly payments supported.
  • - More frequent payments reduce total interest.
  • Extra Payments:
  • - Reduces principal faster.
  • - Significantly lowers total interest paid.
  • Interest Impact:
  • - Higher interest → higher total repayment.
  • - Small rate changes greatly affect long-term cost.
  • Amortization:
  • - Early payments mostly go toward interest.
  • - Later payments reduce principal faster.
  • Smart Tips:
  • - Pay extra whenever possible to save interest.
  • - Choose shorter loan term if affordable.
  • - Compare different loan scenarios before deciding.
  • Notes:
  • - Longer loans reduce monthly payments but increase total cost.
  • - Extra payments can drastically reduce payoff time.
  • - Always consider total repayment, not just monthly payment.
