How to use this calculator

Loan structures explained

Most loan calculations fall into one of three patterns: regular amortized payments, a single deferred payoff at maturity, or a present-value calculation that works backward from a known future amount.

  • Use the amortized mode for mortgages, auto loans, student loans, and other installment loans that are paid back over time.
  • Use the deferred-payment mode when the balance compounds until one lump-sum amount is due at maturity.
  • Use the bond mode to estimate how much money is effectively received at the start when the maturity value is already known.

Formula / method

Formula / method

This page supports multiple loan structures, so the method changes by mode. Amortized loans spread repayment across regular periods, deferred loans grow to a maturity value, and bond-style mode works backward from present value and future value relationships.

  • Amortized mode uses periodic-payment math for equal installments over time.
  • Deferred mode uses future-value growth until maturity.
  • Bond mode uses present-value and coupon-style cash-flow logic.

FAQ

Common Loan questions

What is the difference between amortized and deferred-payment loans?

An amortized loan spreads repayment across recurring payments, while a deferred-payment loan allows the balance to grow until one lump-sum payoff is due at maturity.

Why do compounding frequency and repayment frequency matter?

Compounding controls how often interest is added to the balance, while repayment frequency controls how often money is paid back. Changing either one can shift payment size, total interest, and the final amount due.

What is the bond section useful for?

It is useful when you already know the maturity value of a loan or zero-coupon bond and want to estimate the present value, or how much is effectively received when the loan starts.
