Kaip apskaičiuoti Mortgage

Kas yra Mortgage?

A mortgage calculator computes monthly repayments for a home loan based on the loan amount, interest rate, and term. In a repayment mortgage, each payment covers interest plus a portion of the capital, so the balance decreases over time and reaches zero at the end of the term.

Formulė

Monthly payment M = P × r(1+r)^n / ((1+r)^n − 1)

M: Total repaid − P — Total repaid − P
P: loan amount — loan amount
