How is EMI calculated in the home loan and car loan calculators? +
EMI is calculated using the standard reducing balance method: EMI = P × r × (1+r)^n / ((1+r)^n – 1), where P is the principal loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly instalments. This is the universally accepted formula used by banks and lenders worldwide.
What is a reverse mortgage and who should use that calculator? +
A reverse mortgage is a loan where senior citizens (typically aged 60+) can mortgage their home to a bank and receive regular monthly payments without selling the property. The loan is repaid when the borrower passes away or vacates the property. The Reverse Mortgage Calculator helps senior homeowners estimate how much monthly income they can receive based on their home’s value, their age, and the prevailing interest rate.
