Santander Mortgage Calculator – Accurate Loan Estimates

Use this Santander mortgage calculator tool to estimate your monthly mortgage payments quickly and easily.

How to Use the Santander Mortgage Calculator

This mortgage calculator helps you estimate your monthly mortgage payments based on various input parameters such as loan amount, annual interest rate, loan term, and property value.


  • Enter the loan amount you wish to borrow.
  • Enter the annual interest rate in percentage (e.g., for 5% enter 5).
  • Enter the loan term in years.
  • Enter the property value.
  • Click on the “Calculate” button to see your estimated monthly payment.

How It Works:

The calculator uses the following formula to compute the monthly mortgage payment based on the inputs provided:

[ M = P frac{r(1+r)^n}{(1+r)^n – 1} ]


  • M: Monthly payment
  • P: Loan amount
  • r: Monthly interest rate (annual interest rate divided by 12)
  • n: Total number of payments (loan term in years multiplied by 12)


  • The calculator provides an estimate and may not reflect the exact monthly payment you will need to make as other factors such as taxes, insurance, and fees may apply.
  • Interest rates may vary over the loan term, so this estimate might not reflect future changes in interest rates.
