What this calculator does
This calculator estimates monthly mortgage principal and interest for a fixed-rate home loan. It also lets you add annual taxes and insurance or similar housing costs to get a fuller monthly budget view.
How to use it
Select USD or GBP, enter the property price, down payment, interest rate, and term. Add annual taxes and insurance if you want a closer estimate of all-in monthly housing cost. The results update instantly as you compare scenarios.
Example usage
You can compare a 20% down payment versus 10% down payment on the same property and immediately see the effect on the loan amount, monthly payment, and total interest. This is helpful when planning affordability and cash reserves before buying.
