Mortgage calculator

Portugal Mortgage Calculator.

Estimate monthly debt service before you make an offer. Use the payment output in your DSCR, break-even rent, and cash-on-cash model.

How to use it

Start with the loan, then test the property.

Monthly payment is not the return

Use the payment to calculate DSCR and cash flow. A bank approval does not prove that a rental property is a good investment.

Stress the rate

Run the same deal at rates one point higher. If the DSCR breaks, negotiate the price or use less debt.

Connect to tax

After debt, test rental income tax and IMI before you trust cash-on-cash return.
