Buy-To-Let Mortgage and Profit Calculator

This calculator compares two kinds of Buy-To-Let mortgage and shows profit figures when the property is rented out.

The deposit required for a buy-to-let mortgage is usually higher than a standard mortgage, typically 25% although can be as high as 40%.

Interest rates and fees are generally higher.

The first mortgage plan shown is a normal annuity type plan, where an amount is paid off the mortgage as well as interest.

The mortgage interest is calculated on the outstanding mortgage balance so more is paid off the mortgage amount as the payments progress.

The other is an Interest only plan, where the interest only is paid over the duration of the mortgage, the mortgage amount becoming due at the end of the period.

The profit figures are displayed in three sections as below:

  1. The first is where the figures for the mortgage period only are shown, excluding the deposit and any final payment,
  2. The second mortgage plan includes the final payment in the calculations, this is relevant to the interest only plan,
  3. The third mortgage plan includes the initial deposit and final payment (if relevant) to show the total mortgage cost

A breakeven figure is also displayed, this is the costs shown as a monthly amount.

Calculations can be saved to a table for comparison by clicking the "Add to table" button (table appears below the schedule comparison).

The table appears the first time the button is clicked.
