The Free Google Sheets Mortgage Calculator has a single sheet, containing the input with their sample values and the resulting mortgage per month.

2. Add the Required Inputs such as Sale Price, Interest Rate Per Annum, Number of Years, and Payments per Year 

The required inputs for the sheet to work are the following:

  • Sale Price - total price of the property
  • Interest rate per annum - interest rate set
  • Number of years - duration of the mortgage
  • Payments per year - number of payments to be made per annum; for monthly payments it is equal to 12

For our example, here are the inputs:

  • Sale Price - $300,000.00
  • Interest rate per annum - 4.00%
  • Number of years - 20 years
  • Payments per year - 12

The base monthly mortgage will be automatically calculated as you input the values.

Often additional costs are added to the resulting monthly payment such as additional payment per month (that goes straight to the principal), mortgage insurance, and escrow. Add them in the additional fields.
