I am assuming you want to know your monthly repayment amount.
The formula for calculating mortgage rate in Excel is PMT. It throws out a negative number indicating the negative cashflow but you can multiply it by -1 to make it look decent. So, here's recipe to cook a mortgage (and I'll demonstrate it with an example in a bit)
Ingredients required:
1. Monthly Interest Rate (annual interest rate divided by 12)
2. Number of Months (number of years times 12)
3. Loan amount
Method:
Take the PMT pan and put the 3 ingredients in it in the order above. Then add some seasoning of negativity by multiply it by -1.
Monthly Repayment Amount = PMT(Monthly_Interest_Rate,Number_of_Months,Loan_Amount)*-1
Example:
Let's say your interest rate is 4.8% per year, which works out to be 0.4% per month. Let's assume that your repayment period is 25 years, that is 300 months. And let's say your loan amount is a million dollars. The formula will look something like this:
Monthly Mortgage Amount = PMT(0.4%,300,1000000)*-1
Monthly Repayment Amount = $ 5,729.97
Hope that helps.
