How to Calculate using Mortgage Points Calculator?
One needs to follow the below steps in order to calculate the Mortgage Points benefits.
Step #1 – Calculate the amount of upfront payment which would be the percentage of loan amount and multiply the same by a number of points the borrower has chosen to pay upfront.
Step #2 – Now, enter the loan amount first, which is the principal amount:
Step #3 – Multiply the principal by the rate of interest applicable for without points.
Step #4 – Now, we need to compound the same by rate until the loan period.
Step #5 – We now need to discount the above result obtained in step 3 by the following:
Step #6 – After entering the above formula in excel, we shall obtain periodically installments.
Step #7 – Repeat steps from 2 to step 5 but this time with interest rate applicable with points.

Mortgage Points Calculator Examples
Example #1
Karry had purchased the house with a Mortgage loan. The loan amount was $110,000 and it was taken for 25 years. Further, the rate applicable was 8.75%. Karry complained about the higher rate being charged as currently, the bank was offering fresh home loans at 8.50%.
The Manager of the bank told her that even she can be shifted to a rate of 8.25% if she opts for Mortgage points. On inquiry, she came to that purchasing 1 mortgage point will equal 1% of loan amount and she has to purchase 4 mortgage points.
You are required to calculate Mortgage points to benefit out of this.
Solution:
 We need to calculate the EMI amount with points and without points interest rate.
 The number of installments is 25 years but since it is monthly outgo hence the number of payments required to be paid is 12*25 which is 300 equally installments
 And lastly, the rate of interest is 8.75% fixed which shall be calculated monthly which is 8.75%/12 which is 0.73% and 8.25%/12 which is 0.69%.

Upfront Payment Calculation
$110,000 x 1% x 4 = $4,400
Now we shall use the below formula to calculate the EMI amount.

Without Points:
= [110,000*0.73%*(1+0.73%)^300]/[(1+0.73%)^300–1]
= 904.36

With Points:
= [110,000*0.69%*(1+0.69%)^300]/[(1+0.69%)^300–1]
= 867.30

Benefits per month: EMI without points – EMI with points
= 904.36 – 867.30
= 37.06
Therefore, 34.81 * 300 which shall equal to $8,354.29 less $4,400 which is net benefit of $3,954.29
Example #2
Mr. KJ has a current loan outstanding for $80,000 which he initially financed at 7.89% and 10 years are yet left for the loan to be fully paid. Now Bank has recently launched for their existing borrowers to purchase mortgage points and reduced their interest rate and henceforth monthly installment. The scheme detail is below:
Mr. KJ decides to purchase 4 mortgage points. Based on the given information you are required to determine whether it was worth deal?
Solution:
We need to calculate the EMI amount with points and without points interest rate. The number of remaining installments is 10 years but since it is monthly outgo hence the number of payments required to be paid is 12*10 which is 120 equally installments and lastly, the rate of interest is 7.89% fixed which shall be calculated monthly which is 7.89%/12 which is 0.66% and 7.26%/12 which is 0.61%.

Upfront Payment Calculation
$80,000 x 1% x 4 = $3,200
Now we shall use the below formula to calculate the EMI amount.

Without Points:
= [80,000*0.66%*(1+0.66%)^120 ]/[(1+0.66%)^120–1]
= 965.98

With Points:
= [800,000*0.61%*(1+0.61%)^120]/[(1+0.61%)^120–1]
= 939.62

Benefits per month: EMI without points – EMI with points
= 965.98 – 939.62
= 26.35
Therefore, 26.35 x 120 which shall equal $3,162.45 less $3,200 which is a net loss of $37.55.
Hence, it doesn’t affect if he buys 4 mortgage points and in effect, he suffers loss and hence he should avoid buying 4 mortgage points.
Conclusion
If the borrower can afford to purchase the mortgage points, then he needs to figure out if the deal is worth it or else, he can take the help of a financial advisor. There is a general rule of thumb: the longer the loan the borrower keeps, the mortgage points will become more attractive. Also, one needs to calculate the payback period of the upfront amount paid while making the decision.
