When you avail a home loan, you borrow an amount or principal and repay it with interest. What is the interest rate on a home loan? It is the amount you are charged for borrowing from a lender, expressed as a fraction of the principal. Therefore, how much interest on home loan is to be paid by you directly depends on this value.
An interest rate change of even 0.5% can make a huge difference to your EMIs because home loan amounts are large. So, knowing how to calculate home loan interest rate is important as is learning how to reduce home loan interest rate to make repayment more affordable.
Below is a short guide on how home loan interest is calculated in India.
You cannot compute the home loan interest rate yourself, but you can be informed about the factors that affect the interest rate. These are 3 factors that determine the home loan interest rate offered to you.
You can know how much interest on a home loan is charged to you by calculating the total cost of the loan and subtracting the principal from that.
The total cost of the loan (principal + interest) is governed by the formula,
Total loan cost = P x R x N/ (1-(1+R)-N)
Where,
P = Principal or loan amount
R = Monthly interest rate in decimal form
N = Number of months
You can calculate home loan interest in two ways:
Assume a home loan of Rs.20 lakh taken for 20 years at a 10% rate.
Here,
P = 20,00,000
R = (10/12)%
N = 240
Hence,
Total loan cost = (20,00,000 x 0.0833 x 240)/ (1-(1+0.0833)-240)
= ~Rs.46,30,832
Therefore,
Interest = Total loan cost - Principal
= Rs.46,30,832 - Rs.20,00,000
= ~Rs.26,30,832
You can use the home loan EMI calculator to compute your interest, as it offers not just the EMI value, but the total interest and total amount payable as well. To use it, fix a value for the loan amount, set the tenor, and know what the current interest rate is.
