What is the formula for calculating a 30 year mortgage?
Multiply the number of years in your loan term by 12 (the number of months in a year) to get the number of total payments for your loan. For example, a 30-year fixed mortgage would have 360 payments (30x12=360).
How do you calculate principal and interest payments?
Divide your interest rate by the number of payments you'll make in the year (interest rates are expressed annually). So, for example, if you're making monthly payments, divide by 12. 2. Multiply it by the balance of your loan, which for the first payment, will be your whole principal amount.
What is the formula for mortgage interest calculation?
To find the total amount of interest you'll pay during your mortgage, multiply your monthly payment amount by the total number of monthly payments you expect to make.

|30-year fixed||15-year fixed|
|Total Interest Paid||$107,736||$39,997|
The mathematical formula for calculating EMIs is: EMI = [P x R x (1+R)^N]/[(1+R)^N-1], where P stands for the loan amount or principal, R is the interest rate per month [if the interest rate per annum is 11%, then the rate of interest will be 11/(12 x 100)], and N is the number of monthly instalments.
=PMT(rate, nper, pv, [fv], [type]) The PMT function uses the following arguments: Rate (required argument) – The interest rate of the loan. Nper (required argument) – Total number of payments for the loan taken.
The PMT function calculates the required payment for an annuity based on fixed periodic payments and a constant interest rate. An annuity is a series of equal cash flows, spaced equally in time. A mortgage is an The NPER function returns the number of periods for loan or investment.
A 30-year fixed-rate mortgage is basically a home loan that gives you 30 years to pay back the money you borrowed at an interest rate that won't change. The rate for a 30-year mortgage is typically . 5–. 75% higher than the rate for a 15-year mortgage.

How do you Calculate Simple Interest? Simple Interest is calculated using the following formula: SI = P × R × T, where P = Principal, R = Rate of Interest, and T = Time period. Here, the rate is given in percentage (r%) is written as r/100.
Use the PMT function to calculate monthly mortgage payments on a house.
The formula for how to calculate loan payments on an interest loan is simpler. i is the periodic interest rate. To calculate i, divide the nominal annual interest rate as a percentage by 100. Divide that figure by the number of payment periods in a year.
Formula for PV in Excel
NPER = Number of payment periods. PMT = Amount paid each period (if omitted—it's assumed to be 0 and FV must be included)
