What Is the Formula for Monthly Mortgage Payments?
Understanding the standard amortization equation helps demystify how bank loan officers calculate monthly home payments. The core formula for monthly mortgage (Principal and Interest) is:
M = P × [ r(1 + r)^n ] ÷ [ (1 + r)^n − 1 ]
Where:
- M: Total Monthly Payment (P&I)
- P: Principal Loan Amount (Home Price − Down Payment)
- r: Monthly Interest Rate (Annual Interest Rate ÷ 12 ÷ 100)
- n: Total Number of Monthly Payments (Loan Term in Years × 12)
Example Calculation: $300,000 Home Purchase
- Home Price: $300,000 | Down Payment (20%): $60,000 | Principal (P): $240,000
- Interest Rate: 6.5% per annum (r = 0.065 ÷ 12 = 0.0054167)
- Loan Tenure: 30 Years (n = 360 months)
- Monthly Payment (M): $1,516.98 per month
- Total Interest Paid over 30 Years: $306,114.30
What Are the 6 Types of Mortgages?
When applying for a mortgage loan, buyers choose between several primary loan structures based on their credit score, down payment, and financial goals:
| Mortgage Type | Key Characteristics | Best Used For |
|---|---|---|
| 1. Conventional Fixed-Rate Mortgage | Interest rate and monthly payment remain constant for 15 or 30 years. Not insured by government. | Buyers with solid credit (620+) and 3%–20% down payment. Using a conventional loan calculator helps estimate these standard payments. |
| 2. Adjustable-Rate Mortgage (ARM) | Fixed introductory rate for 5, 7, or 10 years, after which the rate adjusts periodically. | Buyers planning to sell or refinance before the introductory fixed rate expires. |
| 3. FHA Loan (Federal Housing Admin) | Government-backed loan allowing down payments as low as 3.5% with flexible credit rules. | First-time homebuyers with lower credit scores (580+). |
| 4. VA Loan (Veterans Affairs) | 0% down payment loan with competitive rates for active-duty military, veterans, and surviving spouses. | Qualified US military members and eligible veterans. |
| 5. USDA Loan (US Dept of Agriculture) | 0% down payment government-backed loan for rural and suburban homebuyers. | Low-to-moderate income buyers purchasing in designated rural areas. |
| 6. Jumbo Loan | Non-conforming mortgage exceeding FHFA county loan limits. Requires strict credit and large down payment. | Luxury home buyers financing high-value real estate. |
How Is Mortgage Interest Calculated?
Mortgage interest is calculated on a monthly compounding cycle based on the remaining principal balance. Early in a 30-year amortization schedule, the majority of your monthly payment goes toward interest, while a smaller portion reduces principal. As the principal drops, the monthly interest charge decreases, accelerating principal reduction in later years.
Monthly Interest Charge = Remaining Loan Balance × (Annual Interest Rate ÷ 12)

Frequently Asked Questions
To calculate a mortgage, subtract your down payment from the home purchase price to find the loan principal. Then, apply the standard amortization formula using your annual interest rate, loan term (e.g. 15 or 30 years), and compounding frequency to calculate your monthly principal and interest payment.
The 6 primary types of mortgages are: (1) Conventional Fixed-Rate Mortgages, (2) Adjustable-Rate Mortgages (ARM), (3) FHA Loans, (4) VA Loans, (5) USDA Loans, and (6) Jumbo Loans.
Mortgage interest is calculated monthly based on your remaining loan balance. Multiply your remaining principal balance by your annual interest rate divided by 12 (Monthly Interest = Remaining Principal × [Annual Interest Rate / 12]). Early in the loan, a larger portion of your monthly payment goes toward interest.
For a ₹20 Lakh (₹2,000,000) mortgage loan at an average interest rate of 8.5% per annum for a 20-year tenure (240 months), the estimated monthly EMI is approximately ₹17,356 per month. Total interest payable over 20 years is ₹21.65 Lakhs.
The standard monthly mortgage payment formula is: M = P [ r(1 + r)^n ] / [ (1 + r)^n - 1 ], where M is monthly payment, P is principal loan amount, r is monthly interest rate (annual rate / 12), and n is total number of monthly payments (years × 12).
To calculate a mortgage loan: (1) Determine the home purchase price and subtract your down payment. (2) Identify the annual interest rate offered by the lender. (3) Choose your loan term (e.g., 15, 20, or 30 years). (4) Enter these numbers into the CalculatorsDaily Mortgage Calculator for instant monthly payment and total interest figures.
