| Year | Principal Paid | Interest Paid | Balance Remaining |

Principal
The portion of your payment that reduces the actual loan balance. This increases over time as your balance decreases.
Interest
The cost your lender charges for lending you money. Interest is highest in early years and decreases as balance drops.
Property Tax
Annual local/state tax on your home value, typically 0.5%–2.5% of home value, paid monthly into an escrow account.
Homeowner’s Insurance
Protects your home from damage, theft, and liability. Most lenders require it. Average cost: $800–$2,000/year.

Understanding the Mortgage Formula
Your monthly principal and interest payment is calculated using the standard mortgage amortization formula:
- M = Monthly payment (principal + interest)
- P = Loan amount (home price minus down payment)
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Total number of monthly payments (years × 12)
For example, on a $320,000 loan at 7% annual interest for 30 years: r = 0.07/12 = 0.005833, n = 360. Monthly P&I = $2,129. Adding taxes, insurance, and HOA brings the total to roughly $2,600–$2,900 depending on your location.
How Much Down Payment Do You Need?
The standard down payment recommendation in the US is 20% of the home price. Here’s why that number matters:
- Less than 20% down: Most lenders require PMI (Private Mortgage Insurance), which typically adds $50–$200+ per month to your payment. PMI protects the lender, not you, and is not included in this calculator.
- 20% or more: You avoid PMI entirely, get better interest rates, and have more equity from day one.
- FHA Loans: Allow as little as 3.5% down with a credit score of 580+. Great for first-time buyers.
- VA Loans: Eligible veterans can buy with 0% down and no PMI. Check eligibility at VA.gov.

Fixed Rate vs. Adjustable Rate Mortgage (ARM)
When applying for a home loan in the US, you’ll typically choose between two main types:
Fixed-Rate Mortgage
Your interest rate stays the same for the entire loan term (10, 15, 20, or 30 years). Monthly payment is predictable and never changes. Best for long-term homeowners in a low-rate environment.
Adjustable-Rate Mortgage (ARM)
Rate is fixed for an initial period (5, 7, or 10 years), then adjusts annually based on market index. Initially lower rate, but carries risk if rates rise. Best for short-term homeowners.
Tips to Lower Your Monthly Mortgage Payment
- Make a larger down payment — reduces your loan amount and eliminates PMI
- Improve your credit score — a score of 760+ qualifies you for the best rates (often 0.5%–1% lower)
- Choose a longer loan term — 30 years vs 15 years means lower monthly payments (but more total interest)
- Shop multiple lenders — rates can vary significantly; get at least 3 quotes
- Buy discount points — pay upfront to permanently lower your interest rate
- Refinance when rates drop — if rates fall 1%+ below your current rate, refinancing often makes sense
