What This Mortgage Calculator Does

This mortgage calculator, built for Számológép.com, estimates your monthly home loan payment and shows the full breakdown of what that payment is made of. Instead of only giving you the raw principal-and-interest figure, it adds property taxes, home insurance, PMI, HOA fees, and other recurring homeownership costs so you can see the realistic amount you would pay out of pocket every month. Enter the home price, down payment, loan term, interest rate, and start date, then press Calculate. The tool instantly generates a monthly payment summary, a donut chart showing how your payment is split, a full loan summary with total interest paid over the life of the loan, and a year-by-year (or month-by-month) amortization schedule with a balance/interest/payment trend chart. Whether you are a first-time buyer comparing loan offers or a homeowner exploring refinancing, this calculator helps you understand the true cost of a mortgage before you sign anything.

  4. Interest Rate — enter your fixed annual interest rate (APR).
  5. Start Date — pick the month and year your first payment is due.
  6. Taxes & Costs — optionally include property tax, home insurance, PMI, HOA fees, and other costs for a complete monthly figure.

Worked Example

A $400,000 home with a 20% down payment ($80,000), a 30-year term, and a 6.579% interest rate results in a loan amount of $320,000. The principal & interest portion comes to roughly $2,039 a month. Adding property tax (1.2% annually), $1,500/year home insurance, and $4,000/year in other costs brings the total out-of-pocket monthly payment to around $2,897, with roughly $414,000 paid in interest over the full 30-year term.

Frequently Asked Questions

How is the monthly mortgage payment calculated?

The calculator uses the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the loan amount, r is the monthly interest rate, and n is the total number of monthly payments. Taxes, insurance, PMI, HOA, and other costs are then added on top of this principal-and-interest figure.

What is PMI and when does it apply?

Private Mortgage Insurance (PMI) is usually required when your down payment is less than 20% of the home price. It protects the lender if you default on the loan and is typically removed automatically once your loan-to-value ratio drops to 80% or below.

What's the difference between the annual and monthly amortization schedule?

The annual schedule groups your payments by year, showing total interest, principal, and remaining balance for each year of the loan. The monthly schedule breaks the same information down payment by payment, which is useful for tracking exact payoff progress.

Does a larger down payment always save money?

Generally yes — a larger down payment reduces your loan amount, lowers your monthly payment, cuts total interest paid, and can help you avoid PMI. However, it also ties up more cash upfront, so it's worth weighing against your other financial goals.

Is this calculator accurate for my exact loan?

This tool provides a close estimate based on the numbers you enter. Actual mortgage offers may include lender fees, rate adjustments, closing costs, or region-specific tax rules not captured here, so always confirm final figures with your lender.
