Karl's Tip

A 20% down payment can help you avoid Private Mortgage Insurance (PMI), which typically costs between 0.5% and 1% of your loan amount annually.

Consider making bi-weekly payments instead of monthly to pay off your mortgage faster and save on interest.

How to Use Karl’s Mortgage Calculator

Easily work out your mortgage details with these simple steps:

  • Start by entering the purchase price of the home, for example $300,000, in the Purchase Price field. Then move on to the down payment, where you can add either the total amount, like $60,000, or a percentage such as 20 percent, and the other value will update automatically.
  • Next, fill in your loan details by entering the interest rate, for instance 4.5 percent, and choosing a loan term that suits you, whether it is 10, 15, 20, or 30 years. After that, include your yearly costs by adding property taxes, such as $3,000, and homeowners insurance, for example $1,200.
  • If your property has any HOA fees, you can enter the monthly amount, or simply leave it at zero if it does not apply. Once everything is set, click Calculate to instantly see your monthly payment, a full loan summary, and a detailed amortization schedule.
  • You can also explore the amortization breakdown by opening the collapsible section, where you will find a clear yearly view of how much goes toward principal, interest, and the remaining balance.
