The short version

The payment people quote is often just principal and interest. The payment you make each month usually holds more than that. It has up to five parts:

  • Principal pays down what you owe.
  • Interest is the cost of borrowing, figured each month on the balance you still owe.
  • Property taxes are set by the county. Most loans collect them a little each month into an escrow account and pay the bill when it is due.
  • Homeowners insurance is required while you have the loan, and it is usually paid from escrow too.
  • Mortgage insurance applies to conventional loans with less than 20% down and to FHA and USDA loans. VA loans have none.

On a fixed-rate loan, principal and interest stay the same for the life of the loan. Taxes and insurance can change from year to year, so the escrow part of your payment can rise or fall even when your rate never moves.

HOA dues are paid to the association, not in the mortgage payment, but they count when we figure what you qualify for.

In Southwest Colorado, taxes and insurance differ a lot from home to home: from about $600 a year in taxes and $800 in insurance to about $3,000 of each. That alone can move a payment by a few hundred dollars a month, so we use the home's actual tax bill and a real insurance quote.

The picture

  • Interest about 73%
    The cost of borrowing, figured on what you still owe
  • Principal about 11%
    Pays down the loan
  • Property taxes about 6%
    Set by the county, held in escrow
  • Homeowners insurance about 5%
    Required by the lender, held in escrow
  • Mortgage insurance about 4%
    Until enough is paid down

Worked example

A $300,000 home

Example
  • 5% down, conventional
  • 30-year fixed
  • Example rate 6.75%
  • Taxes $1,500 a year
  • Insurance $1,400 a year
Monthly payment, first month, by part
InterestThe cost of borrowing, figured on what you still owe$1,603
PrincipalPays down the loan$245
Property taxesSet by the county, held in escrow$125
Homeowners insuranceRequired by the lender, held in escrow$117
Mortgage insuranceUntil enough is paid down$95
Monthly payment, first month$2,185

Of the first payment, about $1,603 is interest. Each month a little more goes to principal; on this loan principal passes interest after about 20 years. Once mortgage insurance comes off, the payment drops by $95.

Why most of an early payment is interest

Each month, interest is figured on the balance you still owe: the balance times the rate, divided by 12. Early on the balance is at its largest, so interest takes most of the payment. As the balance falls, interest shrinks and principal grows, while the total for principal and interest stays the same.

Extra principal shortens this. See paying extra on your mortgage.

How escrow works

An escrow account holds the money for property taxes and homeowners insurance. Part of each payment goes in, and the servicer pays the bills when they are due. Most loans collect taxes and insurance this way; some conventional loans can skip escrow with a larger down payment.

Once a year the servicer reviews the account. Federal rules let it keep a cushion of up to two months of payments, refund a surplus of $50 or more, and spread a shortage over the coming year. That review is why a payment can change in the first year. See your first year of owning.

What the payment does not include

HOA dues, utilities, upkeep and repairs are paid on their own. If the home is in a mapped flood zone, flood insurance is required and is usually paid from escrow as well. Before you settle on a budget, add the costs a lender leaves out.
