How the payment is built

One formula for the loan, then the monthly add-ons.

The worked example: a starter townhouseLoan$306,000$340,000 less 10%P and I$1,9346.5%, 360 monthsPlus$709tax, insurance, PMI, HOAA month$2,643all inThe worked example: a starter townhouseLoan$306,000$340,000 less 10%P and I$1,9346.5%, 360 monthsPlus$709tax, insurance, PMI, HOAA month$2,643all in
The amortization formula gives principal and interest; the other pieces are added by the month.

Principal and interest

A fixed-rate loan is paid in equal monthly amounts that cover each month’s interest and pay down the balance. The formula uses the monthly rate, the yearly rate divided by 12, and the number of months.

What sits on top

Most lenders collect property tax and homeowners insurance with the payment through an escrow account. With less than 20% down on a conventional loan, private mortgage insurance is added until the balance falls to 80% of the original value. HOA dues are paid separately but belong in the same budget.
