What Goes Into a Monthly Mortgage Payment?
Five pieces, and most buyers only plan for the first one:
- Principal and interest. The loan itself, paid back over 15, 20 or 30 years. On a fixed-rate loan this part never changes.
- Property tax. In California it's based on your purchase price, not the seller's old value.
- Homeowners insurance. Your lender will require it, and the cost varies a lot from one home to the next.
- HOA dues. Only if the home is in a homeowners association. Condos and many newer neighborhoods have them.
- Mortgage insurance. Usually added when you put down less than 20% on a conventional loan.
Tax and insurance are often collected with your payment and held in an impound account, which pays those bills for you when they come due. That's why the calculator rolls them into one monthly number.
How Does Your Down Payment Change the Payment?
Every dollar you put down is a dollar you don't borrow. A bigger down payment lowers the loan amount, which lowers principal and interest. Cross 20% and mortgage insurance usually drops off too.
That doesn't mean you should empty your savings to get there. Keep money for closing costs, moving, and the first repairs every home needs. Sometimes a smaller down payment and a cushion in the bank is the better plan. Try both in the calculator and see the gap.
What Is Mortgage Insurance, and When Does It Go Away?
Mortgage insurance protects the lender, not you, if a loan with a small down payment goes unpaid. You pay for it, usually as a monthly charge. The calculator uses a yearly percent of the loan as an estimate. Your real cost depends on your credit, your down payment and the loan type.
- Conventional loans. You can usually ask to remove it once you owe 80% of the home's original value, and it ends on its own at 78%.
- FHA loans. They have their own mortgage insurance with different rules for how long it lasts.
- VA loans. No monthly mortgage insurance. Most VA buyers pay a one-time funding fee instead.
What's Different About Buying in Sacramento?
California property tax starts at a 1% base under Prop 13, plus local bonds and assessments. The calculator starts at about 1.25% of the price as an estimate. For the real number on a specific area, use the Sacramento property tax calculator, and add any Mello-Roos on newer homes.
Plan for the supplemental tax bill.
After you buy, the county sends a catch-up bill for the difference between the seller's old value and your price. It often arrives 6 months or more after closing, and it comes to you, not your loan servicer. Set the money aside from the month you close.

Frequently Asked Questions
How is a monthly mortgage payment calculated?
Principal and interest come from a standard formula that spreads the loan over the number of monthly payments at your interest rate. Early payments are mostly interest, later ones mostly principal, and the total stays the same on a fixed-rate loan. Then add one twelfth of your yearly property tax and homeowners insurance, any monthly HOA dues, and mortgage insurance if your loan has it.
Do I need 20% down to buy a home?
No. Many loan programs allow less. On a conventional loan, putting down less than 20% usually means paying mortgage insurance until you build enough equity. FHA loans have their own mortgage insurance rules, and VA loans don't charge monthly mortgage insurance. Ask which programs fit you before you pick a number.
Why is the interest rate in this calculator only an example?
Because a real rate depends on you and the loan. Credit, down payment, loan type, the property and the day you lock all change it. The calculator runs the math on whatever rate you type. For a real quote, talk with a licensed loan originator, and compare more than one.
Does my mortgage payment cover the supplemental property tax bill?
Not automatically. In California the county sends a supplemental bill after you buy, often 6 months or more after closing, and it goes to you, not your loan servicer. Set money aside for it from the month you close.
