Los Angeles Mortgage Calculator

By SoFi Editors | Updated October 7, 2025

A mortgage calculator is an indispensable tool for anyone considering buying a home, whether they’re a first-timer or a veteran homeowner. It can help you estimate monthly payments, the total interest you’ll pay, and the overall cost of a given mortgage, enabling you to make informed decisions about your financial future. By inputting key details like the home price, down payment, loan term, and interest rate, you can get a clear picture of what you can expect and how different scenarios might impact your budget. The Los Angeles mortgage loan calculator is not just invaluable, it’s also free, fast, and easy to use. Read on to get started.

Key Points

•  The Los Angeles mortgage calculator can help you estimate monthly payments, total interest, and overall mortgage costs when you input data about a mortgage you’re considering.

•  Down payment assistance programs are often available to help first-time homebuyers and others manage the initial costs of buying a home.

•  A larger down payment can lead to better interest rates and lower monthly payments, and a 20% down payment can eliminate the need for private mortgage insurance (PMI).

•  The loan term you choose, typically 15 or 30 years, significantly affects monthly payments and total interest paid, with shorter terms offering lower interest costs but higher monthly commitments.

•  Different ways to estimate the affordability of a mortgage include applying the 28/36 rule, using a home mortgage affordability calculator, and going through the mortgage preapproval process with a lender.

Calculator Definitions

• Home price: The home price is the purchase price you have agreed on with the home seller. It will probably not be the same as either the listing price or your initial offer.

• Down payment: The down payment is the amount that you will pay upfront in a lump sum and is often expressed as a percentage of the purchase price of your home. Most buyers put down between 3% and 20% — the latter eliminates the need for private mortgage interest (PMI). If this seems like a heavy lift, down payment assistance programs may be available to help with the cost.

• Loan term: The loan term is the length of time you’ll have to repay the mortgage. The most common are 30 years and 15 years. The shorter term generally results in higher monthly payments but lower total interest paid over the life of the loan, while the longer offers lower monthly payments but higher total interest.

• Interest rate: The interest rate is the cost of borrowing money, typically represented as a percentage of the loan amount.

• Annual property tax: This is the tax levied on land and the buildings on it by local government, typically expressed as a percentage of the assessed value of the property. The annual property tax rate in Los Angeles is typically around 0.70% of the home’s assessed value as of late 2025. Rates vary, so to find your current tax obligation, search online for your ZIP code or city and “effective property tax rate.”

• Total monthly payment: The total monthly payment is the amount that you will repay your lender every month. It covers the principal on your loan, the interest, and (if you enter your property tax rate in the Los Angeles mortgage calculator) property tax.

• Total interest paid: The total interest paid is the sum of all the interest you will pay over the life of your home loan. This figure can vary significantly based on the interest rate, loan term, and down payment.

• Total loan cost: The total loan cost is the complete amount you will repay for the loan, including both principal and total interest.
