The core of the monthly principal and interest (P&I) payment calculation uses the standard amortization formula:
Where:
M = Monthly Payment (P&I)
P = Principal Loan Amount
r = Monthly Interest Rate (Annual Rate / 1200)
n = Total Number of Payments (Loan Term in Years × 12)
Formula Sources: Investopedia – Amortization, CFPB – Loan Basics
Variables Explained
- Loan Amount: The principal balance borrowed from the lender.
- Annual Interest Rate: The nominal yearly rate (e.g., 6.5%).
- Loan Term (Years): The duration over which the loan is paid back (e.g., 30 years).
- Annual Property Tax: The estimated yearly property tax, which is typically escrowed and paid monthly.

What is the California Mortgage Calculator?
A mortgage calculator for California is a crucial planning tool designed to give prospective and current homeowners a detailed breakdown of their likely monthly housing costs. While the core P&I calculation is universal, including state-specific inputs like estimated property tax rates and insurance costs for high-value California homes provides a much more accurate budget picture.
The primary components calculated are PITI: Principal, Interest, Taxes, and Insurance. Additionally, this tool includes a field for Homeowners Association (HOA) dues, which are a common monthly expense in many California communities and significantly impact affordability. Understanding your total monthly obligation is key to preventing financial strain after closing on a property.
How to Calculate a Monthly Payment (Example)
- Identify Variables: Assume a Loan Amount ($P$) of $400,000, an Annual Rate ($R$) of 6.0%, and a Term ($T$) of 30 years.
- Calculate Monthly Rate (r): Convert the annual rate to a monthly decimal: $r = 0.06 / 12 = 0.005$.
- Calculate Total Payments (n): Convert the term to months: $n = 30 \times 12 = 360$.
- Solve the Formula: Substitute these values into the P&I formula to find the monthly principal and interest payment ($M$).
- Add Escrow/HOA: Sum the calculated $M$ with the monthly property tax (Annual Tax / 12), monthly home insurance (Annual Insurance / 12), and any monthly HOA dues.
- Review Total: The final result is the total estimated monthly housing payment.
Frequently Asked Questions (FAQ)
Property taxes and insurance are usually collected by the lender monthly and held in an escrow account. The calculator takes your annual tax input and divides it by 12, adding that amount to your P&I payment to find the total escrowed payment.
Do California mortgages have special rules?The mortgage calculation itself is standard, but California housing costs are typically higher. Buyers should account for high property values, potential Mello-Roos taxes (not included here, but important), and elevated insurance premiums due to fire risk, making a detailed calculator like this essential.
What is the difference between P&I and PITI?P&I stands for Principal and Interest—the amount that goes directly toward paying off the loan and its interest. PITI includes the P&I plus Property Taxes (T) and Homeowner’s Insurance (I). PITI is the most accurate figure for your actual monthly out-of-pocket payment to the lender.
Can I solve for the Loan Amount I can afford?This version is primarily designed to calculate the payment based on a fixed loan amount. To solve for affordability, you would need to use a separate loan affordability calculator, which reverses the formula based on your maximum desired monthly payment.
