How to Use the Mortgage Calculator
- Enter the expected home price.
- Enter the down payment in dollars or as a percentage.
- Use an illustrative interest rate and choose the loan term.
- Add available estimates for property taxes, homeowners insurance, HOA dues and mortgage insurance when applicable.
- Adjust one input at a time to compare purchase scenarios.
The home price minus the down payment generally determines the starting loan amount. A larger down payment may lower the amount borrowed, but it can also change mortgage-insurance requirements, pricing and the amount of cash needed at closing.
Understanding the Result
Principal and interest
The loan payment based on the amount borrowed, interest rate and term.
Total housing payment
May also include property taxes, homeowners insurance, mortgage insurance and HOA dues. Not every result includes every cost.
Cash needed at closing
Separate from the monthly payment. It may include the down payment, closing costs and prepaid expenses, minus eligible credits.
Loan assumptions
The rate, term and expenses entered are planning inputs. They are not a current offer or approval.
Worked Example
Illustrative example only—not a rate quote.
For a $600,000 home with 20% down:
- Down payment: $120,000
- Estimated loan amount: $480,000
- Illustrative rate and term: 6.25% for 30 years
- Estimated principal and interest: approximately $2,955 per month
Property taxes, homeowners insurance and any HOA dues would be added to estimate the full monthly housing cost.
Why a San Luis Obispo County Estimate Can Change
Two similarly priced homes can have different total payments. Property tax assessments, insurance premiums, HOA dues, property type and loan program can all affect the final numbers. The rate available to a borrower can also depend on credit, down payment, occupancy, loan amount and other factors.
