Use this Mortgage Calculator with Taxes and Insurance to estimate a more complete monthly housing payment, including principal, interest, property taxes, homeowners insurance, and optional HOA dues and PMI.
Important: This calculator provides a planning estimate. Your lender’s Loan Estimate and Closing Disclosure should be used for official mortgage payment and closing-cost figures.
Mortgage Payment Calculation Method
First calculate the mortgage amount:
Loan amount = home price − down payment
If you enter a loan amount directly, the calculator uses that amount instead.
For a fixed-rate mortgage, the monthly principal-and-interest payment is:
M = P × [r(1 + r)n] ÷ [(1 + r)n − 1]
Where:
- M = monthly principal and interest payment
- P = loan amount
- r = monthly interest rate
- n = total number of monthly payments
Monthly interest rate = annual interest rate ÷ 12 ÷ 100
Taxes, Insurance, HOA and PMI
Annual property taxes and homeowners insurance are converted to monthly amounts:
Monthly property tax = annual property tax ÷ 12
Monthly homeowners insurance = annual insurance ÷ 12
The estimated total monthly housing payment is:
Total monthly payment = principal and interest + property tax + insurance + HOA + PMI
This is similar to a PITI calculation, with optional HOA dues and mortgage insurance added when applicable.
Example
Suppose you are buying a $350,000 home with:
- 20% down payment
- 6.5% fixed interest rate
- 30-year mortgage
- $3,600 annual property tax
- $1,200 annual homeowners insurance
- $150 monthly HOA dues
- $75 monthly PMI
The down payment is:
$350,000 × 20% = $70,000
The mortgage amount is:
$350,000 − $70,000 = $280,000
The estimated monthly principal and interest payment is:
≈ $1,769.79
Monthly property tax:
$3,600 ÷ 12 = $300
Monthly homeowners insurance:
$1,200 ÷ 12 = $100
Total estimated monthly payment:
$1,769.79 + $300 + $100 + $150 + $75 = $2,394.79
If estimated closing costs are 3% of the purchase price:
Closing costs = $350,000 × 3% = $10,500
Using the calculator’s simplified method:
Estimated cash to close = $70,000 + $10,500 = $80,500
Important Notes
- Enter the mortgage interest rate rather than APR when estimating the scheduled principal-and-interest payment.
- Property taxes and homeowners insurance can change, so the total monthly payment may change even when principal and interest remain fixed.
- PMI may apply to some conventional mortgages with less than 20% down and increases the cost of the loan.
- HOA dues are generally separate housing expenses and may also change over time.
- The calculator’s cash-to-close figure is simplified. Actual cash to close may include prepaids, initial escrow deposits, lender or seller credits, deposits already paid, and other adjustments.
- Closing-cost percentages are estimates; actual lender and settlement charges vary considerably.
- The calculation is intended primarily for standard fixed-rate mortgages. Adjustable-rate, interest-only, balloon, FHA, VA, USDA, and other loan structures may require different calculations.
- Use your official Loan Estimate and Closing Disclosure when comparing or finalizing a mortgage.
How to Use the Mortgage Calculator with Taxes and Insurance
Start with figures from the same date and use the same units throughout. Enter home price, down payment, rate, term, property tax, insurance, mortgage insurance, and association dues. Use realistic assumptions rather than a best-case guess, then calculate a baseline. Save or note that result before changing one input at a time. This makes it easier to see which assumption has the greatest effect and prevents several simultaneous changes from hiding the reason the result moved.
The calculator reports estimated total monthly housing payment and component breakdown. Treat those outputs as a scenario, not a promise or formal quote. Recheck any figure that comes from a statement, contract, tax notice, lender disclosure, or service provider. Small differences in timing, rounding, fees, or definitions can become meaningful when a balance is large or a time period is long.
How to Interpret the Results
The main purpose is to combine principal and interest with major recurring ownership charges. Compare at least three cases: a conservative case, a reasonable working case, and a more favorable case. Keep the time period and measurement basis consistent so the comparison remains useful. If the result drives an important decision, check both the recurring amount and the cumulative total; a manageable monthly figure can still carry a substantial long-term cost.
Look for sensitivity, not only a single answer. Change the rate, term, payment, price, or contribution slightly and calculate again. If a small input change causes a large output change, that assumption deserves extra verification. Also remember that taxes, premiums, assessments, utilities, maintenance, and escrow adjustments can change. This tool is for education and preliminary planning; it is not individualized financial, tax, legal, lending, or investment advice.
Scenario Checklist
- Use current balances, rates, prices, and payment dates whenever possible.
- Keep percentages in percentage fields and money values in the selected currency.
- Compare like with like: the same time horizon, payment frequency, and cost basis.
- Include known fees and recurring charges when the calculator provides those fields.
- Run a downside case so the plan is not dependent on one optimistic assumption.
- Confirm important figures with the relevant provider or qualified professional before acting.

Frequently Asked Questions
What does the Mortgage Calculator with Taxes and Insurance calculate?
It uses home price, down payment, rate, term, property tax, insurance, mortgage insurance, and association dues to estimate estimated total monthly housing payment and component breakdown. The result follows the formulas and assumptions described on this page. It is most useful for exploring a clearly defined scenario and comparing alternatives on the same basis.
How accurate is the Mortgage Calculator with Taxes and Insurance?
The arithmetic is based on the values entered, so input quality determines usefulness. Real-world results can differ because taxes, premiums, assessments, utilities, maintenance, and escrow adjustments can change. Use exact figures where available and rerun the calculation whenever a rate, balance, price, payment, or time period changes.
Which inputs have the biggest effect?
The most influential inputs are usually the starting amount, rate or percentage, recurring cash flow, and time horizon. Their importance varies by calculation. Test one input at a time and watch both the immediate result and the cumulative total.
Can I use this calculator to compare two options?
Yes. Calculate each option separately with the same date, units, frequency, and horizon. Record the recurring result, total result, and any amount excluded from the model. A fair comparison also considers flexibility, risk, liquidity, and fees that cannot be reduced to one number.
Does the result include every tax, fee, or charge?
Only items represented by the available inputs are included. The calculator cannot automatically know account-specific fees, local taxes, provider rules, changing rates, penalties, or contract terms. Review the notes above and verify exclusions before relying on the estimate.
How should I use the result in a financial decision?
Use it as a starting point for questions and scenario testing. Compare conservative and favorable cases, confirm source figures, and consider whether the result remains workable if conditions worsen. For regulated products, taxes, or major commitments, compare the estimate with official documents and professional guidance.
