Home Loan Calculator - Payment and Interest

A home loan calculator estimates the monthly cost of borrowing for a property before you request a lender's formal Loan Estimate. Enter the home price, down payment, interest rate, and term to see the principal-and-interest payment. Add property tax, homeowners insurance, HOA fees, and an estimated PMI rate when you want a broader housing budget rather than a loan-only number.

• • Compare home prices: Test several purchase prices while keeping your planned down payment and loan term consistent.
• • Compare loan terms: Contrast a 15-year and 30-year schedule to see the tradeoff between monthly payment and lifetime interest.
• • Plan cash requirements: See how a larger down payment changes the amount financed and whether the simplified PMI trigger is removed.
• • Build a housing budget: Add taxes, insurance, and HOA dues so the result is closer to a recurring monthly housing expense.

Use the result for scenario planning, not as a loan offer or affordability decision. The calculator assumes a fully amortizing fixed-rate loan and does not estimate closing costs, prepaid escrow, discount points, lender credits, or variable-rate changes.

If you already know your target payment, change one assumption at a time. Comparing the same home at two rates or terms makes the effect of each choice easier to read.

For a parallel estimate centered on escrow costs, use the mortgage calculator with taxes and insurance to compare a second housing-payment view.

The calculation separates the loan payment from recurring property costs. First, the down payment is converted to dollars, then the remaining principal is amortized across the selected number of monthly payments.

• H and D: H is home price and D is the dollar down payment; a percentage down payment is converted from H first.
• P: P is the amount borrowed after subtracting the down payment.
• r: r is the annual interest rate divided by 12 and then by 100.
• n: n is the loan term in years multiplied by 12.
• M: M is the fixed monthly principal-and-interest payment.
• PMI: PMI is estimated as P times the annual PMI rate divided by 12 when LTV is above 80%.

The Consumer Financial Protection Bureau describes the standard mortgage payment as a mathematical calculation based on the loan terms. The result here keeps full precision during the schedule and displays currency to two decimals.

Taxes and insurance are budget provisions, not interest on the loan. Total interest is based only on scheduled principal-and-interest payments, so it does not include PMI, HOA dues, taxes, insurance, or closing charges.

According to Consumer Financial Protection Bureau, lenders calculate principal and interest for most mortgages with a standard mathematical formula based on the loan terms.

If you want the same amortization idea framed specifically as an EMI, compare the home loan EMI calculator.

These terms explain why two homes with the same price can have different monthly payments and total borrowing costs.

A payment that looks affordable because it includes only principal and interest can understate the recurring cost of owning the property. Review the total monthly result and each line item separately.

This home loan calculator does not substitute APR for the interest rate in the formula because APR incorporates charges that depend on a specific loan offer. Compare official Loan Estimates when choosing between lenders.

To isolate borrowing cost from taxes and insurance, use the mortgage interest calculator for an interest-focused comparison.

Run a baseline first, then change one assumption at a time so the payment difference has a clear cause.

1. 1 Enter the home price: Use the purchase price you are comparing, not an estimate of the home's future value.
2. 2 Add the down payment: Enter dollars or switch the unit selector to percent. The calculator converts a percentage into a dollar amount.
3. 3 Set rate and term: Enter the annual fixed interest rate and loan term in years, such as 6.5% and 30 years.
4. 4 Add recurring costs: Enter annual tax, annual insurance, monthly HOA, and an estimated PMI rate if the down payment is smaller.
5. 5 Read and compare: Review total monthly payment, line-item costs, total interest, and the annual amortization schedule.

For a $400,000 home, start with $80,000 down and a 30-year term. Then test $100,000 down without changing the rate. The lower principal should reduce principal-and-interest cost and may remove the simplified PMI estimate.

When you know your income and debts but not your target price, the house affordability calculator is a better next step than guessing a home price.

A component-level estimate helps you make comparisons that a single payment number cannot show.

• • See the full monthly picture: Taxes, insurance, PMI, and HOA fees are displayed beside principal and interest instead of being hidden in one total.
• • Measure term tradeoffs: A shorter term usually raises the monthly principal-and-interest payment while reducing scheduled interest.
• • Test down-payment choices: Dollar and percentage modes show how cash invested at closing changes the loan balance and PMI estimate.
• • Plan rate sensitivity: Small rate changes can be tested quickly before you compare lender quotes or decide whether to buy points.
• • Track balance progress: The annual amortization schedule shows principal paid, interest paid, and remaining balance over time.

These benefits are strongest when you compare like-for-like scenarios. Keep taxes, insurance, and HOA assumptions unchanged when comparing terms, then update them separately when you have property-specific estimates.

Use the displayed total interest as a scheduled-loan comparison, not a promise of the final cost. Refinancing, selling, extra payments, escrow changes, and early payoff can change what you actually pay.

For a deeper balance-by-balance view, continue with the mortgage amortization calculator after comparing the headline payment here.

The result depends on loan assumptions and property costs, so treat it as a planning estimate until a lender supplies verified terms.

• • Taxes and insurance are divided evenly across 12 months here. Actual escrow payments can change after reassessment, premium renewal, or an account shortage.
• • PMI is a simplified annual-rate estimate. Conventional PMI pricing, cancellation timing, FHA insurance, VA funding fees, and other loan-program rules are not modeled.
• • The estimate excludes closing costs, prepaid items, discount points, lender credits, adjustable-rate changes, and late-payment effects.

The CFPB describes PITI as principal, interest, taxes, and insurance, and notes that a total mortgage payment can include additional costs. That is why the calculator keeps the loan payment and housing-cost components visible.

Use a lender's Loan Estimate to verify the rate, APR, mortgage insurance, escrow, cash to close, and payment schedule for a real application. The calculator is useful for comparing scenarios before that document exists.

A 20% down payment is not a universal rule for every mortgage. The CFPB says conventional borrowers may be required to pay PMI below that level, while government-backed loans can use different insurance structures.

According to the Consumer Financial Protection Bureau, PITI means principal, interest, taxes, and insurance, while a total mortgage payment can also include other costs.

According to the Consumer Financial Protection Bureau, private mortgage insurance may be required for a conventional loan when the down payment is less than 20 percent of the purchase price.

If a lender offers discount points for a lower rate, compare the upfront-cost tradeoff with the mortgage points calculator.
