Mortgage estimate

A mortgage payment depends on the loan amount, interest rate and term. Depending on the property and location, taxes, insurance, mortgage insurance, association charges and fees may also affect the overall cost. Add the costs that apply to your situation to compare scenarios.

This calculator provides an estimate from the values entered and the selected country assumptions. It does not assess a complete mortgage application or replace a lender's offer. Inputs are sent over HTTPS for calculation and are not saved to an account or calculation database.

Who Benefits Most

First-time homebuyers benefit from seeing their true total monthly housing commitment—encompassing principal, interest, tax escrows, hazard insurance, and private mortgage insurance—before making an offer on a home. Existing homeowners evaluating a refinance can accurately test whether monthly interest savings offset appraisal, origination, and title fees to establish their true breakeven date. International expatriates, cross-border professionals, and relocating families can contrast borrowing limits, mandatory deposit thresholds, and repayment mechanics across different legal jurisdictions without switching software or deciphering unfamiliar terminology.

Country-specific details

The calculators cover country-specific details such as US PMI rules, Australian Lenders Mortgage Insurance (LMI), Canadian mortgage default insurance, and German annuity structures (Annuitätendarlehen with Tilgung and Zinsbindung). Inputs are sent to our application over HTTPS to calculate results, but are not saved to an account or calculation database. Shareable links may include the values you entered.

A Practical Walk-Through of Our Financial Tool Suites

Making sound property and borrowing decisions requires looking beyond an isolated loan payment. Our platform arranges complementary financial tools into three specialized suites, allowing you to examine every dimension of your personal balance sheet.

1. Housing and Mortgage Suite

The Home Affordability Calculator estimates a price from income, debts and country assumptions. The Mortgage Calculator estimates payments from the loan amount, rate, term and costs you enter. You can also compare extra payments, refinancing costs, or rent and buy scenarios using your own assumptions.

2. Income, Tax, and Budgeting Suite

The Salary Calculator estimates take-home pay using the selected country and the details entered. The Budget Calculator helps organize income and expenses. Both can help you explore a budget, but neither decides whether a lender will approve an application.

3. Debt Elimination and Wealth Accumulation Suite

The Debt Consolidation and Loan Calculators compare payments and interest using the values you provide. The Compound Interest Calculator illustrates how contributions and assumed returns affect a future balance; returns are not guaranteed.

How to Use This Mortgage Calculator

Begin by entering your agreed Home Price, which represents the gross purchase valuation stated on your real estate purchase agreement. Next, enter your cash Down Payment (or deposit). The calculator subtracts this down payment from the property price to determine your net base loan principal, displaying your Loan-to-Value (LTV) percentage immediately. If your down payment is below conventional thresholds (such as 20% in the United States, Australia, or Canada), the system automatically incorporates statutory mortgage default insurance into your monthly projections.

Enter the annual interest rate and loan term from the offer you want to assess. A shorter term usually has higher regular payments and may reduce interest over the life of the loan. Add estimates for property taxes, insurance, mortgage insurance and HOA dues to see their effect on monthly housing costs.

Calculation Methodology & Statutory Standards

For a fixed-rate loan with regular monthly payments, the principal and interest estimate uses the standard amortization equation:

M = P × [ r(1 + r)n ] / [ (1 + r)n − 1 ]

In this formula, M is the monthly principal and interest payment, P is the loan principal, r is the monthly interest rate, and n is the number of monthly payments.

Each payment first covers interest on the outstanding balance; the remainder reduces principal. Taxes, insurance and other costs are shown from the values entered and country assumptions. Actual lender calculations, insurance rules and escrow amounts may differ; confirm them with your lender and relevant authority.

Frequently Asked Questions About Mortgage Financing

What is the practical difference between a mortgage interest rate and the APR?

The interest rate is the baseline annual cost of borrowing expressed as a percentage of your outstanding principal balance. The Annual Percentage Rate (APR) reflects the broader cost of financing, bundling the base interest rate together with origination points, discount points, processing fees, underwriting charges, and essential settlement expenses. Under Regulation Z of the Truth in Lending Act enforced by the Consumer Financial Protection Bureau (CFPB), lenders must disclose the APR so borrowers can make an apples-to-apples comparison across competing mortgage offers that feature differing upfront fee structures.

When and how can Private Mortgage Insurance (PMI) be cancelled?

Under the federal Homeowners Protection Act of 1998, you have the legal right to submit a written request to cancel PMI once your regular payments bring the principal loan balance down to 80% of the property's original value, provided your payment history is satisfactory. In addition, mortgage loan servicers are required by law to cancel PMI automatically once your amortization schedule reaches 78% of the original value, without requiring borrower intervention. Loans backed by the Federal Housing Administration (FHA) follow different statutory rules: borrowers who put down less than 10% must maintain Mortgage Insurance Premiums (MIP) for the entire duration of the loan.

How do additional principal curtailments reduce total loan cost and payoff duration?

Because mortgage interest is calculated monthly against the remaining principal balance, applying extra funds directly toward the principal lowers every subsequent monthly interest charge. For example, adding an extra $200 each month to a $400,000 30-year fixed loan at 6.75% eliminates more than five years of scheduled payments and prevents over $85,000 in interest charges from accruing. Conforming residential mortgages carry no statutory prepayment penalties, meaning borrowers can pay down principal at any cadence without penalty.

How does a fixed-rate mortgage compare against an adjustable-rate mortgage (ARM)?

A fixed-rate mortgage guarantees that your principal and interest payment remains identical over the entire loan life, shielding household budgets from macroeconomic rate volatility. An adjustable-rate mortgage (ARM) or tracker loan provides an initial discounted interest rate for a fixed period (such as 3, 5, or 7 years), after which the rate adjusts periodically according to a benchmark index (such as SOFR in the United States or the Bank of England base rate in the United Kingdom) plus a lender margin. Borrowers who plan to relocate or refinance before the initial fixed period expires can save significant interest with an ARM, but they accept the risk of higher future payments if benchmark rates rise.

Australia Mortgage Standards & Regulatory Limits

Mortgage underwriting in Australia follows domestic statutory frameworks governing maximum loan-to-value (LTV) limits, minimum cash deposits, and mandatory interest rate stress tests. This calculator automatically incorporates Australia standards into its assumptions so that your results reflect realistic underwriting requirements rather than generic estimates.

Serviceability assessed with a rate buffer. Lenders mortgage insurance above ~80% LTV.

Calculation Methodology & Proof

Mortgage (PITI + schedule)

The loan is amortized as above. Housing cost adds tax, insurance, HOA, and PMI. UK-style splits keep an interest-only balloon.

PITI = M + tax/12 + insurance/12 + HOA + PMI. IO payment = IO balance × r. Balloon = IO balance at term.
  1. Loan amount = price − down payment. LTV = loan / price.
  2. If an interest-only amount is set, only the remainder amortizes.
  3. PMI (when enabled) is charged while scheduled LTV is above the threshold (default 80%).
  4. Total cost sums interest, fees, and the recurring housing add-ons over the payoff period.

Important Caveats & Planning Assumptions

  • Tax and insurance are estimates; escrow analysis will differ.
  • PMI cancellation rules vary by product and country.

Frequently Asked Questions

Expert answers to common questions

What is included in the monthly total?

Principal and interest, plus estimated property tax, home insurance, HOA, and PMI when LTV is above the threshold. That PITI figure is what lenders use for affordability.

When does PMI drop off?

This calculator removes PMI once the scheduled balance reaches 80% of the original purchase price. Servicers may also need an appraisal; rules vary by country and loan type.

How does a UK split mortgage work here?

Set an interest-only amount. That slice is charged interest only and remains as a balloon; the rest amortizes over the term.

Australia Mortgage Guide 2026: APRA Buffers, LMI, and Serviceability

Buying a home in Australia involves navigating strict serviceability tests, Lenders Mortgage Insurance (LMI) for low deposits, and state-based stamp duties. Regulated by the Australian Prudential Regulation Authority (APRA) and the Australian Securities and Investments Commission (ASIC), the Australian market is predominantly variable-rate or short-term fixed (1 to 3 years). This guide breaks down the rules, rates, and costs for 2026.

How Much Can You Borrow in Australia? ▼

Your borrowing power is strictly regulated by the Australian Prudential Regulation Authority (APRA) to ensure you can withstand interest rate shocks.

The 3.0% APRA Serviceability Buffer ▼

Lenders must assess your ability to repay the loan at a rate that is at least 3.0 percentage points higher than your actual loan rate. If your home loan rate is 6.00%, the bank will test your income and expenses as if the rate were 9.00%. This significantly reduces maximum borrowing capacity compared to pre-2021 levels.

Household Expenditure Measure (HEM) ▼

Banks use the HEM to estimate your minimum living expenses based on your family size and income, disregarding your declared expenses if they are lower than the HEM baseline.

Use the Australian affordability calculator to estimate your borrowing capacity under current APRA buffers.

Down Payments and Lenders Mortgage Insurance (LMI) ▼
20% DepositThe gold standard. Avoids LMI and secures the best interest rates.

Less than 20% Deposit: Triggers Lenders Mortgage Insurance (LMI). LMI is a one-off insurance premium that protects the lender, not you. It can cost anywhere from $5,000 to $30,000 depending on your loan size and LVR (Loan-to-Value Ratio), and is usually capitalized (added) into your loan balance.

Minimum Deposit: Generally 5%, though some lenders require 10%. Certain government schemes for first home buyers allow 2% to 5% deposits without paying LMI.

Australian Mortgage Types ▼

Variable Rate: The interest rate moves with the Reserve Bank of Australia (RBA) cash rate and lender discretion. Typically includes features like 100% offset accounts and unlimited extra repayments.

Fixed Rate: Locked for 1 to 5 years. Breaking a fixed rate early incurs heavy break costs. Offset accounts are rare on fixed loans, and extra repayments are capped (e.g., $10,000 per year).

Principal and Interest (P&I): Standard amortization where you pay off both the loan amount and interest.

Interest Only (IO): You only pay the interest. Common for investment properties for tax purposes, but residential owner-occupiers pay a premium rate for IO loans.

Current Australian Mortgage Rates (2026) ▼

Following the RBA's cash rate holds in 2026, typical owner-occupier P&I rates are:

Variable Rate (LVR < 80%)5.80% to 6.20%

1-year Fixed: 6.00% to 6.30%

3-year Fixed5.75% to 6.10%

*Rates are illustrative averages as of September 2026.*

Closing Costs and Stamp Duty ▼

Stamp Duty (Transfer Duty) is the largest upfront cost for Australian buyers. It varies wildly by state and territory.

Typical Costs on a $800,000 Home
Stamp Duty (NSW)~$31,000
Stamp Duty (VIC)~$43,000
Stamp Duty (QLD)~$21,000
LMI (if 10% deposit)~$15,000 to $18,000
Conveyancing/Legal$1,500 to $2,500
Loan Application/Settlement Fees$300 to $800

First Home Owner Grants (FHOG) and stamp duty concessions are available in most states for newly built homes or properties under specific price thresholds.

Worked Example: Purchasing an $800,000 AUD Home in NSW ▼

Consider an Australian buyer purchasing an $800,000 property in New South Wales comparing a 20% deposit ($160,000) against a 10% deposit ($80,000):

Expense Item20% Deposit Tier (80% LVR)10% Deposit Tier (90% LVR)
Base Loan Amount$640,000$720,000
Lenders Mortgage Insurance (LMI)$0 (Exempt)$16,800 (Capitalized)
Total Borrowed Balance$640,000$736,800
NSW Transfer Stamp Duty$31,090$31,090
Legal Conveyancing & Registration$2,200$2,200
Total Upfront Cash Required$193,290$113,290

Putting down 20% avoids $16,800 in LMI charges, reduces total loan interest by over $95,000 across a 30-year term, and unlocks top-tier interest rate discounts.

The Australian Mortgage Process ▼
1. Save your deposit (Genuine Savings). Banks want to see a 3- to 6-month history of consistent saving.
2. Get Pre-Approval (Conditional Approval). Valid for 90 days, it gives you a firm budget.
3. House Hunting and Purchasing. Buying at auction requires an immediate 10% deposit and no cooling-off period. Private treaty purchases usually have a subject to finance clause.
4. Formal Approval. The lender conducts a valuation of the property and issues unconditional approval.
5. Settlement. Typically 30 to 90 days after signing the contract. Your conveyancer handles the transfer of funds and title.
Frequently Asked Questions About Australian Mortgages ▼

What is an Offset Account?

An offset account is a standard transaction account linked directly to your variable-rate mortgage. Every dollar in this account reduces the loan balance on which interest is calculated daily. For example, if you owe $600,000 and hold $50,000 in your offset account, interest is charged only on $550,000, creating tax-free compound interest savings while retaining full liquidity.

Do I need to pay Lenders Mortgage Insurance (LMI)?

Yes, if your cash deposit is less than 20% of the property's purchase price (an LVR above 80%). LMI protects the lender against loss if you default. However, full LMI waivers are offered by many Australian banks for accredited professionals (such as doctors, medical specialists, lawyers, and chartered accountants) up to 90% or 95% LVR, or through the federal government's Home Guarantee Scheme.

Can I make extra repayments on an Australian home loan?

Variable-rate home loans allow unlimited extra repayments without penalty, and funds can be retrieved through a redraw facility. Fixed-rate loans, however, typically cap extra repayments at $10,000 per year, and breaking a fixed rate early triggers break costs based on wholesale interest rate differentials.
