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.

Singapore Mortgage Standards & Regulatory Limits

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

MSR 30% for residential; TDSR 55% of income for all debt.

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.

Reviewed 2026-09-11 · Yes. You can use funds from your CPF Ordinary Account (OA) to pay down the principal, cover the initial 20% deposit, and pay the monthly installments, significantly reducing your out-of-pocket cash flow. However, when you eventually sell the property, you must refund the CPF principal used plus accrued interest back into your CPF account.

Singapore Mortgage Guide 2026: HDB, TDSR, and ABSD Rules

The Singaporean mortgage market is highly regulated by the MAS to prevent property bubbles. Borrowing is heavily dictated by property type (public HDB flats vs. private condominiums) and stringent debt-servicing limits. The market is also heavily taxed for foreigners and investors via the ABSD. This guide outlines the 2026 lending landscape.

How Much Can You Borrow in Singapore? ▼

Your borrowing capacity is determined by three strict macroprudential rules: LTV limits, TDSR, and MSR (for HDBs only).

Loan-to-Value (LTV) Limits

Bank Loan (Private Property or HDB): Maximum 75% LTV. You must provide a 25% down payment. Crucially, at least 5% of the purchase price must be paid in hard cash; the remaining 20% can come from your CPF (Central Provident Fund) Ordinary Account.

HDB Concessionary Loan (HDB only)Maximum 80% LTV. You need a 20% down payment, all of which can be paid using CPF.
Total Debt Servicing Ratio (TDSR) ▼

Applies to all property purchases. Your total monthly debt obligations (mortgage, car loans, credit cards) cannot exceed 55% of your gross monthly income.

To calculate TDSR, banks must use a medium-term stress test rate. In 2026, the stress rate is typically 4.0% for residential properties.

Mortgage Servicing Ratio (MSR)

Applies only to HDB flats and Executive Condominiums (ECs). The monthly mortgage payment alone cannot exceed 30% of your gross monthly income. This is a much tighter constraint than TDSR and severely limits borrowing for public housing.

Use the affordability calculator to test your income against the 55% TDSR and 30% MSR limits.

Singapore Mortgage Types

Fixed Rate: The rate is locked for a short period (usually 2, 3, or 5 years). Provides stability. Break costs apply if you refinance or sell during the lock-in period.

Floating Rate (SORA-pegged): Tied to the Singapore Overnight Rate Average (SORA) — usually a 1-month or 3-month compounded SORA plus a bank margin. Highly transparent.

Board RateA variable rate determined internally by the bank. Less transparent than SORA.

HDB Concessionary Rate: Fixed at 0.1% above the CPF Ordinary Account interest rate (currently 2.60%). It is exceptionally stable but occasionally slightly higher than competitive bank rates.

Current Singapore Mortgage Rates (2026) ▼

Following MAS policy adjustments, typical 2026 rates are:

2-year or 3-year Fixed3.10% to 3.40%
3-month Compounded SORA + Margin3.20% to 3.60%

HDB Loan: 2.60%

*Rates are illustrative averages as of September 2026.*

Closing Costs and Taxes (Buyer's Stamp Duty) ▼

Singapore uses taxes aggressively to control foreign investment and multiple property ownership.

Buyer's Stamp Duty (BSD)

Progressive tax applied to all buyers. Approx. 1% on first $180k, 2% on next $180k, 3% on next $640k, 4% on next $500k, and up to 6% for properties over $3 million.

Additional Buyer's Stamp Duty (ABSD)
Singapore Citizens0% on 1st property, 20% on 2nd, 30% on 3rd.
Permanent Residents (PR)5% on 1st property, 30% on 2nd.

Foreigners: A massive 60% flat rate on any property purchase (subject to Free Trade Agreement exemptions, e.g., US citizens pay the same as SG citizens).

Other Buyer Costs:

Legal Fees$1,500 to $3,000 SGD.
Valuation Fee$200 to $500 SGD.

Use the budget calculator to estimate your massive ABSD liability and total cash/CPF required.

The Singapore Mortgage Process

1. Secure the Deposit. You need 5% in hard cash and 20% in CPF for a bank loan. Check your CPF OA balance.
2. Obtain In-Principle Approval (IPA). Valid for 30 days. Ensures you meet TDSR/MSR limits.
3. Option to Purchase (OTP). You pay a 1% cash booking fee to the seller to secure the OTP. You typically have 14 to 21 days to exercise it.
4. Exercise the OTP. You sign the OTP and pay the remaining 4% in cash (to complete the 5% cash requirement).
5. Pay Stamp Duties. BSD and ABSD must be paid within 14 days of exercising the OTP (can be reimbursed from CPF later, but usually requires cash upfront).
6. Completion. Takes 10 to 12 weeks. Your lawyer draws down the mortgage and CPF funds to pay the seller.
Can I use CPF to pay my monthly mortgage? ▼

Yes, eligible buyers can withdraw funds from their Central Provident Fund Ordinary Account (CPF OA) to service both their initial down payment (up to 20% for bank loans, or the full 20% for HDB concessionary loans) and recurring monthly mortgage payments. However, usage is subject to the Valuation Limit (VL) and Housing Withdrawal Limit (HWL) set by the CPF Board. Furthermore, when you eventually sell the property, you are required by law to refund all CPF principal withdrawn plus the 2.5% per annum compound accrued interest back into your CPF OA account.
