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.

South Africa Mortgage Standards & Regulatory Limits

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

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.

South Africa Mortgage Guide 2026: Prime-Linked Rates, Bonds, and Transfer Duties

The South African mortgage market (commonly referred to as "Home Loans" or "Bonds") is characterized by a heavy reliance on variable interest rates pegged to the SARB Prime lending rate. The market is highly accessible for first-time buyers, with 100% LTV loans common, provided the borrower passes stringent National Credit Act (NCA) affordability tests. This guide outlines the 2026 lending landscape.

How Much Can You Borrow in South Africa? ▼

Lending in South Africa is governed less by hard LTV caps and more by strict affordability assessments under the NCA to prevent reckless lending.

Loan-to-Value (LTV) Limits

First-Time Buyers: Maximum 100% LTV is widely available. Banks frequently finance the entire purchase price. First-time buyers with strong credit can sometimes get a 105% LTV loan to cover closing costs (transfer duties and bond registration fees), though this attracts a higher interest rate.

Standard Buyers / Repeat BuyersMaximum 90% to 100% LTV. A 10% deposit is often recommended to secure a better interest rate.

Foreigners / Non-Residents: Maximum 50% LTV. Non-residents must bring at least 50% of the purchase price into South Africa from an offshore account.

Debt-to-Income (DTI) Limit (Affordability Assessment)

Banks strictly adhere to the NCA guidelines. Your mortgage payment generally cannot exceed 30% of your gross monthly income.

More importantly, banks conduct a Net Surplus calculation: Gross Income minus Statutory Deductions (Tax, UIF) minus Living Expenses minus Existing Debt Obligations. If the net surplus cannot cover the new mortgage payment (stress-tested against future rate hikes), the loan is declined.

Use the affordability calculator to determine your maximum mortgage based on the strict 30% DTI limit and net surplus rules.

South African Mortgage Types ▼

Variable Rate (Prime-Linked): The overwhelming majority (over 90%) of South African home loans are variable. The interest rate is quoted as Prime plus or minus a margin (e.g., Prime - 0.50% or Prime + 1.00%). When the SARB changes the repo rate, the Prime rate changes immediately, altering your monthly installment.

Fixed Rate: You can usually fix your rate for 1 to 5 years. However, in South Africa, fixed rates are typically offered at a premium (higher than the current variable rate) to price in the bank's future risk. Because of this premium, most buyers stick to variable rates.

Current South African Mortgage Rates (2026) ▼

Following SARB rate adjustments, the Prime Lending Rate is the benchmark.

Prime Lending Rate (2026 Average)11.25% to 11.75%
Good Credit / High DepositPrime - 0.50% to Prime - 1.00% (e.g., 10.75%)
100% LTV / Borderline CreditPrime + 0.50% to Prime + 1.50% (e.g., 12.75%)

*Rates are illustrative averages as of September 2026.*

Closing Costs and Taxes ▼

Closing costs in South Africa are substantial, primarily driven by the progressive Transfer Duty and high legal fees (conveyancing).

Transfer Duty (SARS)

Properties under R1,100,000 are completely exempt from Transfer Duty.

R1,100,001 to R1,512,500: 3% of the value above R1.1m.

R1,512,501 to R2,117,500: R12,375 + 6% of the value above R1.512m.

The scale progresses up to 13% for properties over R12.1 million.

Conveyancing Fees (Legal Fees)

You must pay two separate sets of attorneys:

1. Transfer Attorney: Appointed by the seller, but paid for by the buyer. Registers the transfer of ownership at the Deeds Office. Fees are tariff-based (e.g., ~R30,000 for a R2m property).
2. Bond Attorney: Appointed by the bank, paid for by the buyer. Registers the bank's mortgage bond over the property. Fees are tariff-based (e.g., ~R28,000 for a R2m bond).

Total Cash Needed: Budget exactly 4% to 8% of the property price for closing costs (unless the property is under R1.1m, which drastically reduces the cash requirement). Use the budget calculator for a complete estimate.

The South African Mortgage Process ▼
1. Get Pre-Approval. Use a Bond Originator (e.g., Ooba, BetterBond). They apply to multiple banks (Standard Bank, Absa, FNB, Nedbank) simultaneously on your behalf for free.
2. Sign the Offer to Purchase (OTP). A legally binding contract. Always include a "Subject to Bond Approval" suspensive clause, giving you 14 to 21 days to secure financing.
3. Bank Valuation. The bank assesses the property to ensure it holds enough value to cover the bond.
4. Bond Approval (Grant Quotation). The bank issues the final offer detailing the interest rate and conditions.
5. Sign Legal Documents. You meet with both the Transfer Attorney and the Bond Attorney to sign the respective documentation and pay their pro-forma invoices (including Transfer Duty).
6. Registration at the Deeds Office. Lodgement and registration take about 10 to 15 working days. On the day of registration, the bank pays the seller, and you take ownership.
What is an Access Bond facility? ▼

A highly popular feature. It allows you to pay extra money into your home loan to reduce the capital balance (and thus the interest charged), while retaining the right to withdraw those extra funds later if you need cash. It effectively acts as a high-interest savings account.

Are there early repayment penalties in South Africa? ▼

Under Section 125 of the National Credit Act (NCA), borrowers who intend to pay off and cancel their mortgage bond early (for example, upon the sale of the home or refinancing to another credit provider) must serve their mortgage lender with 90 days of written cancellation notice. If this statutory 90-day notice is omitted or waived by the borrower to expedite Deeds Office cancellation, the lending bank is legally entitled to charge an early termination penalty interest fee equivalent to the shortfall of the 90-day period.
