Home Equity Calculator
See exactly how much equity you have in your home — from appreciation and principal repaid, with a 10-year growth projection
How Your Equity Was Built
Access Bond Facility
Your access bond facility (R 340 000) is the difference between your original registered bond and current balance. You can draw from this at your bond rate without re-applying. Useful as deposit for a second property.

How to Use This Calculator
Enter your current property value (you can use recent comparable sales or a property valuation), your original purchase price, original bond amount, and current bond balance (from your latest bank statement).
The calculator shows your current equity position, how that equity was built (appreciation vs principal repayment), your loan-to-value (LTV) ratio, and your available access bond facility.
Switch to the Equity Growth tab to see a projected 10-year view of how your equity will grow based on expected property appreciation and ongoing bond repayments.
The Home Equity Formula
Home equity is simply the difference between your property's market value and what you owe:
Your equity comes from two sources:
- Appreciation: Current value − Original purchase price (market growth)
- Principal repaid: Original bond amount − Current balance (your payments)
The loan-to-value (LTV) ratio tells you how much of your property is still financed:
Worked Example
Lerato bought a home in Sandton 5 years ago for R1,600,000 with a bond of R1,440,000 (10% deposit). Her current bond balance is R1,100,000.
Recent comparable sales suggest her property is now worth R2,200,000.
Her equity: R2,200,000 − R1,100,000 = R1,100,000 (50% of property value).
How it was built: R600,000 from appreciation (R2.2M − R1.6M) and R340,000 from principal repaid (R1.44M − R1.1M). Her LTV is 50%.
Lerato's access bond facility is R1,440,000 − R1,100,000 = R340,000 available to draw at her bond rate of 10.25%, which she could use as a deposit on an investment property.
Frequently Asked Questions
What is home equity and why does it matter?
Home equity is the portion of your property that you truly own -- the difference between its market value and your outstanding bond balance. It represents your net wealth tied up in the property.
Equity matters because it's a form of forced savings. Every bond payment you make reduces your balance, and property appreciation grows your equity further. You can access this equity through an access bond facility for renovations, investments, or as a deposit on a second property.
How fast does property appreciate in South Africa?
South African residential property has historically appreciated at approximately 7% per year nominally (around 3% in real terms after inflation). However, this varies significantly by location, property type, and economic conditions.
Popular suburbs in Cape Town and Johannesburg have seen above-average growth, while some areas have stagnated. Factors that boost appreciation include proximity to good schools, transport links, and low crime rates. Use this calculator's growth projections as a guide, not a guarantee.
What is an access bond and how does it relate to equity?
An access bond is a home loan feature that allows you to re-borrow money you've already paid off without applying for a new loan. Your access facility equals your original registered bond amount minus your current balance.
This is different from total equity. Your access facility is limited to the original bond registration amount, not your property's current value. To access equity above the original bond amount, you'd need to apply for a further advance or re-register a larger bond.
How do I find out my property's current market value?
Several methods to estimate your South African property's value:
- Online valuations: Property24, Private Property, and Lightstone offer free automated valuations
- Recent sales: Check what similar properties in your area have sold for recently
- Estate agent CMA: Ask a local agent for a free comparative market analysis
- Professional valuation: A sworn valuer provides an official valuation (R3,000--R5,000)
- Municipal valuation: Check your rates notice, though municipal values often lag market values
Can I use my home equity to buy a second property?
Yes, this is one of the most common uses of home equity in South Africa. You can draw from your access bond facility and use those funds as a deposit on a second property. This avoids having to save a large cash deposit.
However, remember that drawing from your access bond increases your total debt and monthly commitments. Banks will assess whether you can afford both bonds using the 30% DTI rule. Use our Second Property Calculator to see if the numbers work.
