Rent vs Buy Calculator

From year 8, escalating rent (R 8,500 at 8.0%/yr) overtakes the full buying cost of R 13,981/mo. After that point the renter adds nothing new - only the existing portfolio compounds.

Model assumptions: Buy: 20-year bond term; property grows at 6.0%/yr; upfront costs (R 74,840) deducted from equity from day one. Rent + Invest: deposit invested at 10.0%/yr; monthly saving (buying cost minus rent, if positive) invested each month; rent escalates at 8.0%/yr. Income tax on investment returns and CGT on property sale are not modelled.

How it works

How this calculator models rent vs buy

Buy scenario: You take out a 20-year bond on the purchase price minus deposit. Each month you pay the bond repayment. The property grows in value at your specified appreciation rate. Net wealth at any year = property value minus remaining bond balance.

Rent scenario: You invest the deposit at your specified return. If the bond repayment exceeds your monthly rent, you invest the difference too. Net wealth at any year = the total value of your investment portfolio. Note that as rents escalate year on year, the monthly saving invested shrinks and can reverse.

What is not modelled: Transfer duty, conveyancing, bond registration costs, maintenance and repairs, rates and taxes, body corporate levies, insurance. All of these favour renting in the short term and should be factored into a more conservative break-even estimate - especially for the first few years.

When buying beats renting - and when it does not

Buying wins when: you stay 10+ years, property appreciates strongly (6%+), you have a reasonable deposit (10-20%), and investment returns in the rent scenario are moderate (8-10%). Buying also provides inflation protection - your bond repayment is fixed while rent escalates annually.

Renting wins when: you stay fewer than 5-7 years (upfront buying costs are not amortised), property appreciation is flat or negative, or you can invest the deposit at 12%+ consistently. Renting also provides flexibility - you can relocate without the cost and delay of selling.

The hidden advantage of buying: Leverage. You earn appreciation on the full property value (e.g. R1,500,000) even though you only put down R300,000. A 6% return on R1,500,000 is R90,000 per year in equity growth. You cannot replicate this with a cash investment of R300,000 at the same rate.

SA property appreciation - what to expect

Lightstone data shows that SA residential property has appreciated at roughly 6-8% per year in nominal terms over the past two decades, depending on the area. In real terms (after inflation at ~5%), the real return is 1-3% per year - modest but positive.

Coastal and estate properties in the Western Cape have outperformed the national average. Outlying towns and smaller metros have frequently underperformed. When choosing a 6% appreciation assumption, you are assuming roughly CPI-level nominal growth with a small real uplift.

Use a sensitivity approach: run the calculator at 4% (conservative) and 8% (optimistic) appreciation to bracket the likely range of outcomes. The break-even year is highly sensitive to this assumption.

Rent escalation and the long-term renter's risk

Rental escalation in SA has typically run at 7-10% per year, often tied to CPI plus 1-2%. Unlike your bond repayment - which stays fixed for the bond term - rent will compound upward every year. A rent of R8,500/month at 8% escalation reaches R18,340/month in 10 years.

This is one of the most powerful arguments for buying at the right time: your monthly housing cost is predictable and eventually your bond is paid off. Renters face perpetually rising costs with no endpoint and no asset to show for it after 20 years.

In this calculator the rent escalation is applied year by year. As rent rises above the bond repayment, the renter's monthly investable surplus shrinks and eventually turns negative - the renter can no longer invest the difference at all.

Frequently asked questions

Is it better to rent or buy in South Africa?

It depends on your time horizon, deposit size, and local market. Buying typically becomes more advantageous after 7-10 years when capital growth outweighs the higher initial costs and the bond repayment exceeds rent. Renting and investing the difference is competitive when investment returns are high relative to property appreciation.

What costs should I include when buying a property?

Include transfer duty, conveyancing fees, bond registration fees, monthly bond repayment, rates and taxes, levies (sectional title), insurance, and a maintenance reserve. This calculator models the bond repayment and compares wealth - use our Transfer Duty calculator to estimate the upfront buying costs.

How does property appreciation affect the rent vs buy decision?

Long-term SA property appreciation has averaged 6-8% per year in major metros. Higher appreciation strongly favours buying - it builds equity on the full property value (leverage). In flat or declining markets, renting and investing the deposit at 10%+ can outperform.

What return on investment should I use for the rent scenario?

Use the return you could realistically earn if you invested your deposit and monthly rental saving. The JSE All Share Index has returned approximately 10-12% per year over the long run before tax. A balanced fund with bonds and equities typically returns 8-10%. Use 10% as a reasonable middle estimate.

When does buying a property break even vs renting?

The break-even year depends heavily on your assumptions. This calculator shows the exact year at which your net worth under the buy scenario overtakes the rent-and-invest scenario. A lower deposit, higher appreciation, and slower rent increases all push the break-even year earlier.
