Rental vs Bond Calculator
Convert your monthly rent into a property price you can afford — or find out what rent to charge to cover your bond as a landlord
The "same payment" property price uses 100% of your rent for the bond — leaving nothing for rates, levy, insurance, and maintenance. The comfortable price uses only 80% of your rent for the bond, keeping R 1 600/mo for ownership costs.
| Rent | Same Payment Property | Comfortable Property |
|---|---|---|
| R 5 000/mo | R 609 350 | R 507 480 |
| R 7 000/mo | R 813 090 | R 670 472 |
| R 8 000/mo | R 914 960 | R 751 968 |
| R 10 000/mo | R 1 118 700 | R 914 960 |
| R 12 000/mo | R 1 322 440 | R 1 077 952 |
| R 15 000/mo | R 1 628 050 | R 1 322 440 |
| R 18 000/mo | R 1 933 660 | R 1 566 928 |
| R 20 000/mo | R 2 137 400 | R 1 729 920 |
| R 25 000/mo | R 2 646 750 | R 2 137 400 |

From Rent to Bond: Understanding the Conversion How to use • Formula • Example
How to Use This Calculator
The Rent to Bond tab answers: "If I'm currently paying R8,000/month rent, what property can I afford at the same monthly payment?" Enter your current rent, available deposit, interest rate, and bond term. The calculator shows the maximum property price where the bond equals your rent, plus a more comfortable price that keeps 20% of your rent free for ownership costs.
The Bond to Rent tab is useful for landlords: given a property price and bond terms, what rent do you need to charge to cover all costs — bond, rates/levy, insurance, and maintenance?
The Conversion Formula
Max Property = Max Bond + Deposit Available
Where r = monthly interest rate (annual rate / 12) and n = total number of monthly payments. At 10.25% over 20 years, every R1,000/month rent translates to approximately R111,000 in bond affordability.
Worked Example
Nomsa pays R9,500/month rent in Durban. She has R120,000 saved as a deposit. At 10.25% over 20 years:
Maximum bond where payment = R9,500: approximately R963,000.
Add her deposit: R963,000 + R120,000 = R1,083,000 property.
However, owning a R1,083,000 property would cost roughly R1,100/month in rates, levy, and insurance — leaving nothing for emergencies. The "comfortable" calculation uses 80% of her rent (R7,600) for the bond, giving her a R890,000 property and keeping R1,900/month for ownership costs.
Frequently Asked Questions
If I pay R8,000 rent, what bond payment can I afford in South Africa?
At R8,000/month with a 10.25% rate and 20-year term, your bond amount is approximately R789,000. With a R100,000 deposit, you can afford a property of approximately R889,000 at the same monthly payment. However, note that owning also involves rates, levy, insurance, and maintenance of roughly R750–R1,200/month extra, so a "comfortable" property price would be around R760,000–R800,000.
What extra costs does owning a property have beyond the bond payment?
Beyond the monthly bond repayment, homeowners typically pay: municipal rates and taxes (0.5–1% of property value per year), sectional title levy (R500–R3,000/month depending on complex), building insurance (0.1–0.2% per year), and a maintenance budget (1% of property value per year is recommended). Combined, these can add 1–2% of the property value annually, or R1,000–R2,500/month on a R1.5 million home.
What gross rental yield do I need as a landlord to cover all costs?
To cover bond, rates, levy, insurance, and maintenance, most South African landlords need a gross rental yield of 8–12% per year. In practice, many landlords only achieve 6–8%, meaning the property runs at a small loss each month that is offset by capital appreciation over time. The Bond to Rent tab calculates your specific break-even rent based on your property price and bond terms.
Is it better to rent or buy in South Africa in 2026?
This depends on your situation. Buying builds equity and provides long-term security, but requires a deposit (typically 10%), has significant upfront transaction costs (transfer duty, conveyancing fees, bond registration), and locks up capital. Renting offers flexibility but builds no equity. As a rule of thumb, if your rent is significantly less than the equivalent bond payment on a similar property, renting and investing the difference can be competitive. Use our Buy vs Rent Calculator for a full long-term comparison.
How much deposit do I need to keep the same monthly payment when buying?
The larger your deposit, the lower the bond and therefore the lower the monthly payment. If you want to buy a R1,500,000 property but only qualify for R1,200,000 bond (based on your rent budget), you need at least R300,000 as a deposit. A 10% deposit is typically the minimum that most SA banks prefer, though 100% bonds (no deposit) are sometimes available to credit-worthy first-time buyers.
