Rent vs buy calculator
Work out the monthly rent where renting and buying cost about the same. Built around transfer duty, home loans, and the growth your deposit could have earned if you rented instead.
The home
Tap the price to type your own amount. You can enter more than R6 million.
The home loan
Default is today's SA prime lending rate (10.75%).
Monthly home loan repayment
R16,447
Growth
Home growth vs rent escalation drive this a lot (defaults 5% / 6%).
How we got there
Follow the cash: what you put in, what you pay while you live there, and what you get back when you sell. That story sets the break-even rent above.
1. Cash you put in up front
Total cash at purchase
R284,222
Deposit
R180,000
Transfer duty
R21,786
Lawyer fees (transfer + bond)
R79,936
Other buying costs / renovations
R2,500
2. Costs while you live there (7 yrs)
Home loan repayments
R1,381,524
Principal repaid
R240,785
Interest
R1,140,739
On a long home loan, most of what you pay is interest.
Rates, upkeep, insurance, utilities, levies
R558,133
3. What you get back when you sell
Sale price
R2,532,781
Minus agent commission
-R151,967
Minus capital gains tax
-R0
Minus still owing on the home loan
-R1,379,215
Cash you walk away with
R996,599
If you rented instead
Cash a renter would pay over the same stay, at the break-even rent (it rises each year).
Rent over the stay
R1,383,789
Utilities + contents insurance
R216,517
So break-even rent is R13,738/month (then rises each year). The tip already includes what the deposit and extra costs could have earned if invested. We don't show that growth as a cash line next to the sale, because it isn't money in your pocket.

How we calculate break-even rent
Break-even rent is the monthly rent where the all-in cost of renting and buying look about equal over your years in the home. We compare ownership cash flows (deposit, fees, bond, rates, maintenance, and sale costs) with renting plus investing money you would otherwise lock in a deposit and extra ownership costs.
SA costs baked in (transfer duty, bond, CGT)
The calculator includes SARS transfer duty, Law Society guideline conveyancing and bond registration fees with VAT, the ownership costs you enter, and primary-residence capital gains tax assumptions when you sell. Defaults use SA prime for the home loan rate. You can change any input.
When renting usually wins
Renting can look better when you will not stay long, purchase costs are high relative to rent, or you would reliably invest the deposit and monthly difference. Buying can look better when you stay longer, similar rents are high, and home growth outpaces your alternatives. Use the break-even rent number against real listings near you.
Sources and assumptions
- Transfer duty from the SARS schedule (SARS Transfer Duty tables effective 1 April 2025 (unchanged 1 April 2026)).
- LSSA Conveyancing Fee Guidelines effective 1 July 2026 (excl. VAT; +15% VAT applied).
- Main-home capital gains exclusion defaults to R3,000,000 from 1 March 2026. See SARS Budget 2026 FAQ. Inclusion rate 40%.
- Default home loan rate is SA prime (10.75%; ≈ repo + 3.5pp).
- Break-even rent approach is in the same spirit as Rolling Alpha's rent-or-buy calculator. Assumes you would invest the deposit and any monthly saving if you rented.
- A planning tool, not financial, tax, or legal advice. Home loan rates are usually floating in SA. We treat the rate you enter as constant.
