Home fibre in South Africa runs from roughly R400 a month for an entry line up to around R1,600 for a full gigabit. But the honest answer depends entirely on the speed you choose and which network reaches your street, so let’s unpack the real numbers.
The short answer
For an uncapped home line in 2026, most South Africans land somewhere between R500 and R1,000 a month. Entry-level 25 Mbps lines start from around R400, while a gigabit connection sits at roughly R1,200 to R1,600. Everything in between scales fairly smoothly with speed.
Those are ranges on purpose. There’s no single national price list, because the company that owns the cable at your home sets the floor, and then several ISPs compete on top of it. The only way to get your number is to check your address, but the ranges below will tell you what’s reasonable before you do.
Quick rule of thumb: a single 4K stream needs only about 25 Mbps. Most homes are genuinely happy on 50 to 100 Mbps, which keeps you in the R500 to R950 band rather than chasing a gig you’ll never fully use.
What fibre costs by speed (2026)
Here’s a realistic picture of uncapped monthly pricing across the common speed tiers. Treat these as typical bands, not quotes, since your actual options depend on the network at your home.
| Speed | Typical monthly price | Who it suits |
|---|---|---|
| ~25 Mbps | from ~R400 | Solo or a couple: browsing, one or two streams |
| ~50 Mbps | ~R500–R650 | Couple or small home, light work-from-home |
| ~100 Mbps | roughly R600–R950 | Small family, multiple streams + WFH |
| 200–300 Mbps | ~R900–R1,250 | Busy home: 4K, gaming, big downloads |
| ~500 Mbps | ~R1,000–R1,300 | Power users, lots of devices, uploads |
| ~1 Gbps | roughly R1,200–R1,600 | Heavy households, creators, big uploaders |
A useful real-world anchor: on a Telkom uncapped line, prices range from around R549/mo at 25 Mbps up to roughly R1,559/mo for a gig, which maps neatly onto the bands above. Other ISPs on the same line may sit a little higher or lower.
Not sure which row is yours? Speed is about how many things happen at once, not raw “fastness”. Our speed guide helps you right-size it, and uncapped fibre explained covers why almost every home line today is uncapped.
Why prices vary so much
South African fibre is open-access, and understanding that one idea explains almost every price difference you’ll see. The cable in the ground belongs to a fibre network operator (FNO), names like Vumatel, Openserve, Frogfoot, Octotel and MetroFibre. Your ISP rents capacity on that line and sends you the bill.
So the FNO at your address sets the floor price for each speed. A street served by a budget-friendly network will have cheaper entry deals than one served only by a premium network, before any ISP competes for you. You can see who owns what on our networks page.
On top of that floor, every ISP rides the exact same physical fibre. A 100 Mbps line is 100 Mbps whether you buy it from one provider or another; they can’t make the line faster. They compete instead on price, support, contract terms and the router they include. Compare them on our providers page.
The happy consequence: because the speed is identical across ISPs on a network, you can chase the lowest price for a tier without losing any performance. Two homes on the same road can still pay different amounts simply because different networks reach them.
What you’re actually paying for
Your monthly fee is really two things bundled into one debit order: the network line rental (the FNO’s share for the cable and capacity) and the ISP’s service on top. You almost never see them split out, but it’s why prices cluster the way they do.
Since the line is the same everywhere, the ISP portion is where your money buys real differences:
- Support: how quickly someone answers when your connection drops, and whether they’ll actually chase the FNO for you.
- Contract terms: month-to-month freedom versus a 12-month deal that usually unlocks free installation.
- Router: a basic unit versus a decent dual-band or mesh router that genuinely improves your Wi-Fi.
- Billing extras: some ISPs throw in a static IP, a landline, or a streaming perk.
None of those change your download speed, but a R100/month gap between two providers on the same line is almost always one of these, not a faster connection. Decide which you care about before you sort purely on price.
Once-off and first-bill costs
The monthly fee isn’t the whole story. A few upfront costs decide whether a “cheap” deal really is cheap:
- Installation: usually free on a 12-month contract. If you go month-to-month, expect a once-off setup fee of around R599 in exchange for no lock-in.
- Pro-rata first bill: activate mid-month and your first invoice is often heavier, since it bills the part-month you’ve used plus the next full month in advance. It settles down after that.
- Promo cliffs: “half price for three months” is lovely until month four, when the standard rate kicks in. Always note the end date.
- Router charge: some plans include the router; others sell or rent it separately. Check before you compare.
These trip up more people than any other part of a fibre bill. We walk through each one in avoiding fibre bill shock, and weigh the trade-offs in month-to-month vs contract fibre.
Rough budgeting tip: on a 12-month deal, budget your monthly fee plus a slightly larger first bill. On month-to-month, add the ~R599 setup once and you’re free to leave whenever you like.
How to pay less for the same line
You have more levers than you might think, and none of them mean settling for a slower connection.
- Right-size your speed. This is the biggest lever. Dropping from a gig to 100 Mbps can halve your bill, and most homes won’t notice the difference day to day.
- Compare ISPs on the same network. Identical line, different price, often R50 to R150 a month apart. Sort by the real monthly figure, not the banner.
- Pick the right contract. Staying put for a year? A 12-month deal usually waives installation. Might move soon? Month-to-month is worth the once-off setup.
- Re-compare once a year. Because switching ISP on the same line is quick and usually downtime-free, an annual check keeps you off the “loyalty tax”.

Find the cheapest fibre at your address
Because pricing is set by the network on your street and then contested by ISPs, there’s no shortcut around checking your specific address, but it only takes a moment. Run it, see which networks reach you, pick a speed that fits your household, then sort the ISPs on that line by their real monthly price.
That single check turns a confusing range of “R400 to R1,600” into the handful of deals that actually apply to your home, at the speed you need, for the lowest honest price. Start with your address and let the real options come to you.
