Quick Answer: Unsecured business loan interest rates in South Africa range from 1% to 6% per month depending on the lender and your business’s risk profile. Yalu’s lending partners charge a fixed rate of 4.17% per month — equivalent to 25% over a 6-month term. There are no initiation fees charged to your business, no monthly service fees, and no early settlement penalties. A R500,000 loan over 26 weeks costs R125,000 in interest, making the total repayable R625,000 at R24,038 per week.
When you’re considering a business loan, the interest rate is only part of the story. The questions that actually matter for your cash flow are: how much do I repay each week, for how many weeks, and what does this cost my business in total? This page answers all of those — plainly, with real numbers, no jargon.
Yalu arranges unsecured business loans of up to R6 million for established South African businesses with R1 million or more in annual turnover and 12 months or more of trading history. The rate and cost structure below reflects loans arranged through Yalu’s accredited lender network.
Key Takeaways
How unsecured business loan interest works in South Africa
South African private lenders charge interest on business loans differently from the way banks charge interest on home loans or vehicle finance. Understanding the difference prevents expensive miscalculations.
Banks typically use an amortising interest model — you pay a blended monthly instalment that starts heavily interest-weighted and gradually shifts to paying more principal. The annual rate is quoted as a percentage of the outstanding balance, which decreases as you repay. This model works well for long-term loans over 5–20 years but is unnecessarily complex for short-term working capital.
Private lenders and Yalu’s lending network use a flat fee model. Interest is calculated once, upfront, as a fixed percentage of the principal loan amount. It is added to the principal to arrive at the total repayable figure. This total is then divided evenly across the repayment term into equal weekly instalments.
This means:
- You know the full cost before you sign — there are no surprises mid-term
- Your weekly repayment is identical every week — easy to budget for
- Repaying early saves you nothing on the interest already baked in — but there are no penalties either
Yalu’s rate: 4.17% per month, fixed
This translates to:
- 13-week term (3 months): 12.5% total interest on the principal
- 26-week term (6 months): 25% total interest on the principal
A R1,000,000 loan over 6 months costs R250,000 in interest. Total repayable: R1,250,000. Weekly repayment: R48,077. That is the full cost — nothing hidden, nothing variable.

Use this as your first reference when assessing whether a Yalu loan fits your cash flow. The loan calculator lets you model any amount within the R50,000–R6,000,000 range.
13-week term (3 months)
| Loan amount | Interest (12.5%) | Total repayable | Weekly repayment |
|---|---|---|---|
| R100,000 | R12,500 | R112,500 | R8,654 |
| R150,000 | R18,750 | R168,750 | R12,981 |
| R250,000 | R31,250 | R281,250 | R21,635 |
| R400,000 | R50,000 | R450,000 | R34,615 |
| R500,000 | R62,500 | R562,500 | R43,269 |
| R750,000 | R93,750 | R843,750 | R64,904 |
| R1,000,000 | R125,000 | R1,125,000 | R86,538 |
26-week term (6 months)
| Loan amount | Interest (25%) | Total repayable | Weekly repayment |
|---|---|---|---|
| R100,000 | R25,000 | R125,000 | R4,808 |
| R250,000 | R62,500 | R312,500 | R12,019 |
| R500,000 | R125,000 | R625,000 | R24,038 |
| R750,000 | R187,500 | R937,500 | R36,058 |
| R1,000,000 | R250,000 | R1,250,000 | R48,077 |
| R1,500,000 | R375,000 | R1,875,000 | R72,115 |
| R2,000,000 | R500,000 | R2,500,000 | R96,154 |
How to use this table: Find the loan amount closest to what you need. Look at the weekly repayment figure. Ask yourself: does my business receive enough in weekly revenue, after existing obligations, to absorb this repayment comfortably? If yes without strain — the loan is affordable. If it’s tight — consider a smaller amount or longer term. If it’s not achievable — the loan is too large for your current cash flow.
How Yalu’s rate compares to other private lenders
Private lender rates in South Africa are not regulated by a single price ceiling the way personal loans are under the National Credit Act. Business lending rates are set by each lender based on their assessment of risk, cost of capital, and operational model. Here is where the market sits in 2026:
| Lender type | Typical rate range | Term | Collateral | Speed |
|---|---|---|---|---|
| Traditional banks (Nedbank, ABSA, FNB, Standard Bank) | Prime + 3–8% (roughly 13–18% per annum) | 1–5 years | Usually required | 3–8 weeks |
| Fintech lenders (Bridgement, Lula, Merchant Capital) | 2–5% per month | 3–24 months | None | 24–72 hours |
| Yalu lending network | 4.17% per month (fixed) | 3–6 months | None | 24–48 hours |
| Business credit cards | Prime + 8–14% (roughly 18–25% per annum) | Revolving | None | Immediate (if pre-approved) |
| Unregistered lenders | 10–30%+ per month | Variable | Variable | Immediate |
The honest comparison: Yalu’s 4.17% per month sits mid-market among private lenders. It is higher than a bank rate — but banks take 3–8 weeks and require collateral. The true cost comparison is not bank rate vs Yalu rate in isolation. It is: what does the bank loan cost you when you factor in the time value of capital, the opportunity cost of waiting, and the risk of putting assets up as security?
For a business that needs R500,000 to fulfil a confirmed R2,000,000 purchase order, a 6-month Yalu loan costing R125,000 in interest is not expensive relative to the revenue it enables. For a business that needs working capital to cover a payroll shortfall while waiting on a client payment, the alternative to a R8,654/week repayment isn’t a cheaper loan — it’s a missed payroll and the reputational and legal consequences that follow.
Fixed rate vs variable rate: why it matters for your cash flow
Yalu’s rate is fixed at the time of your loan agreement. It does not change if the South African Reserve Bank adjusts the repo rate — upward or downward — during your repayment term.
The current SARB repo rate sits at 6.75% (March 2026), giving a prime lending rate of 10.25%. Banks that offer prime-linked business loans will adjust your repayment if prime changes. For a short-term loan of 13–26 weeks, a rate adjustment mid-term is unlikely to be significant. But for a business that is tight on cash flow margin, any unexpected change to a repayment amount is unwelcome.
With a fixed rate, your weekly repayment is the same from week one to the final week. No surprises. This is by design — it makes weekly cash flow planning straightforward and removes the uncertainty that variable-rate products introduce.
What fees are charged on a Yalu loan?
This is worth stating clearly because fee structures vary significantly across South African lenders, and opaque fee arrangements are common.
What Yalu charges your business: nothing.
Yalu’s facilitation fee is paid by the lender that concludes your loan — not by you. There is no initiation fee deducted from your loan proceeds, no monthly service fee added to your repayments, and no early settlement penalty if you repay ahead of schedule.
The total cost of your loan is: principal + interest at 4.17% per month. That is the complete figure. No additional line items.
What to watch for with other lenders:
Some lenders quote a headline interest rate and then add initiation fees of R1,200–R6,000, monthly service fees of R69–R290, and in some cases credit life insurance premiums. Under the National Credit Act, all of these must be disclosed in the pre-agreement statement — but many business owners sign without reading the full cost of credit figure. Always ask for the total repayable amount — principal plus all fees plus all interest — before signing.
Is business loan interest tax deductible in South Africa?
Yes — with an important qualifier that your accountant should confirm for your specific situation.
Under SARS rules, interest paid on money borrowed for the purposes of producing income is generally deductible as a business expense. If your Yalu loan is used for working capital, stock purchases, payroll, equipment, or any other income-producing business purpose — which is almost always the case — the interest portion of your repayments is a deductible expense.
What this means in practice:
A business paying a corporate tax rate of 27% that borrows R1,000,000 over 26 weeks at 4.17%/month incurs R250,000 in interest. If that R250,000 is fully deductible, the tax saving is R67,500 — reducing the effective net cost of the interest from R250,000 to R182,500.
The loan principal itself is not deductible — you borrowed money and you’re repaying it, which is neutral for tax purposes. Only the interest component qualifies as a deductible expense.
This is a material consideration when comparing the true cost of a Yalu loan against alternatives. Always confirm the applicable deductibility with your accountant and the current SARS treatment before making decisions based on tax assumptions.
How to assess whether the cost is right for your business
The question is not “is 4.17% per month cheap?” The question is: “does the return on this capital exceed its cost?”
Three scenarios where the answer is clearly yes:
Scenario 1 — The purchase order.Â
Your business is offered a R3,000,000 purchase order from a blue-chip client. The fulfilment cost is R1,800,000. You have R900,000 available. You borrow R900,000 at 4.17%/month over 26 weeks — cost: R225,000. Net margin on the PO after loan cost: R3,000,000 minus R1,800,000 minus R225,000 = R975,000. The loan cost is 23% of the net margin. This is straightforward.
Scenario 2 — The payroll gap.Â
Your business has R180,000 in outstanding invoices from a client who is 45 days late paying. Payroll of R120,000 is due in five days. You borrow R120,000 over 13 weeks — cost: R15,000. The alternative: missing payroll, risking losing key staff, and damaging employee trust that took years to build. The R15,000 loan cost is the cost of protecting your team and your operational continuity.
Scenario 3 — The seasonal bridge.Â
Your business generates R300,000/month in peak season and R80,000/month in your four quiet months. Fixed costs are R160,000/month. You borrow R320,000 over 26 weeks to bridge the quiet period — cost: R80,000. The business continues operating at full strength, staff are retained, and supplier relationships are maintained. The R80,000 cost buys 4 months of uninterrupted operations.
In each case, the question is whether the business outcome justifies the financing cost — not whether the rate is low in absolute terms.

Frequently asked questions
What is the interest rate on a Yalu unsecured business loan?Â
Yalu’s lending partners charge a fixed rate of 4.17% per month on the principal loan amount. Over a 13-week (3-month) term this equals 12.5% total interest. Over a 26-week (6-month) term it equals 25% total interest.
Is the interest rate fixed or variable?Â
Fixed. The rate is set at the time of your loan agreement and does not change during the repayment term — regardless of any SARB repo rate movements.
Are there any fees on top of the interest rate?Â
No fees are charged to your business. There are no initiation fees, monthly service fees, or early settlement penalties. Yalu’s facilitation fee is paid by the lender.
How is the weekly repayment calculated?Â
The total repayable amount (principal plus interest) is divided equally across the number of weeks in the repayment term. For a R500,000 loan over 26 weeks: R625,000 ÷ 26 = R24,038 per week, collected by weekly debit order.
Is business loan interest tax deductible in South Africa?Â
Generally yes — interest paid on money borrowed for income-producing business purposes is deductible as a business expense under SARS rules, reducing your taxable income. Confirm the specific treatment with your accountant before filing.
How does Yalu’s rate compare to bank business loan rates?Â
Banks typically charge prime-linked rates of 13–18% per annum on secured business loans — which sounds lower than Yalu’s 4.17%/month. However, bank rates apply to longer-term secured loans with collateral requirements and approval timelines of 3–8 weeks. Yalu’s rate applies to short-term unsecured loans approved in 24–48 hours. These are structurally different products serving different needs — they are not directly comparable on rate alone.
Can I repay my loan early?Â
Yes. There are no early settlement penalties. However, because interest is calculated upfront as a flat fee on the principal rather than on a declining balance, early repayment does not reduce the total interest charged.
What is the maximum loan amount available?Â
R6 million for qualifying businesses with R1M+ annual turnover and 12+ months of trading history.
