Pricing Calculator for South African Businesses

Calculate SA selling price with SARS VAT 15%, payment-processor fees, and target margin pre-filled. Forward and reverse pricing for ZAR retail and B2B.

To calculate selling price from cost and target margin: Selling Price = Cost ÷ (1 − Margin ÷ 100). For a $20 cost at 40% target margin, the selling price is $33.33. Add VAT/sales tax on top where applicable (20% UK, 15% SA, varies by US state).

A South African pricing calculator converts cost to shelf price including 15% VAT, payment-processor fees (typically 2.5-3.5% via Yoco, PayFast, Peach, or Stitch), and your target margin. The R1,000,000 rolling 12-month turnover threshold for compulsory VAT registration is the single biggest pricing inflection point. SARS' VAT 404 Guide for Vendors is the authoritative reference.

SA pricing has three structural features absent in UK or US frameworks. First, the headline VAT rate (15%) is materially lower than the UK's 20% but higher than the average US state sales tax — and unlike US sales tax, SA VAT is charged on services as well as goods, with very few exemptions. Second, the R1 million turnover threshold for VAT registration is a notorious pricing cliff: cross it for the first time and your effective margin on existing customers drops 13% overnight unless you reprice. Third, the cash-vs-credit landscape is bifurcated — informal sector pricing assumes cash and instant payment, while formal B2B pricing assumes 30-60 day Net terms and the working-capital cost that implies.

Step 1 — Cost to ex-VAT price: apply your target markup to VAT-exclusive cost. If you're VAT-registered, your supplier's invoice will include 15% input VAT that you'll claim back via the VAT201 return — work in ex-VAT figures throughout, because that's how SARS sees your turnover on the ITR14.

Step 2 — Ex-VAT to shelf price: add 15% VAT. For zero-rated goods (basic foodstuffs: maize meal, brown bread, milk, eggs, vegetable oil, rice, fresh fruit and vegetables; international transport of passengers and goods; exports) the VAT rate is 0% — but you still register and file. For exempt supplies (residential rental, educational services, public road and rail transport, financial services) you don't register and can't claim input VAT.

SA pricing conventions by sector (industry-typical): - Builders' merchants: 25-40% markup on materials - Independent fashion retail: 150-250% (lower than UK/US due to import duty stack) - Restaurants and bars: 60-200% on food, 250-400% on alcohol - Professional services: 200-400% on direct staff cost - Plumbing / electrical parts: 30-100% depending on trade or retail counter

Worked example: a Pretoria retailer sources a kettle at R180 ex-VAT from a Johannesburg distributor (R207 incl-VAT, R27 input VAT claimable). Target 45% gross margin means ex-VAT shelf price = R180 ÷ 0.55 = R327.27. Adding 15% VAT, the till receipt shows R376.36 — round to R379 for psychological pricing. Net of payment-processing 3%, the retailer banks R367.50, of which R49.06 is output VAT owed to SARS at the next VAT201 cycle, leaving R318.44 — a R138.44 (43.5%) gross margin on a R180 cost.

For underlying rules, SARS' VAT 404 Guide for Vendors and the Binding General Ruling collection on the SARS website are authoritative. Pair with /profit-margin-calculator/za for the downstream margin walk and /invoice-calculator/za for the VAT-compliant invoice format SARS requires.

Frequently Asked Questions

How do I calculate the selling price from cost and margin?
Selling Price = Cost ÷ (1 − Desired Margin). This formula is used when you know your cost and the profit margin percentage you want to achieve. Example: cost $50, target margin 40% → Selling Price = $50 ÷ 0.60 = $83.33.
What is cost-plus pricing?
Cost-plus pricing means setting your price by adding a fixed markup to your cost. It is the simplest pricing method: know your cost, add your desired profit, and that is your price. The risk is that it ignores what the market will actually pay.
How do I price a service (not a product)?
For services, "cost" includes your time at a target hourly rate plus any direct expenses. Use the Freelance Rate Calculator to determine your minimum hourly rate, then use this tool to set project prices that achieve your target margin.
Should I include VAT/sales tax in my advertised price?
In the UK, consumer-facing prices must be displayed inclusive of VAT. In the USA, sales tax is typically added at checkout and not included in advertised prices. In South Africa, prices are generally displayed inclusive of VAT. This calculator handles all three conventions.
How does pricing affect profit margin?
A small price increase has a disproportionately large effect on margin. If your cost is $50 and you sell at $70 (30% margin), a $5 price increase to $75 raises your margin to 33.3% — a 10% improvement in profitability from a 7% price increase.
How does VAT registration in the UK or SA change my pricing?
Once you cross the VAT threshold (£90,000 turnover in the UK, R1 million in South Africa) you must add VAT to every invoice. If your customers are consumers, this effectively cuts your margin by 17–20% unless you raise prices. B2B customers usually reclaim VAT, so the impact is neutral. Plan the transition before you cross the threshold, not after.
What is the most common pricing mistake?
Pricing based on what feels reasonable rather than on cost plus target margin. Owners often anchor to a competitor's price without knowing whether the competitor is profitable, or set a round number ($99) that looks tidy but does not cover allocated overhead. Run every price through the calculator first; treat market and psychological pricing as adjustments, not the starting point.
What if my target margin is 100% or more?
A 100% margin is mathematically impossible — you would need to sell something for an infinite price (the formula divides by zero). The maximum sensible target is around 90%. If you genuinely want a very high margin, switch to markup-based pricing instead, where 1000% markup is well-defined and equals a 90.9% margin. The calculator caps margin entries at 99% for this reason.
I have my recommended price — should I just publish it?
Sanity-check it against three things first. One: competitor prices within your category — if you are 30%+ above or below the band, you need a story for why. Two: psychological price points ($49 vs $50, £99 vs £100). Three: round-up to absorb future cost rises. If the calculator says $73.14, publishing at $79 gives you headroom and looks deliberate rather than algorithmic.
How is pricing different from quoting?
Pricing sets a standard selling price for a repeatable product or service, designed to hit a target margin across many sales. Quoting is custom — it builds a one-off price for a specific client and scope, often including line items the standard price does not cover (travel, rush work, exclusivity). Use this calculator for pricing; quoting needs an itemised estimate template instead.
