A lot of gold buyers have a shiny calculator on their website. You type in your jewellery’s carat and weight, a number pops up, and it feels reassuring. Here’s the problem: that number is rarely what you’ll actually be paid.
At Cash4Gold-Now, we made a deliberate decision not to have one — and this page explains exactly why.
The Problem With Online Gold Price Calculators
Gold price calculators look transparent. In reality, they only account for two variables: weight and carat. That’s the raw maths — not a real-world offer. The gap between a calculator’s output and the actual payout can be significant.
Here’s what most calculators don’t factor in:
- Hidden processing and refining fees — deducted after the estimate is generated
- Testing and administration charges — sometimes applied at the point of offer
- Your gold’s actual purity — calculators assume the carat you enter is accurate; they cannot physically test your item
- Non-gold components — clasps, stones, solder, and plating all reduce the true gold content but are invisible to a calculator
- Daily spot price timing — the live price shown at 9am may differ from the price applied when your gold is actually assessed
The result? A calculator tells you the maximum theoretical value of your gold, not what you’ll receive in your bank account.
The ASA Ruled on This for a Reason
This isn’t scaremongering — it’s regulatory history. The UK Advertising Standards Authority investigated a British gold buying company whose online cash-for-gold calculator was found to be misleading. A consumer made a complaint after being offered a significantly lower amount than the calculator had shown. The company argued the calculator was simply “an indication.” The ASA disagreed.
The ruling found that consumers would reasonably expect the figure shown and the actual offer to be close — and that no evidence existed to prove this was the case. The ASA ordered the advertisement to be withdrawn and instructed the company not to imply that calculator prices were close to what most consumers would actually receive.
If calculators were genuinely accurate, that ruling wouldn’t exist.
What a Calculator Cannot Replace
A number on a screen cannot do the job of an experienced valuer. At Cash4Gold-Now, every item is assessed by two qualified valuers. They check:
- The actual purity of your gold, platinum, or palladium using precision testing — not your guess based on a hallmark
- The true weight after separating any non-precious materials
- The live LBMA (London Bullion Market Association) spot price at the exact moment of valuation
- The full composition of your item — something no calculator can evaluate remotely
That’s why our offer reflects reality, not a best-case scenario that collapses once your jewellery arrives.
How We Calculate Your Price
Rather than a calculator, here’s exactly how your offer is worked out:
- We weigh your items with precision scales
- We test purity — we don’t take the hallmark at face value
- We check the LBMA spot price for gold, platinum, or palladium on the day we receive your items
- Senior staff members independently assess the offer
- We make you a firm offer based on that day’s live market price — you’re never quoted yesterday’s rate
If you accept, you receive payment within one hour via bank transfer. If you don’t accept, we return your items free of charge. No pressure, For parcels under 10g, a £15 admin fee may apply to cover secure return postage costs.
Why Calculators Benefit the Buyer, Not the Seller
Independent investigations into the UK postal gold market have uncovered offers that fell far short of independently verified valuations. In documented cases, sellers received a fraction of what their gold was actually worth — and in many instances, the companies involved had prominent calculator tools on their websites.
Calculators serve a marketing function: they generate a high number to draw you in. The real offer, presented after your gold has been posted, is often lower than that figure. And by that point, many sellers feel pressured to accept rather than go through the hassle of getting their items returned.
This is a well-documented pattern in the industry. A calculator on a website is not evidence of fair pricing. It’s often the opposite.
What to Do Instead of Using a Calculator
If you want a realistic sense of what your gold is worth before selling, here’s what actually helps:
- Check the live LBMA gold spot price (published daily, publicly available) and calculate your item’s theoretical maximum using the formula: weight in grams × purity percentage × spot price per gram
- Understand that refining and processing costs must come out of that figure — a fair buyer will tell you exactly what percentage of spot price they pay
- Ask any buyer directly: ”What percentage of today’s LBMA spot price will I receive for 9ct / 18ct gold?” If they can’t answer clearly, that’s a red flag
- Request your free gold selling pack from Cash4Gold-Now — once we assess your items, you get a firm offer from a real valuator, not an algorithm

Frequently Asked Questions
Why do other gold buyers have a calculator if it’s misleading?
A calculator on a website reduces hesitation and increases the number of people who post their gold. It looks like transparency — but the figure it generates is typically the best-case spot price with no deductions applied. The real offer comes after the gold is in their hands.
Can I use a gold price calculator to check if I’m being offered a fair price?
You can use one as a rough ceiling — the highest you could theoretically receive if there were zero fees, perfect purity testing, and no difference in spot price timing. Treat any calculator figure as a maximum, not an expectation. The actual offer will always be lower.
How do I know Cash4Gold-Now is giving me a fair price?
We base all offers on a percentage of the live LBMA spot price on the day we receive your items. We have over 15,000 Trustpilot reviews and a 4.8/5 rating from real customers.

No problem. We return your gold, platinum, or palladium completely free of charge. There is no obligation to accept at any point.
