Price Anchoring
Price anchoring places a higher reference price next to the focal price so the offer feels relatively cheaper. It's the most common pricing tactic on e-commerce PDPs — here's how it works and what kind of lift to expect.
Price Anchoring
Showing a higher reference price next to the focal price so the offer feels relatively cheaper.
Price anchoring is a pricing-psychology tactic where a higher reference number — the original price, a premium tier, a competitor's list price, or an RRP — is displayed alongside the price you want the shopper to pay. The first number sets a mental benchmark, and the focal price is then judged relative to that benchmark rather than on its own merits.
On product detail pages it shows up as the strikethrough original price, the 'compare at' field in Shopify, a three-tier pricing table that frames the middle option as the deal, or a 'You save €X' badge. Done well it lifts conversion and average order value; done lazily — or with anchors customers know are fictitious — it erodes trust and can trigger consumer-protection issues.
The mechanism is cognitive, not rational. The first number a shopper sees becomes the reference point their brain uses to evaluate everything that follows — a bias documented since Tversky and Kahneman's 1974 work on anchoring and adjustment. A €120 jacket marked down to €79 feels like a better deal than the same €79 jacket shown with no anchor, even though the purchase is identical.
Anchoring is the workhorse of pricing psychology because it's cheap to deploy and easy to test. Most Shopify themes ship with a 'compare at price' field, WooCommerce has 'regular' versus 'sale' price, and Magento exposes MSRP out of the box. The interesting work isn't whether to anchor — almost every store does — but choosing which anchor (original, RRP, premium tier, bundle) drives the cleanest lift for your category.
perceived_discount_pct = (anchor_price - focal_price) / anchor_price * 100
anchor_price
Anchor price
The higher reference price shown to the shopper (original, RRP, premium tier, or competitor).
focal_price
Focal price
The price you actually want them to pay.
perceived_discount_pct
Perceived discount
The discount magnitude the shopper internalises — the lever that drives the conversion lift.
An apparel store lists a winter parka with a strikethrough original price of €180 and a focal sale price of €126.
Anchor price: €180
Focal price: €126
→ 30% perceived discount
A 30% framed discount sits in the sweet spot where shoppers register the deal as meaningful but not suspiciously deep. Below ~15% the anchor barely registers; above ~50% it starts to look like the original was inflated, especially on commodity SKUs where buyers know the market price.
The lift from anchoring isn't uniform — it depends on category price elasticity, how recognisable the 'true' price is to your buyer, and the anchor type you choose. Apparel and beauty tolerate aggressive anchors because shoppers have weak reference points; consumer electronics tolerate almost none because every model has a public Amazon price two taps away.
Typical conversion lift from adding a price anchor to the PDP, by category and anchor type
| Category | Strikethrough original | RRP / MSRP | Premium-tier anchor | Notes |
|---|---|---|---|---|
| Apparel & accessories | +8% to +14% | +5% to +9% | +6% to +10% | Weak reference prices = high anchor tolerance |
| Beauty & personal care | +7% to +12% | +4% to +8% | +8% to +13% | Bundle/premium anchors work well for routines |
| Home & decor | +5% to +10% | +6% to +11% | +4% to +8% | RRP carries weight on branded furniture |
| Consumer electronics | +1% to +4% | +2% to +5% | +1% to +3% | Buyers price-check; aggressive anchors backfire |
| Supplements & food | +3% to +7% | +2% to +4% | +9% to +15% | Subscribe-vs-one-time premium anchor is strongest |
Treat these ranges as a starting hypothesis, not a target. The cleanest way to find your real number is an A/B test that holds the focal price constant and varies only the anchor — strikethrough versus no strikethrough, RRP versus original, premium-tier table versus single price — so you isolate the framing effect from any underlying discount.
Frequently asked questions
Yes, but with conditions. In the EU, Omnibus Directive rules require any 'previous price' shown alongside a sale price to be the lowest price the item sold for in the prior 30 days. In the UK and US, similar rules exist under CMA guidance and FTC pricing rules. Fabricated 'original' prices are the fastest route to a fine.
A discount is the actual reduction in price you're offering. Anchoring is how you frame that reduction — by showing the higher reference price next to the focal price. You can run a discount without anchoring (just lower the price silently), and you can anchor without a real discount (RRP or premium-tier comparisons). Most stores combine both.
Largely yes. The anchoring effect is robust even when people are explicitly told about it — it operates below deliberate reasoning. What erodes the lift is anchors shoppers don't believe: a €400 strikethrough on a €30 t-shirt reads as theatre and damages trust more than it helps conversion.
Directly adjacent to the focal price, with the focal price visually dominant — larger, bolder, or coloured. Shoppers need to see both numbers in one glance for the comparison to fire. Placing the anchor in a separate section or only showing it at checkout dilutes the effect.
For most DTC categories, 20-40% lands in the sweet spot — meaningful enough to register, modest enough to stay credible. Below 10% the anchor barely shifts perception; above 50% you start triggering skepticism and, in regulated markets, scrutiny of whether the original price is genuine.
Original price works better when you're a known brand and shoppers trust your pricing history. RRP (or MSRP) works better when you're a retailer carrying third-party brands and the manufacturer's price is the legitimate reference. Test both — they're rarely equally effective.
Only if you anchor against your own discounted prices indefinitely — then customers learn never to buy at full price. Anchoring against RRP, premium tiers, or competitor prices preserves margin because the focal price stays where you want it. The tactic is about perception, not necessarily a real markdown.
Anchoring is one of several pricing-psychology levers — alongside charm pricing (€19.99 vs €20), decoy pricing, bundle framing, and tier presentation. Anchoring shifts perception of magnitude; the others shift perception of value, choice, or precision. Most well-optimised PDPs use two or three in combination.
Yes — and you should. Hold the focal price constant and vary only the anchor display (shown vs hidden, strikethrough vs 'You save €X' badge, single price vs tier table). This isolates the framing lift from any price elasticity effect, so you know exactly what the visual change is worth.
Strongly, but the anchor changes. For subscriptions the most effective anchor is usually the one-time purchase price shown next to the subscribe-and-save price, not a strikethrough original. The comparison reframes the decision from 'should I subscribe?' to 'why would I pay more for one-time?'.
