Most companies make the same mistake. They collect competitor prices, look at the numbers… and do nothing. Or they act randomly: cut 5% today because a neighbour did, raise tomorrow because “an expert said so”.
Pricing strategy is not a reaction. It is control — and you cannot control without numbers.
At Smyalichi we have reworked hundreds of price matrices and singled out seven metrics that actually move profit. Each one is a KPI you can calculate, track, and use in decisions.
1. Price Positioning Index (PPI)
What it shows: how much your price sits above or below the market on average across the assortment.
How to calculate:
PPI = (Your price / Average competitor price) × 100 PPI = 100% — you are in line with the market PPI > 100% — you are more expensive than the market PPI < 100% — you are cheaper than the market
Why it matters: one SKU can be higher, another lower; PPI shows the overall trend. If you position as premium, PPI should stay clearly above 105%. Value-for-money — around 100%. Discounter — below 95%.
How to use it: track PPI month over month. A sharp drop without a strategy change is a signal to check key SKUs.
2. Price elasticity of demand
What it shows: how a change in your price affects sales volume.
How to calculate (simplified):
Elasticity = (% change in sales) / (% change in price) >1 — elastic demand: a price cut can grow revenue <1 — inelastic demand: you can often raise price with limited volume risk
Why it matters: not every SKU needs a price cut; some deserve increases. Elasticity shows where customers are price-sensitive.
How to use it: once a quarter, estimate elasticity for your top 20 SKUs. Above ~1.5 — candidates for promos and price containment; below ~0.5 — safer indexation.
3. Red zone share
What it shows: the share of assortment where you are more than 10% above the nearest competitor.
How to calculate:
Red zone = (SKUs where your price > min competitor price × 1.1) / (Total SKUs) × 100
Why it matters: buyers compare. +10–15% on a hero SKU often means churn; +3–5% may be fine if service is strong.
How to use it: aim for red zone below ~15% on your top 100. If it grows, cut hero losses or strengthen your value story (delivery, warranty, perks).
4. Reaction speed
What it shows: how many days pass after a competitor changes price before you respond.
How to calculate: median across reactions in a month.
Why it matters: markets move faster. Reacting in two to three weeks means you miss the demand spike. Ideal: 24–48 hours.
How to use it: automate alerts. When a competitor moves a top SKU, your monitoring stack (for example price.smyalichi.ru) should ping the owner. Measure how median reaction time drops after automation.
5. Price Stability Index (PSI)
What it shows: how often you change prices versus competitors.
PSI = (Your price changes per month) / (Average competitor changes per month) PSI < 0.8 — you change slower than the market (you may miss windows) PSI ≈ 1 — you move with the market PSI > 1.2 — you change faster (you may train customers to wait for discounts)
Why it matters: too many changes erode trust; too few make you rigid. Balance is key.
How to use it: benchmark against the market leader, not the average. If the leader reprices weekly and you do monthly, you may be too slow; if the opposite, you may be over-twitchy.
6. Anchor price share (APS)
What it shows: the share of “anchor” items shoppers use to judge whether you are expensive.
How to calculate: pick 5–10 anchors (e.g. “brain MRI” or “iPhone 16 Pro 256 GB”) that people always compare.
APS = (Anchors where you are not above market) / (Total anchors) × 100
Why it matters: even if the long tail is higher, strong anchors bring traffic; weak anchors lose the click before the rest of the assortment is seen.
How to use it: track APS daily if you can — it is your market “pass”. Target 100% on top five anchors.
7. Gap to leader (GTL)
What it shows: how far you trail or lead the main competitor in your segment.
How to calculate: pick one leader (not necessarily the priciest — the most aggressive in your lane).
GTL = (Your price − Leader price) / Leader price × 100 Negative — you are cheaper (attack mode) Positive — you are more expensive (defence mode) 0% to +5% — often a comfort band > +10% — high risk of being priced out
Why it matters: the leader sets rhythm. Ignoring their cuts is dangerous; blind copying is also wrong. GTL tells you how safe your spread is.
How to use it: track GTL daily. If the gap shrinks (they catch up), prepare a response. If it widens (you pull ahead), check share — sometimes +5% with better service is optimal.
Bonus: target KPI bands
| Metric | Green | Yellow | Red | Cadence |
|---|---|---|---|---|
| PPI | 95–105% | 90–94% or 106–110% | <90% or >110% | Weekly |
| Red zone | <15% | 15–25% | >25% | Weekly |
| Reaction speed | <48 hours | 48–120 hours | >120 hours | Per event |
| APS (anchors) | 100% | 80–99% | <80% | Daily |
| GTL | −5% to +5% | −10% to −5% or +5% to +10% | <−10% or >+10% | Daily |
How to roll this out without pain
Manually computing all seven KPIs for 500 SKUs and five competitors is not sustainable. Either:
- assign a part-time analyst to wrangle spreadsheets and weekly decks, or
- automate with a price monitoring service.
We recommend the second path. price.smyalichi.ru collects competitor prices daily and surfaces these metrics on dashboards — not just “competitor prices”, but a pricing control loop.
Even if you start in Excel, start. Three to four weeks of disciplined calculation will change how you see the market.
