Transparent price intelligence

How PriceHistory.ai interprets price data

Our charts and recommendations are based on timestamped price observations stored by our tracking system. This page explains what each metric means, how confidence is assigned, and where shoppers should use their own judgement.

What counts as a price observation?

A price observation is a product listing price recorded at a particular time. We keep observations with their timestamps so shoppers can see how the listed price changed instead of relying only on a sale badge or crossed-out MRP.

Invalid test records are excluded from public history and calculations. Duplicate prices can remain useful because they show that a price persisted across multiple checks.

Unless a page explicitly says otherwise, bank discounts, card offers, coupons, exchange bonuses, delivery charges and personalised promotions are not included in the chart price. Confirm the final payable amount and seller on the retailer page before buying.

How the main metrics are calculated

Current price

The latest valid listing price recorded for the product. A retailer may change the price after our latest observation.

Recorded low and high

The lowest and highest valid prices in the period identified on the page. These are observations, not a guarantee about every price ever offered.

Average price

The arithmetic mean of valid price observations in the stated period. It is not the displayed MRP or a retailer-provided average.

Price trend

A comparison of recent valid observations. Small changes may be treated as stable to avoid overstating ordinary price movement.

How buy-or-wait guidance works

The buy score combines where the current price sits within its recorded range, its difference from the observed average, recent direction and the amount of usable history. The result is grouped into four simple labels: Excellent, Good, Fair or Poor.

It is a price-timing signal, not personal financial advice and not a product-quality rating. Stock, seller reputation, warranty, delivery, variant and your own urgency still matter.

Confidence levels

Low

Fewer than 10 valid observations. Treat the recommendation as an early signal.

Medium

At least 10 valid observations provide a more representative comparison.

High

At least 30 valid observations support the strongest confidence label used by the site.

Freshness and limitations

  • Prices can change between observations and may differ by seller, location, account, size, colour or other variant.
  • A recorded low means the lowest valid observation available to PriceHistory.ai for the stated period—not necessarily every price the retailer has ever shown.
  • Pages with insufficient or stale history may show limited insights and may be excluded from search indexing until the data becomes useful.
  • Always verify the final price, availability, returns and warranty terms with the retailer before completing a purchase.
