Greggs Sausage Roll Inflation Tracker

Track how sausage roll prices have crept up over the years.

What is the Greggs Sausage Roll Inflation Tracker?

A Greggs sausage roll inflation tracker is a fun price-inflation calculator that shows how much a price has risen between two points in time and the average annual rate of that increase — using the sausage roll as a well-known, relatable British price reference. It works by calculating the total percentage change between an old price and a new price, then working out the compound annual growth rate needed to get from one to the other over the number of years between them, using the formula ((new ÷ old)^(1/years) − 1) × 100. To calculate it manually: percentage change = (new − old) ÷ old × 100 for the total rise, or use the compound annual growth rate formula for the yearly average — this tracks whatever two prices you enter rather than a verified official Greggs price history, since real historical prices aren't independently published.

How it works

This calculates the total percentage price increase between two prices you provide, along with the average annual rate of increase (compounded, not just a simple average) — the same underlying maths as calculating any inflation rate, just applied to whatever prices you personally remember or have researched, playfully framed around a beloved British bakery classic.

UK context

Everyday price inflation trackers like this are a popular, relatable way to feel real-world inflation in a way that abstract percentage figures from official statistics sometimes don't quite capture — a specific, familiar item's price creeping up over the years often lands more intuitively than a headline CPI figure.

Tips

For the most meaningful comparison, try to use prices from the same product and (as closely as possible) the same location, since prices can vary by region and even by individual shop.
The annual rate shown is compounded (accounting for the fact that increases build on each other year to year), which is more accurate than simply dividing the total percentage change by the number of years.

Frequently asked questions

Where do the prices in this calculator come from?

You enter them yourself — this tool doesn't use a verified official Greggs price database, it's a fun calculator for tracking any two prices you remember or have researched, with the sausage roll as a nostalgic, relatable theme.

Why is the annual rate different from just dividing the total % by the years?

Because price increases compound over time (each year's increase builds on the previous year's higher price), the compounded annual rate is the mathematically correct way to express a consistent yearly rate, rather than a simple average.
