Charm Pricing Calculator
Round prices to .99, .95 or .00 endings.
Nearest .99 price
$29.99
from a $30.00 target
Round to the nearest charm price, not the next one down — the difference compounds across a catalogue. Premium brands often use round numbers deliberately.
How the Charm Pricing Calculator works
Prices ending in 9 outsell round numbers in most consumer categories, an effect robust enough to survive decades of replication. It is not universal — premium and craft brands often round deliberately, because .99 signals discount.

Frequently asked questions
Does charm pricing actually work?
In mass-market consumer categories, yes — studies have found meaningful lifts from a 9 ending, partly through left-digit anchoring where £29.99 is processed as closer to £29 than £30.
When should I use round numbers instead?
Premium, luxury and handmade goods, and anywhere quality is the main claim. A £100 price signals confidence; £99.99 signals a deal. Services and B2B pricing also usually round.
What about .95 or .97 endings?
.95 reads slightly softer and is common in mid-market and European retail. .97 and .87 are associated with clearance in some chains. The ending carries a signal beyond the arithmetic.
How much margin does rounding down cost?
Usually a fraction of a percent, but it compounds. Rounding £30.00 to £29.99 costs 0.03% of revenue; rounding to £27.99 costs nearly 7%. Round to the nearest charm price, not the next one down.
