Charm pricing (999/995) variants & impact. The Psychological Pricing Calculator takes intended price and returns charm price (.99) plus charm price (.95), prestige price (round), revenue change per unit at the .99 price. Results update as you type, and the formula is shown under the result so you can repeat it in your own spreadsheet.
Pricing and sales metrics decide how much of the value you create you actually keep. Test price changes against margin, not volume alone, and measure the pipeline consistently so forecasts can be trusted. Use the worked example below to check the maths against your own figures.
How the Psychological Pricing Calculator works
Prices ending in 9 read as noticeably cheaper than round numbers and lift volume for value products; round prices signal quality for premium goods. The revenue impact of the charm ending is usually negligible.
Worked example
With the example values (intended price of $50), the charm price (.99) is $49.99; charm price (.95) $49.95, prestige price (round) $50.00, revenue change per unit at the .99 price -0.02%. Change any figure above and the result updates immediately; use Copy results to paste the summary into a note or email.

Frequently Asked Questions
How is charm price (.99) calculated?
.99 price = next whole number − 0.01; prestige price = rounded up to the nearest ten.
Which figures do I need?
Intended price. Take them from the same period and the same set of accounts or reports so the ratio is consistent, and check the example values as a guide to the units expected.
Should I test a price change before rolling it out?
Yes. Model the margin impact here first, then test on a segment or product line and measure volume and margin before applying it everywhere.
