Price rises 10% (20 to 22), volume drops 15% (100 to 85) = elasticity -1.5. Values below -1 mean demand is elastic (price changes hit volume hard). Above -1 (closer to zero) means inelastic (price changes don't affect demand much). Essential for pricing decisions.
Run it with sensible defaults
Using old price of 20, new price of 22, old volume of 100, new volume of 85, the calculation works out to -1.50. Nudge the inputs toward your own situation and the output recalculates instantly. The defaults are meant as a starting point, not a recommendation.
The levers in this calculation
The inputs — Old Price, New Price, Old Volume, and New Volume — do not pull with equal force. Frequency and unit price pull the total in different directions. The biggest surprise for most people is how small recurring amounts compound into large annual figures — that's where this calculation earns its keep.
How the math works
Standard price elasticity of demand formula. Negative values typical (higher price = lower demand). The working is transparent — you can verify every step yourself in the formula section below. No black box, no opaque "proprietary model".
What the score tells you
Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
Price elasticity produces a number based on the inputs provided.
