How to use the Inverse Variation Calculator

Find the constant of inverse variation and predict a corresponding y-value when y = k/x. Enter the requested values and select Calculate. The result and supporting values are produced locally in your browser.

Formula

k = xy; then y₂ = k ÷ x₂

Worked example

If y = 10 when x = 4, then k = 40 and y = 5 when x = 8.

What to keep in mind

  • Inverse variation assumes the product xy remains constant.

Methodology

This calculator uses deterministic arithmetic and performs the calculation locally in your browser. Verify assumptions, units, and source values for your specific use case.
