Perfume Dilution Calculator

Work out perfume dilution instantly with clear inputs, formula shown and shareable results.

About Perfume Dilution Calculator

The amount of pure oil is fixed, so the finished volume is that oil divided by the target concentration and the diluent is the difference from what you started with. Fragrance families are defined by concentration bands, which is why the same accord becomes an eau de toilette or an extrait purely through dilution.

Formulas

Finished volume

total ml = concentrate ml x concentrate strength / target concentration

Diluent

alcohol to add = finished volume - concentrate volume

Worked example

With the default values below, Perfume Dilution Calculator returns Perfumer's alcohol to add of 60.00. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

  • The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
  • In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
  • Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is the Perfume Dilution figure worked out?

total ml = concentrate ml x concentrate strength / target concentration. The amount of pure oil is fixed, so the finished volume is that oil divided by the target concentration and the diluent is the difference from what you started with.

Why does this matter?

Fragrance families are defined by concentration bands, which is why the same accord becomes an eau de toilette or an extrait purely through dilution.

What do I need to enter?

Enter fragrance concentrate, target concentration, concentrate strength. The defaults shown are a realistic worked example — swap in your own figures to get a result you can use.
