Cologne vs Perfume vs EDT vs EDP: The Simple Guide

The labels sound like they mean four different products. They don’t. Parfum, eau de parfum, eau de toilette and cologne all describe the same thing at different strengths: how much fragrance oil is dissolved in the alcohol. More oil means it lasts longer and projects more. That is essentially the entire difference, and once you know it, the pricing and the marketing make a lot more sense.

The concentration table

Here is how the four common labels stack up. The oil percentages are approximate ranges — brands vary, and the categories overlap — but the ordering is consistent and the wear times are what the community typically reports.

So what should you actually buy?

For most people, an eau de parfum or eau de toilette is the sweet spot. EDP if you want richness and longevity; EDT if you want something lighter for daytime and heat. True parfums are wonderful but expensive and often overkill for daily life, and genuine eau de cologne fades so fast it’s more of a refreshing splash than a signature. When a scent comes in several concentrations, the EDP is usually the best-value “buy once” choice.

A note on the word “cologne”

Confusingly, in everyday American English “cologne” just means “a men’s fragrance,” the way “perfume” means a women’s one — regardless of the actual concentration. So a men’s “cologne” on the shelf is very often an eau de toilette or eau de parfum, not a true EDC. When we say “best cologne” across this site, we mean it that everyday way. Check the bottle for the real concentration if longevity matters to you.

Once the labels make sense, the next question is how to make whatever you buy actually last — which is only partly about concentration. Read how to make cologne last longer, or jump straight to the best colognes of 2026.
