This is actually really easy to find on the internet. Try to google and research before posting a question, it saves time :).
68% dark energy 27% dark matter 5% ordinary matter
In 2015 the Planck satellite consortium released an analysis of data collected by the Planck satellite that showed this percentage break down of the universe’s mass/energy.
Ordinary matter: 4.9%
Dark Matter: 26.8%,
Dark Energy: 68.3%
