How would I level up every 5 wins?

Hello, I am making a game, I have got the leaderstats set up (cash,wins, level) and now the only thing left to do is add a level up system.

So I plan on adding this in the function that is called at the end of each round.

QUESTION: How would I increase the level every 5 wins?

thanks

UPDATE: I found a way to do it, works so far.

increase the wins leaderstat and add a script that increases the level for every 5 wins. Make it use plr added to check every player. It should be a serverscript.
