There’s a million handy calculators that allow you to just punch in the numbers without any work. My personal favorite is this one from “chicken dinner”. It comes preset with most of the 5e races and has all the point buy calculations worked out for you.
What is point buy & how does it work?
Point buy gives you complete control over your character’s stats, but it takes a bit longer than the “Standard Array” method and removes the potentially really high or low scores of the random “rolling” methods.
How do you find a buy point?
Use the highest level in the handle area and add at least a penny to derive the buy point. The double-bottom base is a bit different. The stock forms a cup pattern, but makes another correction before it reaches new highs. The second bottom usually is lower than the first. The pattern has a W-shape.
