I have been elected to build a new deck at my moms house. we are looking at a 21x16 wooden deck to replace the existing deck that was poorly built in the early 90's. I am planning for 2x10 joists, 4x4 deck posts since it's only a couple feet above ground, and 5x4 deck boards. I am figuring 60 2x10x12, 70 51/4x6x12, 10 4x4x8 deck posts, 32 joist hangers and about 100 pounds of screws. I'm sure I have to be missing something. What have I missed?
Stain or some other kind of finish. Maybe concrete footings, depending on your method of construction. Construction permit if required.
You'll have to choose your material - treated, cedar, redwood, or something exotic like ipe, synthetic, or combination of some or all of the above.
A plan?
There isn't any way for us to confirm a materials list without more details of what you are building.
At a glance, you have no materials for railings or steps, nothing for support girders, your joists appear to be sized incorrectly, your deck boards seeem to be the wrong length, you have no hardware for connecting to your 4x4 support posts, no foundation materials or post bases, and I think you have way too many screws.
But I'm doing a lot of guessing without more details of the plan.
When I did mine last year the menards deck builder tool was the easiest way for me to get an idea of the full materials needed. It still took a lot of reading through the local code to tweak it for what I needed.
Two things I did that I really like:
Stainless cable railings, used muzata brand hardware from Amazon and it wasn't very expensive, maybe slightly more than wooden pickets.
Ordered 20' long deck boards so I could run the whole length with no joints.
If it's a wet area, consider putting some joist tape on top of the wood to protect it from rotting from above when water sits on the top edge for long periods.
A palm nailer will really help with all of those joist hanger nails.

And wear hearing protection!
I fully recommend using composite deck boards. The required maintenance is soooo much less!
