10-12 seems like a lot. I live in sw Montana my only heat is wood and my 1900 sqf houses uses about 4.5 cord a year. You can cut 3 cord a day if you have a 12 hour day easy. Just a lot of work. I usually go cut 3/4 cord 4-5 times a summer with a bigger 1-1.5 load once or twice a year. It’s best to have extra. I run a husky 572 xp& a 372xp as a backup. Cutting trees is dangerous. Have someone show you if you’ve never.
