How this calculator works
Switches = keys on the layout plus your spare percentage, rounded up to the next pack of 10. Switch cost = switches x price per switch. The total adds the kit, keycaps, stabilizers and extras.
Typical key counts: 60% about 61, 65% about 68, 75% about 84, TKL 87 and full size 104, with 4 stabilizers on most boards and 7 on full size.
