Most calculators that rank skip the parts that change the answer: the mid-quarter and mid-month conventions, the order of Section 179 and bonus, the post-2025 bonus rules and the annual car limits. This one uses the IRS's own percentage tables, shows which table and Form 4562 line it used, and dates every figure.
