US Business & Self-Employed Calculators

Self-employed Americans handle several things W-2 employees don't see: self-employment tax at 15.3% covering both halves of FICA (with the deductibility of one half on the 1040), quarterly estimated tax payments due 15 April / 15 June / 15 September / 15 January, decisions about pass-through entity structure (sole prop, LLC, S-corp), and pricing decisions that have to clear the SE-tax wedge on top of income tax. The calculators in this hub cover each one — self-employment tax math, margin and markup for pricing, and break-even for the volume needed to cover fixed costs.
