About This Site
SideGigToolbox.com is built for people turning spare time into real income — furniture flippers, Etsy and craft sellers, freelancers, service-gig workers, and rideshare and delivery drivers. Our job is simple: give you the calculators and straight-talk guides to run that side gig like an actual business, not a guessing game.
Why this site exists
Most free calculators aimed at side hustlers stop at the surface — revenue in, nothing else considered. They skip depreciation, deadhead miles, materials cost creep, self-employment tax, and the dozen other things that quietly eat into what you actually keep. SideGigToolbox exists to close that gap: tools built around your real, net numbers, not just what lands in your inbox before expenses.

Built by someone who’s done it
SideGigToolbox is built and run by John Herwick, drawing on firsthand experience across furniture restoration and resale, rideshare driving, blogging, and mystery shopping — not just business theory. Read the full story on the About John page.
