About SoloMargins
SoloMargins was built with a simple mission: to provide independent workers, freelancers, contractors, and sole proprietors with frictionless, lightning-fast financial utilities.
Working for yourself brings immense freedom, but it also introduces complex overhead—especially around pricing, invoicing, payment processor fees, and self-employment tax calculations. Traditional business calculators are often hidden behind paywalls, bloated account registrations, or cluttered, slow interfaces.
SoloMargins is entirely free, runs completely client-side in your browser, and requires no registration or personal data sharing. Our focus is on speed, absolute transparency, and visual clarity, ensuring you can calculate margins instantly and get back to your work.
