Autónomo Tax Calculator Spain - Estimate take-home income after RETA and IRPF

Hi everyone 👋 This is my first time launching something on Product Hunt! I built this calculator because almost every future autónomo asks the same question: "If I earn €X per month, how much money will I actually keep?" Most guides explain tax forms and regulations, but very few show the number people actually care about: take-home income. This free calculator estimates: • Social Security contributions (RETA) • Income tax (IRPF) • Taxable profit • Monthly take-home income It also allows users to compare reduced-fee and standard contribution scenarios and see how deductible expenses affect their results. I originally built it for freelancers, remote workers and future autónomos trying to understand whether self-employment in Spain makes financial sense. I'd love to hear your feedback, suggestions, or ideas for future features. Thanks for checking it out! 🙌
