CalculaTudo is a Brazilian Portuguese online calculator portal covering scenarios such as health, finance, date and time, and math learning. The site emphasizes being “100% free” with no registration or login required, positioning itself as a self-service tool for individuals rather than a typical enterprise SaaS platform.
Its feature set is fairly broad. Health calculators include basal metabolic rate (TMB), TDEE, macronutrients, ideal weight, daily calories, and BMI. Finance tools support simple interest, compound interest, CDI, financing simulations, and comparisons between SAC and Price amortization methods. Date tools can calculate date intervals, business days, week numbers, and account for leap years and Brazilian national holidays. Math tools include the rule of three, weighted averages, triangle area, and the Bhaskara quadratic formula. Some tools provide charts, paginated detail tables, formula explanations, and step-by-step walkthroughs, giving the site a strong educational angle.
The site clearly states that all tools are free to use, with no monthly fees, hidden costs, or account requirements. Deployment is via online web access, with responsive support for mobile phones, tablets, and desktops. No information was found about self-hosting, enterprise private deployment, or offline versions.
From a SaaS or enterprise software perspective, CalculaTudo has obvious limitations: it does not disclose APIs, third-party integrations, batch calculation, team collaboration, role-based permissions, audit logs, or enterprise support. In terms of data security, the site says user inputs are processed locally in the browser and are not stored or shared on its servers. This is a plus for personal privacy, but it does not provide security certifications, compliance documentation, or an SLA.
Its strengths are that it is free, requires no registration, covers a wide range of scenarios, and provides relatively detailed explanations. It is suitable for students, beginners in personal finance, and general users who need quick estimates. The drawbacks are that results are for educational and informational reference only and cannot replace professional financial, medical, or investment advice. In addition, the rules are clearly tailored to Brazil, such as CLT, the Brazilian Central Bank, and Brazilian holidays, which limits business applicability for Chinese users.
No information is provided about access from China, so its availability is unknown. For occasional calculations, alternatives include Calculator.net, Omni Calculator, Excel/WPS templates, or domestic mini programs.
