About elCalculador
Free, precise, multilingual calculators for everyone — from students and homeowners to entrepreneurs and scientists.
Our Mission
elCalculador was built on a single belief: everyone deserves access to accurate, professional-grade calculation tools — regardless of their language, location, or budget. We built elCalculador to be that resource.
The name is Spanish — and intentional. Spanish is the second most spoken language on the internet, with over 500 million speakers across Latin America, Spain, and the United States. elCalculador was named to reflect our commitment to the Spanish-speaking world, while our platform serves users in English, French, Arabic, and Hindi too.
What We Cover
Our 21 calculators are organized into four categories built around what people actually need to calculate in real life:
Finance & General — Mortgage payments, loan amortization, VAT and tax, basic and scientific arithmetic, time calculations. These are the tools that inform the biggest financial decisions people make.

Lifestyle — Calorie and BMR calculations, cooking measurement conversions, clothing and shoe sizes across US, UK, EU and Asian standards, and fuel consumption tracking.
Finance & Business — Gross margin, markup, break-even analysis, sales and profit tracking, and monthly budget planning. Designed for entrepreneurs and small business owners.
