About SolveCalcPro

Last updated September 26, 2026

SolveCalcPro is a free scientific calculator and a growing set of math tools for students, teachers, parents and anyone who needs a quick, correct answer. Everything runs in your browser: there is no account, no download and no upload of your numbers.

You may see it typed in different ways: SolveCalcPro, Solve Calc Pro, CalcSolve Pro or SolverCalc Pro. They all mean this site. It is an independent project and is not affiliated with other websites that use similar names. New to calc solvers? Read what a calc solver is.

What we offer

• A scientific calculator with trigonometry, logarithms, roots, powers, factorials, memory, history and a Code Mode for typing expressions like sin(30)+2^3.
• Math tools for percentages, fractions, quadratic equations, GCF and LCM, prime numbers, number bases, statistics, the Pythagorean theorem, and everyday finance such as mortgage and compound-interest estimates.
• Worked explanations beside each tool, so you can see the formula and the steps and not only the final number.

How we keep results accurate

The calculator uses its own expression parser (it never runs arbitrary code), and every tool's formulas are documented on its page. We test the calculation engine with automated tests and re-check tools against hand-worked examples. Read our editorial policy to see how we handle corrections.

Who runs the site

SolveCalcPro is operated by Hindustan Prime, a partnership firm registered in India (Village Mawaiya, Chakiya, Chandauli, Uttar Pradesh — 232102). Reach us any time on the contact page.

How the site is funded

SolveCalcPro is free to use and supported by advertising. Ads are labelled and kept separate from tools and explanations, and they never change a result.

What we are not

We are not a tax preparer, lender, financial adviser or teacher of record. Financial tools give estimates for planning only. See the disclaimer.
