About GM¹X CalcVerse
Free calculators that show their working, built by GM¹X, a GeekMidst product line.
CalcVerse is a library of free online calculators for money, maths, business, health, education, dates and measurement. It is part of GM¹X, the product family from GeekMidst.
What makes these calculators different
- Every result shows its working. Each calculator page states the formula, defines every variable and walks through a worked example.
- Calculations are tested before they are published. The calculation code must reproduce independently derived reference values, and the numbers in each worked example are recomputed by the live calculator in our automated tests.
- Your numbers stay on your device. Calculations run in your web browser. What you type into a calculator is not sent to our servers.
- Rules set by authorities are dated. Where a result depends on a government rate, such as India’s GST, the page shows the jurisdiction, the date the rates took effect and the source.
What CalcVerse is not
CalcVerse gives estimates to help you plan and check numbers. It is not financial, tax, legal or medical advice. For decisions that matter, check the result with a qualified professional.
Calculators for your business
GM¹X also builds branded calculators that businesses can embed in their own websites. Details will be published here when the service opens.
