CalcMate Pro is a free collection of online calculators for the questions people ask every day: How much will I take home? How much paint do I need? How many classes can I skip? What date is 90 days from now?
What we believe
- Answers should be instant. Every calculator updates as you type.
- Math should be transparent. We show the formula behind every result and work through real examples.
- Rules change, so we update. Tax slabs, interest rates and GST rates are reviewed when governments announce changes.
- Your data is yours. Calculations happen in your browser. We don’t ask you to sign up.
Accuracy
We test each calculator against hand-worked examples and official rules. Even so, results are estimates for planning and education – your employer, bank or tax adviser has the final word. See our disclaimer.
