# CalcGate

> CalcGate (https://calcgate.com) is a free, global online calculator and educational content platform. We offer 100+ interactive calculators for finance, loans, tax, health, education, math, and everyday use — plus 60+ in-depth blog guides. No signup required; calculations run locally in the browser for privacy.

## What CalcGate is

CalcGate helps people worldwide make quick, informed decisions with accurate calculator tools and plain-language guides. The product has two layers:

1. **Global catalogue** — Universal tools (BMI, EMI, SIP, mortgage math, percentage, unit converters, etc.) that work the same for users in any country.
2. **Regional depth** — Country-specific calculators where tax law or regulation differs: UK take-home pay and stamp duty, US tax and retirement tools, India GST/PPF/NPS, EU hubs, and more at `/uk`, `/us`, `/eu`, `/in`.

Finance and tax pages cite official government sources (HMRC, IRS, CBDT, etc.) where applicable. Content is for estimation only — not financial, tax, or legal advice.

## Primary audiences

- Anyone searching for a free online calculator (global)
- UK, US, EU, and India users who need jurisdiction-specific tax or payroll tools
- Readers looking for calculator explainers linked to live tools
