Building CalcNest: A Free, Privacy-Focused Financial Calculator Suite for India & USA

When dealing with daily financial calculations—like planning mutual fund SIPs, estimating loan EMIs, or figuring out the take-home salary after taxes—most online tools are cluttered with intrusive ads, paywalls, or forced login popups.

To solve this, I built CalcNest: a clean, client-side financial computation suite designed with both Indian and US fiscal models in mind.

🌟 Core Utilities Built:

  • SIP & Step-Up Calculator: Accurately models compound growth milestones for equity investments.
  • Loan EMI Calculator: Visualizes amortized debt schedules and principal vs interest components.
  • Salary & In-Hand Estimator: Breaks down gross CTC into monthly take-home pay with deductions.
  • New vs Old Tax Regime Analyzer: Compares tax liabilities based on the latest regional slabs.
  • Everyday Math & Health Utilities: Instant GST/Sales tax, BMI, and percentage change computations.

🔒 100% Privacy by Design

Every computation runs locally in your web browser via optimized JavaScript. No inputs are stored or transmitted to external servers.
