Building The Apex Calc: A Fast, Ad-Free Financial & Amortization Utility

Most online financial calculators are buried under invasive display ads, auto-playing video popups, and slow third-party analytics trackers. Trying to compute a mortgage amortization schedule or evaluate a wage increase shouldn't feel like navigating an obstacle course.

To fix this, I built The Apex Calcβ€”a privacy-focused, zero-bloat financial computation suite.

What it covers:

  • Mortgage Payment & Amortization: Calculates monthly principal, interest, taxes, and schedule projections.
  • Hourly-to-Salary Wage Converter: Real-time breakdown across weekly, monthly, and annual compensation with overtime adjustments.
  • Compound Interest Modeling: Visualizing long-term wealth accumulation with periodic contributions.

Technical Highlights:

  • 100% Client-Side: Written in vanilla JavaScript, HTML5, and clean CSS. Zero server roundtrips for computation.
  • Zero Tracking: No tracking pixels or external data collection. Sensitive monetary calculations stay local in the browser.
  • Speed & Privacy: Fast initial paint and sub-second execution across both mobile and desktop.

Would love to get feedback on the UI layout and what calculator models you'd like to see added next!
