Lightweight tools, accurate results

Why this exists

Finance calculators are scattered, ad-heavy, mobile-broken, ignore real tax rules, or have no way to share results. trovetool exists to solve all of that in one place.

Operating principles

• **Light** — every tool works on 320px mobile.
• **Accurate** — real tax rules (2026 401(k) limits, federal brackets, FICA) and inflation baked in.
• **Safe** — input never leaves the browser. All math runs client-side.
• **Persistent** — at least one new tool per month, and existing tools stay maintained.
