About ProjectCalc

ProjectCalc is a collection of free, fast, and accurate online calculators designed to help you make better decisions — whether you are running a business, managing your personal finances, planning a construction project, or tracking your health.

We believe that complex calculations should not require expensive software or a math degree. Every tool on this site is built to be intuitive, mobile-friendly, and completely free to use.

What We Offer

• Finance Calculators — Amazon FBA profit, Etsy fees, tax brackets, 401(k) planning, CD rates, amortization schedules, and more.
• Business Tools — Profit margin, salary conversion, time tracking, and shipping cost estimators.
• Health Calculators — TDEE, macronutrient targets, sleep cycles, and calorie tracking.
• Date Tools — Quick date math for planning, deadlines, and project timelines.

Our Philosophy

No signups. No paywalls. No data tracking. Every calculator runs entirely in your browser, and your data never leaves your device.

ProjectCalc was built by a small independent team who got tired of clunky, ad-ridden calculator sites that take forever to load. We stripped away everything unnecessary and focused on what matters: accurate results, fast load times, and a clean interface.
