Fast, free, and accurate calculators and tools — from feeding your pet to planning your finances.
ToolPack Pro builds simple, fast, and accurate online tools for everyday life — no sign-ups, no bloat, just honest calculators that work.
Every calculator uses established formulas — from veterinary NRC feeding standards to financial and productivity calculations.
All calculations happen in your browser. We never store, sell, or share your data. No tracking, no accounts, no nonsense.
New tools added regularly. If you need something specific, tell us — we might build it next.
ToolPack Pro is a growing collection of free online calculators and tools covering pet care, health and wellness, personal finance, cooking and baking, home improvement, productivity, and general utilities. Every tool runs entirely in your browser — your data never leaves your device, no sign-up or account required.
Whether you're a pet owner figuring out the right food portion for your dog, a freelancer calculating your true hourly rate, or a baker scaling a recipe for a different pan size, ToolPack Pro gives you fast, accurate results based on established formulas. Our pet calculators follow veterinary NRC (National Research Council) guidelines, financial tools use standard compound interest and amortization formulas, and health assessments are based on WHO metrics.
🐾 Pet Tools — Calculate exact daily feeding amounts for dogs and cats, determine how much water your pet needs daily, and convert your pet's age to human-equivalent years. All based on veterinary NRC guidelines with breed-size-adjusted formulas.
❤️ Health Tools — Track your progress with our quit smoking savings calculator, which shows how much money and lifespan you've gained since stopping. More health calculators including BMI, sleep cycles, water intake, body fat, and calorie deficit are coming soon.
💰 Finance Tools — Our freelance rate calculator helps you determine your true hourly rate after accounting for taxes, unpaid holidays, and downtime. Future tools will include compound interest projections, savings goal planners, fuel cost estimators, and tip splitters.
🍳 Cooking Tools — The recipe scaler lets you adjust any baking recipe by pan size or ingredient quantity. It includes a cup-to-gram converter with over 30 ingredient density values, fractional egg support, and sifted flour measurements.
All tools are designed to be fast, privacy-friendly, and mobile-responsive. No tracking scripts, no data collection, no bloat — just honest calculators that work.
I'm building this collection one tool at a time. If there's a calculator you need, let me know.
