Why this exists

Most free tool sites are cluttered, slow, and try to upsell you. FreeToolyard.com is different — a growing set of genuinely useful calculators and generators that run entirely in your browser, save no data, and never ask you to sign up.

Each tool here solves a specific question we kept Googling and getting bad answers to. The kind of stuff a friend who's good at spreadsheets would help you with in 5 minutes.

If a tool here saves you ten minutes, that's the win. If it saves you from making a bad financial decision, even better.

💼 Freelance & pricing

What should you actually charge?

Most freelancers undercharge because they only count days they want to work. Real freelancing has sick days, slow weeks, admin and marketing. This calculates a sustainable rate based on reality — with proper tax handling for your country.

💸 Personal finance

What are you really spending on subscriptions?

Most people underestimate by 2–3x. Add yours below and see the annual damage. Includes the 5-year compounded cost — what those subs really cost over time if you'd invested instead.

Your subscriptions
Common ones to check: Netflix, Spotify, Disney+, Apple TV+, Amazon Prime, gym, cloud storage (iCloud, Google One, Dropbox), news subscriptions, fitness apps, dating apps, software (Adobe, Notion, etc.), mobile data plans, charity recurring donations.

💰
The "if invested" line is the real one. Money spent on subscriptions is money that's not compounding. $50/month into a low-cost index fund for 5 years at 7% returns isn't $3,000 — it's roughly $3,580. The opportunity cost is bigger than the subscriptions themselves.

🧳 Travel & budgeting

Generic "trip budget" advice is useless because Tokyo and Hanoi aren't the same trip. Pick your destination tier, travel style, and trip length for a realistic daily and total estimate.

🎬 Creator economy

What you actually take home.

Platform cut, payment processing, and tax. The gap between gross revenue and what hits your bank is bigger than most creators realise. Calculations adjusted for your country's tax rules.

⚠️
Tax is the killer. Set aside the tax estimate every month or you'll owe a scary number at year end. Treat creator income like contractor income: the platform won't withhold tax for you. Talk to an accountant once you cross $20k/year of revenue — they'll save you more than they cost.

🌙 Health & sleep

Wake between cycles, not in the middle of one.

A sleep cycle is roughly 90 minutes. Wake at the end of one and you feel rested; wake mid-cycle and you feel awful. This works backwards from your wake time to give you the best bedtimes — including a shift-worker mode for nurses, pilots, and night owls.

Save this for daily use. Press Ctrl+D (or ⌘+D on Mac) to bookmark.
When do you need to be up?
Best times
😴
Shift-worker tips: Block all daylight (blackout curtains + sleep mask), keep room cool (18–20°C), use white noise to mask daytime sounds. Aim for the longer 6-cycle (9-hour) sleep when possible — daytime sleep is less restorative per hour than night sleep.

🐕 Pet health

How much should your dog actually eat?

Vet-formula based (Resting Energy Requirement × activity factor). The result tells you your dog's daily calories — match that against your dog food's label kcal/cup or kcal/can.

Heads up: This is an estimate based on standard veterinary formulas. Some breeds (toy breeds, Northern breeds, sighthounds) have metabolisms that differ. If your dog is gaining or losing weight unexpectedly, see your vet — don't just adjust portions on your own.

Take-home is estimated. Actual tax depends on your exact deductions, offsets, and local rules. AU includes Medicare + super offset. US uses federal tax only — state tax varies 0–13%. UK includes NI. These numbers are a solid guide, not a tax return.

Tip: Real-world fuel use is typically 10–20% higher than manufacturer specs due to air conditioning, hills, luggage load, and driving style. If you're planning a long trip, add a 10% buffer to be safe. Also factor in rest stop top-ups if your tank is small.

Reading speed research: The 238 wpm average comes from Brysbaert's 2019 meta-analysis of 190 studies with 17,000+ participants. Individual rates vary widely — college-educated adults typically read 250–300 wpm. For a presentation with pauses and slide transitions, add 15–20% to the speaking time estimate.

Mental maths shortcut: To find 20% off any price, just divide by 5. To find 25% off, divide by 4. To find 10% off, drop the last digit. A $148 item at 20% off = $148 ÷ 5 = $29.60 saving, so you pay $118.40.
