If there's a calculator you'd find useful that we don't have yet, we want to hear about it. Our roadmap is driven almost entirely by user suggestions.
How to suggest
Email contact@alltoolscalculator.com with as much of the following as you can:
- Name — what this calculator would be called
- Category — which existing category it fits, or if it needs a new one
- Inputs and output — what you'd enter, what you'd get back
- Formula or source — if you know the math, or have a reference link
- Example — a similar tool on another site, if one exists
What we prioritise
We tend to build tools that have:
- A well-defined, verifiable formula (so we know the answer is right)
- Broad utility — many people have the same question
- No existing good free option — or existing options are ad-choked and slow
What's already on the roadmap
Tools we plan to add soon:
- Rent-vs-buy calculator (Real Estate)
- Retirement projection (Finance)
- Freelancer hourly-rate calculator (Business)
- Unit converters — length, weight, volume, temperature (Conversions)
- Currency converter with live rates (Conversions)
- Time zone converter (Conversions)
- Date difference calculator (Tax & Date)
If your suggestion is on this list, adding your voice helps us decide what to build first.
What we won't build
We skip calculators that:
- Would provide medical diagnosis or dosing recommendations
- Require proprietary data we can't ethically source
- Are so niche that a spreadsheet serves better
