Frequently asked questions
- What is Practical Tools?
- Practical Tools is a free collection of online calculators, generators, and converters built for small business owners, freelancers, property investors, and anyone who needs fast, accurate answers to everyday financial and business questions. Every tool is free, no account required.
- Are these tools really free?
- Yes. Every tool on this site is completely free to use - no trial period, no premium tier, no credit card required. The site is supported by minimal, non-intrusive advertising (not yet live) and runs on static hosting, which keeps costs low.
- Is my data private?
- Yes. All calculations run entirely in your browser. No data you enter into any tool is ever sent to a server, stored in a database, or shared with anyone. You can use the tools to calculate sensitive financial figures without any privacy concern.
- Do I need to create an account?
- No. There are no accounts, no logins, and no signups anywhere on this site. Open any tool and start using it immediately.
- Who are these tools for?
- The tools are built for small business owners, freelancers, property investors, landlords, Airbnb hosts, house flippers, e-commerce sellers, and anyone making financial, pricing, or everyday decisions who wants a fast, accurate number without opening a spreadsheet.
- How accurate are the calculators?
- Each calculator uses the correct underlying formula for its calculation - for example, the standard amortisation formula for loan payments, GS1's alternating-weight algorithm for barcode check digits, and year-by-year compound growth for the rent vs buy comparison. Results are mathematically correct for the inputs you provide. Where results are estimates (property valuations, renovation returns, Airbnb occupancy), the tool notes this clearly and includes a disclaimer.
