We're committed to maintaining this free access model so that anyone, anywhere can benefit from our calculation tools regardless of their financial situation.
How accurate are the calculators?
Each calculator applies a published, standard formula — the Mifflin-St Jeor equation for calorie needs, the amortisation formula for loan payments, sqrt(1 + (rise/12)²) for roof pitch multipliers, and so on — and most show their working so you can check the arithmetic yourself. Where the maths is pinned down exactly, we test it against independently derived values.
Correct arithmetic is not the same as being right for your situation. Results depend entirely on the figures you enter, and these tools do not know your medical history, your finances, your local building codes, or your site conditions. Treat the output as a starting estimate rather than a professional opinion, and consult a qualified professional before any decision with significant financial, health, or safety consequences.
Can I suggest a new calculator?
Absolutely! We're always looking to expand our collection of calculators. Visit our Suggestions page to submit your ideas for new calculators or improvements to existing ones.
