Estimates, not advice

CalcyZone provides free online calculators and explanatory guides for education and general planning. Every result is an estimate based on the numbers you enter and on the standard formula described on each page. Results are not financial, investment, tax, medical, legal or engineering advice, and they should not be the only basis for an important decision.

Finance and tax calculators

Loan, EMI, investment, savings and tax calculators use simplified assumptions such as a constant interest rate, a fixed contribution schedule and no fees. Real products can include processing charges, rate resets, penalties, taxes and rounding rules that change the outcome. Tax rules change every year. Confirm figures with your bank, fund house, or a qualified adviser before acting.

Health and fitness calculators

BMI, BMR, calorie, body-fat, heart-rate and pregnancy calculators are population-level screening formulas. They do not account for your full medical history and cannot diagnose any condition. Talk to a doctor or registered health professional before changing your diet, exercise or treatment, and seek urgent care for any medical emergency.

Engineering, construction and science

Material, electrical and physics calculators give textbook approximations. Building work, electrical installations and safety-critical designs must follow local codes and be checked by a qualified professional.
