About the Founder
EzyCalc is created and maintained by Mohammad Rijwan, an I.T. Manager with 7 years of experience in the information technology field. Working with software, systems and data every day showed him how often people need quick, trustworthy calculators and how few websites explain the method behind the result.
He builds and reviews every tool on EzyCalc with a focus on accuracy, speed, privacy and a clean experience on every device. You can reach him anytime through the Contact page.
How Our Calculators Work
Every calculator on EzyCalc uses standard, publicly known formulas — for example, the reducing-balance EMI formula for loans, the weight-divided-by-height-squared formula for BMI, and the standard percentage formulas for marks and discounts. All calculations run directly in your browser using JavaScript, so the numbers you enter are not sent to our servers or stored.
Each tool page includes the formula used, worked examples and answers to common questions, so you can understand the result and not just see a number.
Why We Built EzyCalc
Many calculator websites are cluttered, slow, or hide the method behind the result. EzyCalc was created to offer clean, fast and accurate tools for everyday needs — students checking exam percentages, families planning loans, employees working out gratuity or ESI, and anyone who needs a quick answer. We focus especially on calculators relevant to Indian users, such as GST, ICSE/ISC percentage, gratuity and ESI.
Accuracy and Updates
We review our calculators and their explanations regularly and update them when rules, rates or formulas change. Results are meant for general information and planning. For legal, tax, medical or financial decisions, please confirm with a qualified professional or the official source. If you spot an error, please tell us through the Contact page and we will fix it promptly.
How We Research and Write Our Content
Every calculator and guide on EzyCalc starts from the official rule or a standard formula, not from another website’s summary. For tax, labour, banking and education topics we check the primary source: the GST Council and GST portal, the Ministry of Labour and Employment, the Reserve Bank of India, the Income Tax Department and CISCE. The sources are linked at the bottom of each guide.
Each guide includes a worked example with the inputs shown, so you can repeat it on the matching calculator and get the same answer. Where a rule is interpreted differently by different employers or institutions, for example the “4 years 240 days” gratuity question, we say so, and we do not present a common interpretation as a guarantee.
You can read the current set on the Guides page.
Corrections and Updates
Rates, limits and rules change. When they do, we update the calculator and the related guide together and change the “last updated” date shown on the page. Guides currently reflect the rules as of 13 October 2026.
If you find a mistake, please tell us what the page says, what you believe is correct and, if possible, the official source. Write to hello@ezycalc.fun or use the Contact page. We check every report and fix confirmed errors.
EzyCalc is an information tool. Results are estimates for planning and are not legal, tax, medical or financial advice. For decisions that matter, confirm with the official source or a qualified professional.
