We use calculators every single day — to check if we can afford a loan, figure out how much to invest, understand our tax liability, or even just split a dinner bill. Yet most people still rely on basic phone calculators or complex spreadsheets. Here are 10 free online calculators on DigitCalc that every Indian should have bookmarked in 2026 — and why each one matters.
Whether you're planning a home loan, car loan, or personal loan, an EMI calculator is the first tool you should use before signing anything. Enter the loan amount, interest rate, and tenure — and instantly know your monthly outgo. This helps you decide whether the EMI fits your budget before committing.
India's mutual fund industry has grown massively — and SIPs are how millions of Indians are building long-term wealth. The SIP calculator shows you how much your monthly investment can grow over time with the power of compounding. It's an eye-opener — even ₹2,000 per month invested for 20 years can grow to over ₹20 lakhs at 12% returns.
With two tax regimes now available in India — Old and New — choosing the right one can save you thousands of rupees every year. The DigitCalc income tax calculator lets you compare both regimes instantly, factoring in your deductions under 80C, HRA, and other exemptions.
Your CTC and your in-hand salary can be very different numbers. The salary calculator breaks down your CTC into basic pay, HRA, PF, professional tax, and take-home — so you know exactly what will be credited to your bank account every month. Great for evaluating a job offer.
Fixed deposits remain one of India's most popular investment options for their safety and predictability. The FD calculator helps you find out exactly how much your deposit will grow by maturity, and how much interest you'll earn — with both simple and compound interest options.
Your Body Mass Index is a quick way to check whether your weight is in a healthy range for your height. While it's not a medical diagnosis, it's a useful starting point for health awareness. The BMI calculator on DigitCalc also shows your healthy weight range and what the result means.
Understanding how many calories your body needs each day is the foundation of any fitness plan — whether you want to lose weight, gain muscle, or simply maintain your current weight. The calorie calculator uses your age, weight, height, and activity level to give you a personalised daily target.
Sounds simple, but an age calculator is incredibly useful for government forms, exam eligibility checks, insurance applications, and more. Get your exact age in years, months, and days — useful when an application asks for age as of a specific date.
Whether you're shopping from international websites, planning a trip abroad, or sending money overseas — knowing the current INR exchange rate is essential. The DigitCalc currency converter supports 150+ currencies with live rates, so you always know exactly what you're spending.
Group dinners, shared cab rides, team lunches — splitting costs fairly is always a bit awkward. The tip and bill splitter calculates the right tip amount and divides the total among any number of people, with options for equal or proportional splits. No more mental maths or arguments at the table.
All 10 of these calculators are available for free at digitcalc.in — no login, no signup, no spam. Just open the site, run your calculation, and get on with your day. Whether you're planning a loan, checking your fitness, or splitting a dinner bill — DigitCalc has you covered.
