About


Ever tried to figure out your income tax late at night with a calculator in one hand and a pile of receipts in the other? Or maybe you’ve stared at your bank’s FD rates and thought, “Wait, how do I even know which one gives me the better return?” That’s exactly the kind of moment TankCalculator.com was created for.

We know life throws all sorts of number problems at you. Some are small, like converting your GPA to CGPA for a college application. Others feel huge, like calculating the EMI on a home loan or checking how much you’ll save in a PPF account over the years. These questions don’t stop, and the truth is you shouldn’t have to be a finance expert or a math whiz just to get a straight answer.

That’s why we built TankCalculator.com: Free Online Calculators Hub. It’s a simple space where you can find tools that actually help in day-to-day life. Think of it like a Swiss Army knife of calculators. GST, FD, RD, SIP, PPF, income tax… but also student-friendly ones like GPA, SGPA, and even fun extras like astrology and numerology.

The idea is straightforward: you type in your numbers, and we do the heavy lifting in the background. No complex formulas to memorize. No guessing if you did it right. Just results you can trust.

Why Trust Us?

Because we use these tools ourselves. We’re not some faceless company tossing random code online. Every calculator on the site is tested and refined. For example, when we built our FD calculator, we checked it against actual bank data interest rates SBI, HDFC, ICICI, and others. If the math didn’t line up, we fixed it.

We also listen to feedback. A student once wrote in saying our GPA calculator didn’t fit her university’s grading system. Instead of brushing it off, we updated it to include multiple grading scales. That way, more students could get accurate results.

What Makes Tank Calculator Different?

Let’s be honest: there are already plenty of calculators floating around the internet. So why use ours? A couple reasons:

  • Clarity. Some sites throw pop ups and ads in your face before you can even hit “calculate.” We don’t.
  • Variety. Finance, academics, lifestyle we cover a wide range. It’s not just about money.
  • Updates. Tax rules change. Bank rates shift. We adjust our calculators so you’re not stuck with outdated numbers.
  • Community Input. Many of our tools came from suggestions. Someone asked for an RD calculator, another for an astrology number tool. We built both.

At the end of the day, we’re not promising to solve all of life’s problems. But if we can take away even one small headache like figuring out your EMI before applying for a loan then we’ve done our job.

So whether you’re planning your savings, double checking your GPA, or just curious about what the stars say about your name, TankCalculator.com is here. One hub. Dozens of tools. All free.
