Discover 5 essential financial calculators for smarter planning.

1️⃣ SIP Calculator – Plan Your Investments Monthly

Investing through SIPs (Systematic Investment Plans) is a smart way to build wealth over time. But how do you know how much to invest every month to reach your goal?

That’s where the SIP Calculator shines.

✅ What it does:

  • Calculates future value of your investment
  • Helps you plan based on amount, rate of return, and duration
  • Useful for mutual funds, ELSS, or even recurring deposits

💡 Example:

You invest ₹2,000/month for 10 years at 12% expected return.
👉 Final value = ₹4.6 lakhs+

2️⃣ EMI Calculator – Understand Your Monthly Repayments

Loans aren’t bad — but not knowing your EMI is.

Whether it’s for a home, car, or personal needs, EMI calculators help you plan better and avoid surprises.

✅ What it does:

  • Gives monthly EMI
  • Shows total interest payable
  • Useful for any kind of loan

💡 Quick Tip:

A small increase in tenure can lower EMI, but increases total interest. So balance wisely.

🛠 Use the EMI Calculator to test your options.

3️⃣ Loan Eligibility Calculator – Know How Much You Can Borrow

It’s tempting to dream of a ₹50 lakh loan, but what if banks only approve ₹20 lakh based on your income?

A Loan Eligibility Calculator helps you stay realistic and plan within your range.

✅ What it does:

  • Estimates max loan based on income and expenses
  • Useful for home, personal, auto, or any bank loan

📌 Common mistake:

People assume salary alone determines eligibility — but liabilities matter too.

🛠 Use the Loan Eligibility Tool and get a ballpark figure.

4️⃣ Investment Calculator – See How Money Grows Over Time

This is a universal calculator for anyone looking to understand compound growth.

Whether you’re putting money in stocks, bonds, FD, or even crypto — this helps you visualize how much your investment can become.

✅ What it does:

  • Calculates maturity amount
  • Shows interest earned
  • Great for fixed deposits, mutual funds, or lump sum investments

💡 Example:

₹1 lakh invested for 8 years at 10% annual return = ₹2.14 lakh.

5️⃣ Home Loan Calculator – The Long-Term Planning Tool

Home loans can last 20–30 years. Even a small difference in EMI or interest rate can cost you lakhs.

A Home Loan Calculator is a must-have if you’re planning to buy property now or in future.

✅ What it does:

  • Estimates EMI
  • Shows full interest payable
  • Gives a better idea of total loan cost

⚠️ Watch out:

Don’t ignore processing fees, GST, or insurance charges — many calculators exclude them.

🛠 Use the Home Loan EMI Calculator to plan your dream home responsibly.
