What is an Investment Calculator?
An investment calculator is an online or digital tool that helps you predict how your money will grow with investments. You enter details like:
- Initial investment amount (how much you start with)
- Monthly contributions (how much you add regularly)
- Expected rate of return (how much your investment grows each year)
- Investment period (how many years you will invest)
The calculator then shows:
- Total investment value after a certain time
- Total interest earned
- Growth over time
This helps you see if your savings plan is on track.
How Does an Investment Calculator Work?
Investment calculators use compound interest formulas to predict growth. Here’s how it works:
1. Simple Interest vs. Compound Interest
- Simple interest is calculated only on the original amount.
Example: If you invest ₹10,000 at 5% per year, you earn ₹500 yearly. - Compound interest earns interest on both the original amount and the accumulated interest.
Example: ₹10,000 at 5% compounded yearly becomes: - Year 1: ₹10,500
- Year 2: ₹11,025 (interest on ₹10,500, not just ₹10,000)
Compound interest helps money grow faster.
2. Key Inputs in an Investment Calculator
- Initial Investment – The amount you invest first.
- Regular Contributions – Extra money added monthly or yearly.
- Rate of Return – Expected yearly growth (e.g., 8% for stock market).
- Time Horizon – Number of years you stay invested.
3. Example Calculation
Let’s say you:
- Invest ₹50,000 initially
- Add ₹5,000 every month
- Expect 10% annual return
- Stay invested for 15 years
Result:
- Total invested: ₹9,50,000
- Final value: ~₹24,00,000
- Interest earned: ~₹14,50,000
This shows how small, regular investments can grow big over time.
