🤔 How Does This Tool Work?

The Savings Calculator uses compound interest mathematics to show how your savings grow over time:

Formula: Total = Initial × (1 + r)ⁿ + Monthly × ((1 + r)ⁿ − 1) ÷ r

Where:

  • r = monthly interest rate (annual rate ÷ 12 ÷ 100)
  • n = total months (years × 12)

The calculator shows your total savings, how much you personally contributed (initial + monthly deposits), and how much came from interest — so you can see the amazing power of compound growth!

❓ FAQ
How much should I save every month?▼
Financial experts generally recommend saving at least 20% of your income. But any amount is better than nothing — the habit of saving matters more than the amount when you first start.
Does it matter if I start saving later?▼
Enormously! Compound interest means that starting even 5 years earlier can result in tens of thousands more in your final savings. The earlier you start, the more time your money has to grow.
What interest rate should I use for my calculation?▼
Use the actual interest rate your savings account or fixed deposit pays. In Sri Lanka, fixed deposit rates have ranged from 8% to 15% in recent years. Check with your bank for current rates.
Can I use this for investment calculations?▼
Yes! You can use it to estimate investment growth, but remember that investments (unlike savings accounts) can go up AND down. This calculator shows steady growth — actual investment returns vary.
What if I can only save a small amount each month?▼
Even small amounts add up dramatically over time thanks to compound interest. Use our calculator to see — you might be surprised how much even 1,000 rupees per month grows over 10 or 20 years!
