About Global Compound Interest Calculator
This advanced compound interest calculator helps you estimate the future value of your investments with inflation adjustment. It supports multiple currencies and compounding frequencies to provide accurate global projections.
Purpose of the Tool
This calculator is designed to:
- Help investors understand the power of compound interest across different currencies
- Show the real (inflation-adjusted) value of future investments
- Compare different compounding frequencies (annual, monthly, daily)
- Plan long-term investments with regular contributions
- Understand how inflation erodes purchasing power over time
- Make informed decisions about savings and investment strategies
Real-world Examples
Example 1: $10,000 invested at 7% return for 30 years with monthly compounding grows to $81,170 nominally. With 2.5% inflation, the real value is $38,697 in today's dollars.
Example 2: ₹50,000 invested with ₹5,000 annual additions at 12% return for 20 years grows to ₹54.3 lakhs nominally. With 6% inflation, the real value is ₹16.9 lakhs in today's rupees.
Example 3: €20,000 at 5% return with quarterly compounding for 15 years becomes €41,578. With 2% inflation, the purchasing power equals €30,923 today.
Formulas and Algorithms
The calculator uses the following mathematical formulas:
1. Compound Interest Formula:
FV = P × (1 + r/n)^(n×t) + PMT × [((1 + r/n)^(n×t) - 1) / (r/n)]
Where:
FV = Future Value
P = Principal investment amount
r = Annual interest rate (decimal)
n = Number of compounding periods per year
t = Time in years
PMT = Annual addition
2. Inflation Adjustment:
Real Value = Nominal Value / (1 + inflation)^t
Purchasing Power = Nominal Value × (1 + inflation)^-t
3. Effective Annual Rate:
EAR = (1 + r/n)^n - 1

Frequently Asked Questions
Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. It causes wealth to grow exponentially over time.
Inflation reduces purchasing power over time. $100 today buys more than $100 in 10 years. Inflation adjustment shows the real value of future money in today's terms.
Yes, more frequent compounding (monthly vs annually) yields higher returns because interest is calculated on accumulated interest more often.
Historical averages: 7-10% for stocks, 3-5% for bonds. Adjust based on your investment mix and risk tolerance.
Use long-term averages (2-3% for developed countries, 4-6% for developing) or recent trends. In India, 6% is often used for conservative estimates.
Yes, just set annual addition to zero to calculate compound interest on a lump sum investment only.
Different currencies have different inflation rates and investment opportunities. This calculator helps compare scenarios globally.
These are mathematical estimates. Actual returns vary due to market fluctuations, taxes, fees, and changing economic conditions.
