Investment Calculator: Plan Your Financial Future with Precision
Our free investment calculator helps you forecast the growth of your investments with compound interest, whether you're saving for retirement, education, or other long-term goals. This powerful tool calculates:
- Future value of lump sum investments
- Projected growth with regular contributions
- Compound interest earnings over time

How Compound Interest Works
Compound interest is the eighth wonder of the world (according to Einstein) because it allows your money to grow exponentially. Unlike simple interest, compound interest earns returns on both your principal and accumulated interest. Our calculator shows exactly how small, regular investments can grow significantly over 10, 20, or 30 years.
