What is Compound Interest?
Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. Think of it as "interest on interest" – one of the most powerful ways to grow your money over time.
How We Calculate
Our calculator uses the standard compound interest formula:
A = P(1 + r/n)^(nt) + PMT × (((1 + r/n)^(nt) - 1) / (r/n))
Where:
- A = Final amount
- P = Principal (initial investment)
- r = Annual interest rate (decimal)
- n = Number of compounding periods per year
- t = Time in years
- PMT = Regular contribution amount
For inflation-adjusted values, we calculate the future purchasing power using:
Real Value = Future Value / (1 + inflation rate)^t
Tips for Better Results
- Starting earlier can significantly increase your returns due to the power of compounding.
- Regular contributions, even small ones, can drastically improve your investment growth.
- Consider the effects of inflation when planning long-term investments.
- Higher compounding frequency generally results in better returns (daily > monthly > annually).
