Visual Breakdown: Principal vs Interest
Compound Interest Calculator – Visualize Exponential Wealth Growth
Compound interest is often called the “eighth wonder of the world.” Unlike simple interest, it calculates returns on both your initial principal and the accumulated interest from previous periods. In 2026, understanding this concept is vital for anyone looking to build long-term wealth through disciplined investing.
The Mathematical Power of Compounding
The total amount accumulated depends on how often the interest is added back to the principal—whether it is daily, monthly, or annually. Our tool uses the globally recognized formula for precision:
$$A = P \left(1 + \frac{r}{n}\right)^{nt}$$
Where: A = Final Amount, P = Principal, r = Annual Interest Rate, n = Compounding frequency, t = Time in years.

❓ Compound Interest: Frequently Asked Questions
1. What exactly is Compound Interest?
Compound interest is the interest calculated on the initial principal, which also includes all of the accumulated interest from previous periods on a deposit or loan. In simple terms, it is “interest on interest.”
2. What is the difference between Daily, Monthly, and Yearly Compounding?
The frequency of compounding matters significantly. The more frequently interest is added (compounded) to the principal, the higher the final amount will be. For example, daily compounding will generate more wealth than yearly compounding for the same interest rate and tenure.
3. What is the “Rule of 72” in compounding?
The Rule of 72 is a quick financial shortcut to estimate how long it will take for your money to double at a fixed annual rate of interest. Just divide 72 by your annual interest rate. For example, at a 10% interest rate, your money will double in roughly 7.2 years.
4. How does inflation impact my compounded returns?
While compounding grows your wealth, inflation reduces the purchasing power of that money. In 2026, it is crucial to aim for a rate of return that is significantly higher than the inflation rate to ensure “Real” wealth growth.
