## 21000$ Compound Interest Calculator

Let’s create a table for the compound interest estimation on an initial investment of $21,000 with some typical scenarios. Here are the details:

**Annual Interest Rate**: 5%**Compounding Frequency**: Annually, Semi-annually, Quarterly, and Monthly**Number of Years**: 10 years

The formula for compound interest is: A=P(1+rn)ntA = P \left(1 + \frac{r}{n}\right)^{nt}A=P(1+nrâ€‹)nt Where:

- AAA = the future value of the investment/loan, including interest
- PPP = the principal investment amount (the initial deposit or loan amount)
- rrr = the annual interest rate (decimal)
- nnn = the number of times that interest is compounded per year
- ttt = the number of years the money is invested or borrowed for

Let’s compute this for the given scenarios.

### Explanation

**Annual Compounding**: Interest is compounded once per year.**Semi-Annual Compounding**: Interest is compounded twice per year.**Quarterly Compounding**: Interest is compounded four times per year.**Monthly Compounding**: Interest is compounded twelve times per year.

The differences in future values highlight the impact of the compounding frequency. More frequent compounding results in higher future values due to interest being calculated and added to the principal more often.
