## Daily Compound Interest Calculator

Enter the number of days, months, and years you want to calculate compound interest for. Then enter the initial investment and the interest rate. The calculator will calculate the final amount after the specified time period.

## How to use the calculator

Enter the number of days, months, and years you want to calculate compound interest for. Then enter the initial investment and the interest rate. The calculator will calculate the final amount after the specified time period.

For example, if you want to calculate the amount you will have after 10 days, enter 10 for the number of days. Then enter the initial investment and the interest rate. The calculator will calculate the final amount after 10 days.

If you want to exclude weekends from the calculation, check the "Exclude weekends" checkbox. The calculator will calculate the final amount after 10 days, excluding weekends.

## How to calculate compound interest

Compound interest is the interest you earn on your initial investment, plus the interest you earn on the interest you earn on your initial investment, plus the interest you earn on the interest you earn on the interest you earn on your initial investment, and so on...

For example, if you invest $1000 at 10% interest, you will earn $100 in interest. If you invest that $100 in another investment at 10% interest, you will earn $10 in interest. If you invest that $10 in another investment at 10% interest, you will earn $1 in interest. You will earn $111 in interest in total.

To calculate the final amount after a specified time period, you multiply the initial investment by (1 + interest rate) to the power of the number of days. For example, if you invest $1000 at 10% interest for 10 days, the final amount will be: ${\$1000\times(1+0.1)^{10} = \$2,593.74}$.

To calculate the increase in amount, you subtract the initial investment from the final amount. For example, if you invest $1000 at 10% interest for 10 days, the increase in value will be: ${\$2,593.74-\$1000 = \$1,593.74}$.

To calculate the percentage of the increase in value, you divide the increase in amount by the initial investment and multiply the result by 100. For example, if you invest $1000 at 10% interest for 10 days, the percentage of the increase in value will be ${\frac{\$1,593.74}{\$1000} \times 100 = 159.37\%}$.

## How to calculate compound interest without a calculator

To calculate the final amount without a calculator, you can use the following formula: ${FV = PV\times(1+D_i)^{t_i}}$

Where:

- ${FV = Final\ \ Value}$
- ${PV = Principal\ \ Value}$
- ${D_i = Daily\ \ Inerest\ \ Rate}$
- ${t_i = The\ Number\ of\ Days\ of \ Re-Investment}$
- ${\Delta V = The\ Change\ in\ Value}$

For example, if you invest $1000 at 10% interest for 10 days, the final amount will be: ${\$1000\times(1+0.1)^{10} = \$2,593.74}$.

To calculate the increase in value of the principal without a calculator, you can use the following formula: ${\Delta V = FV - PV}$

For example, if you invest $1000 at 10% interest for 10 days, the increase in percentage will be ${\$2,593.74-\$1000 = \$1,593.74}$.

To calculate the increase in percentage without a calculator, you can use the following formula: ${\Delta V \% = \frac{\Delta V}{PV} \times 100}$

For example, if you invest $1000 at 10% interest for 10 days, the increase in amount will be ${\frac{\$1,593.74}{\$1000} \times 100 = 159.37\%}$.
