How to use this Compound Interest Calculator?

Here is what the terms mean:

Principal Amount (P)

In this box, you have to enter the initial amount of money you started with. For example, if you had invested or want to invest $1,000, that’s your principal amount.

2. Interest Rate per Period (r)

In this box, you’ll enter the percentage rate that your investment will earn over time. For example, if your interest rate is 5%, you’d simply type in 5.

3. Duration

This is where you enter how long you plan to keep your money invested. You can choose to enter the time in either years or days, depending on what makes sense for your investment plan.

For instance, if you want to calculate compound interest for just a few days, you will enter the number of days.

4. Time Unit: Days or Years?

Here, you can select whether you want to enter your duration in years or days. Just pick the option that fits how you think about your investment.

5. Compounding Frequency

This is about how often the interest gets added to your principal. Do you want it to compound daily, weekly, monthly, quarterly, or maybe just yearly? Choose the frequency that applies to your situation.

6. Currency

Select the currency you’d like to see your final amount in. Whether it’s USD, EUR, GBP, or another currency, just choose the one that works best for you.

7. Calculate Button

Once you’ve filled in all the information, click the Calculate button to see your final result. The calculator will then do the math and show you how much your investment will grow over the time period you specified.

8. Result

Once the calculation is done, the Final Amount will appear below the button, showing you the total amount (including interest) in your selected currency. This is the amount you’ll have after compounding your principal at the set interest rate.
