From: | To: |
Compound interest is the interest calculated on the initial principal and also on the accumulated interest of previous periods of a deposit or loan. It's often referred to as "interest on interest" and makes a sum grow at a faster rate than simple interest.
The calculator uses the compound interest formula:
Where:
Explanation: The formula calculates how much an investment will grow over time when interest is compounded at regular intervals.
Details: Understanding compound interest is crucial for financial planning, investment decisions, and loan management. It helps investors see how their money can grow over time and helps borrowers understand the true cost of borrowing.
Tips: Enter the principal amount in EUR, annual interest rate as a percentage, select compounding frequency, and time period in years. All values must be positive numbers.
Q1: What's the difference between simple and compound interest?
A: Simple interest is calculated only on the principal amount, while compound interest is calculated on the principal amount plus any accumulated interest.
Q2: How does compounding frequency affect the result?
A: The more frequently interest is compounded, the higher the final amount will be, as interest is earned on interest more often.
Q3: Is this calculator specific to the Netherlands?
A: While the formula is universal, this calculator uses EUR currency which is relevant for financial calculations in the Netherlands.
Q4: Can I use this for both investments and loans?
A: Yes, the same formula applies to both compound interest earned on investments and compound interest paid on loans.
Q5: What's the rule of 72 in compound interest?
A: The rule of 72 is a quick way to estimate how long it takes for an investment to double: Divide 72 by the annual interest rate to get the approximate number of years.
