Understanding Interest Rates with Percentages

1. How to Calculate Interest Rates Using Percentages

Interest rates are expressed as percentages. For example, if you invest €1,000 at an annual interest rate of 5%, you earn €50 in a year. The formula is simple: Interest = Principal × Rate × Time.

2. Understanding Compound Interest

Compound interest adds interest on both the initial amount and accumulated interest. Over time, this significantly boosts savings. For instance, €1,000 at 5% compounded yearly becomes €1,276.28 in five years.

3. Interest Rates and Loan Costs

Borrowing money? That 12% APR on your credit card means you pay 12% of your balance yearly in interest unless paid off. Use percentages to compare loan offers and understand true costs.

4. Calculating Returns on Savings

Want to know how much your savings will grow? A percentage-based return calculation helps. For example, 3% annual return on €5,000 earns you €150 per year. Adjust for monthly compounding if applicable.
