1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of a savings account by accounting for interest earned on both the initial principal and accumulated interest. It provides a more accurate projection of savings growth compared to simple interest calculations.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ A = P \times (1 + R / n)^{n \times T} \]

Where:

\( P \) — Principal amount (EUR)
\( R \) — Annual interest rate (decimal)
\( n \) — Compounding frequency per year
\( T \) — Time period in years
\( A \) — Maturity amount (EUR)

Explanation: The formula calculates how much your savings will grow over time with compound interest, accounting for how frequently interest is added to your account.

3. Importance of Compound Interest Calculation

Details: Understanding compound interest helps savers make informed decisions about their investments, compare different savings products, and plan for long-term financial goals in the Irish market.

4. Using the Calculator

Tips: Enter principal amount in EUR, annual interest rate as a decimal (e.g., 0.05 for 5%), compounding frequency (how many times per year interest is added), and time period in years. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

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 both the principal and accumulated interest, leading to faster growth over time.

Q2: How does compounding frequency affect savings?
A: More frequent compounding (daily vs. annually) results in higher returns because interest is added to the principal more often, allowing for interest-on-interest growth.

Q3: Are Irish savings accounts subject to taxes?
A: Yes, interest earned on savings in Ireland may be subject to Deposit Interest Retention Tax (DIRT). This calculator shows gross returns before tax deductions.

Q4: What are typical compounding frequencies in Ireland?
A: Common compounding frequencies include daily, monthly, quarterly, and annually, depending on the financial institution and account type.

Q5: Can I use this for regular savings contributions?
A: This calculator is for lump-sum investments. For regular contributions, you would need a different formula that accounts for periodic deposits.
