1. What is the Fixed Rate Savings Formula?

The fixed rate savings formula calculates the future value of an investment based on compound interest. It's used to determine how much your savings will grow over time with a fixed interest rate and regular compounding periods.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

\[ FV = P \times (1 + r / n)^{n \times t} \]

Where:

\( FV \) — Future value (GBP)
\( P \) — Principal amount (GBP)
\( r \) — Annual interest rate (decimal)
\( n \) — Number of compounding periods per year
\( t \) — Time in years

Explanation: The formula calculates how your initial investment grows with compound interest, where interest is added to the principal at regular intervals, earning more interest in subsequent periods.

3. Importance of Compound Interest

Details: Compound interest is a powerful financial concept that allows your savings to grow exponentially over time. The more frequently interest is compounded, the faster your money grows.

4. Using the Calculator

Tips: Enter the principal amount in GBP, annual interest rate as a percentage, number of compounding periods per year, and time 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.

Q2: How does compounding frequency affect returns?
A: More frequent compounding (e.g., monthly vs. annually) results in higher returns because interest is calculated and added to the principal more often.

Q3: Are fixed rate savings accounts safe?
A: In the UK, fixed rate savings accounts offered by FSCS-protected institutions are secure up to £85,000 per person per institution.

Q4: Can I withdraw money from a fixed rate account?
A: Typically, fixed rate accounts have restrictions on withdrawals before the term ends, often with penalty fees for early access.

Q5: How is interest taxed in the UK?
A: Most UK residents have a Personal Savings Allowance (£1,000 for basic rate taxpayers, £500 for higher rate). Interest above this allowance is taxable.
