1. What is the Compound Interest Formula?

The compound interest formula calculates the future value of an investment or savings account based on the principal amount, annual interest rate, compounding frequency, and time period. It demonstrates how money can grow over time through the power of compounding.

2. How Does the Calculator Work?

The calculator uses the compound interest formula:

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

Where:

\( FV \) — Future Value (GBP)
\( P \) — Principal amount (GBP)
\( r \) — Annual interest rate (decimal)
\( n \) — Compounding periods per year
\( t \) — Time in years

Explanation: The formula calculates how much your savings will grow based on the interest rate and how frequently that interest is compounded.

3. Importance of Saving Rates Comparison

Details: Comparing saving rates across different UK banks is crucial for maximizing returns on your savings. Even small differences in interest rates can lead to significant variations in long-term savings growth.

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, leading to faster growth.

Q2: How often do UK banks typically compound interest?
A: Most UK savings accounts compound interest monthly or annually, but this can vary by bank and account type.

Q3: Are savings account interest rates fixed or variable?
A: Both options exist. Fixed-rate accounts offer guaranteed rates for a set period, while variable rates can change with the Bank of England base rate.

Q4: What factors should I consider when comparing UK saving rates?
A: Consider the interest rate, compounding frequency, account fees, accessibility of funds, and whether the rate is fixed or variable.

Q5: Is compound interest taxable in the UK?
A: Interest earned on savings may be subject to tax, but most UK residents have a Personal Savings Allowance that allows them to earn some interest tax-free.
