Explanation: The formula shows how your savings grow exponentially over time, with more frequent compounding (higher n values) resulting in greater returns.
Details: Understanding compound interest is crucial for effective financial planning. It helps savers maximize returns by choosing accounts with the best interest rates and most favorable compounding frequencies available in the UK savings market.
Tips: Enter principal amount in GBP, annual interest rate as a decimal (e.g., 0.05 for 5%), number of compounding periods per year, and time in years. All values must be positive numbers.
Q1: What are the best interest rates currently available in the UK?
A: Interest rates vary by institution and account type. Check comparison websites regularly for current best rates on savings accounts, ISAs, and fixed-term deposits.
Q2: How often do savings accounts typically compound interest?
A: Most UK savings accounts compound interest annually, though some offer monthly, quarterly, or daily compounding. More frequent compounding generally yields higher returns.
Q3: Are there tax implications for savings interest in the UK?
