Compound Interest Formula:
From: | To: |
The compound interest formula calculates the future value of an investment based on the principal amount, interest rate, compounding frequency, and time period. It demonstrates how investments grow exponentially over time through the power of compounding.
The calculator uses the compound interest formula:
Where:
Explanation: The formula calculates how an initial investment grows when interest is earned on both the principal and accumulated interest over multiple compounding periods.
Details: Understanding compound interest is essential for investment planning, retirement savings, and making informed financial decisions. It helps investors project future returns and compare different investment options.
Tips: Enter principal amount in GBP, annual interest rate as a decimal (e.g., 0.05 for 5%), compounding frequency (how many times per year interest is compounded), and time period in years. All values must be positive numbers.
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 exponential growth.
Q2: How does compounding frequency affect returns?
A: More frequent compounding (daily vs. annually) results in higher returns due to interest being calculated and added to the principal more often.
Q3: What is a typical compounding frequency for Nutmeg investments?
A: Nutgem typically compounds interest daily or monthly, depending on the specific investment product.
Q4: Can this calculator be used for other currencies?
A: While designed for GBP, the formula works for any currency as long as consistent currency units are used throughout the calculation.
Q5: How accurate are the calculator's projections?
A: The calculator provides mathematical projections based on constant interest rates. Actual investment returns may vary due to market fluctuations and changing interest rates.
