Even if you can’t get a 4% compound interest rate 🙂. This particular question is around GCSE grade 4 – 5 (B in old money) and deals with using the formula: Amount after n years = starting amount x (multiplier)^n. You’re asked to calculate the amount after 3 years with £4500 and a 4% compound interest rate. Calculate the interest on borrowing £40 for 3 years if the simple interest rate is 5% per year. First, work out the amount of interest for 1 year by working out 5% of £40, which is £2. The following diagram gives the Compound Interest Rate Formula where the interest is compounded once per year. Scroll down the page for more examples and solutions. Dan has £6,000 in his bank account. His bank account pays compound interest at a rate of 4% per year. Compound interest is where interest is paid on the amount already earned leading to greater and greater amounts of interest. For example £1000 at 4% compound interest would earn you £40 in the first year but in the second year you would earn 4% on the new amount of £1040 which would be £41.60. Understand how to calculate Compound Interest and pass your maths exams! Do well on your IGCSE / GCSE maths exam and let ExplainingMaths.com help you with your maths revision! Step by step, by studying example maths questions, activities and maths works To use the compound interest formula you will need figures for principal amount, annual interest rate, time factor and the number of compound periods. Once you have those, you can go through the process of calculating compound interest. The formula for compound interest, including principal sum, is: A = P (1 + r/n) (nt)

Since the interest is compounded, the yearly interest rate 'x' must be the same. The formula would be:8029.35 = 6000 * (1 + x)^5=> 8029.35/6000 = (1 + x)^55th root of 8029.35/6000 = (1 + x)=> x = 1 - 5th root See similar Maths GCSE tutors

Suppose you have a bank account containing £100. Compound interest works like this: each year, the bank calculates the interest for you based on a percentage interest rate on your account, say 3%, and adds it your total balance. In this case, 3% of 100 is 3, so your £100 would become £103.
