The sooner you start to save, the more you'll earn with compound interest. Show
How compound interest worksCompound interest is the interest you get on:
For example, if you have a savings account, you'll earn interest on your initial savings and on the interest you've already earned. You get interest on your interest. This is different to simple interest. Simple interest is paid only on the principal at the end of the period. A term deposit usually earns simple interest. Save more with compound interestThe power of compounding helps you to save more money. The longer you save, the more interest you earn. So start as soon as you can and save regularly. You'll earn a lot more than if you try to catch up later. For example, if you put $10,000 into a savings account with 3% interest compounded monthly:
Compound interest formulaTo calculate compound interest, use the formula: A = P x (1 + r)n A = ending balance How to calculate compound interestTo calculate how much $2,000 will earn over two years at an interest rate of 5% per year, compounded monthly: 1. Divide the annual interest rate of 5% by 12 (as interest compounds monthly) = 0.0042 2. Calculate the number of time periods (n) in months you'll be earning interest for (2 years x 12 months per year) = 24 3. Use the compound interest formula A = $2,000 x (1+ 0.0042)24 Lorenzo and Sophia compare the compounding effect Lorenzo and Sophia both decide to invest $10,000 at a 5% interest rate for five years. Sophia earns interest monthly, and Lorenzo earns interest at the end of the five-year term. After five years:
Sophia and Lorenzo both started with the same amount. But Sophia gets $334 more interest than Lorenzo because of the compounding effect. Because Sophia is paid interest each month, the following month she earns interest on interest.

RD Sharma Solutions Class 8 Mathematics Solutions for Compound Interest Exercise 14.3 in Chapter 14 - Compound InterestQuestion 1 Compound Interest Exercise 14.3 On what sum will the compound interest at 5% per annum for 2 yearscompounded annually be Rs 164? Answer: Given details are,Rate = 5 % per annum Compound Interest (CI) = Rs 164 Time (t) = 2 years By using the formula, Let P be ‘x’ CI = A – P 164 = P (1 + R/100)*n – P = P [(1 + R/100)^n - 1] = x [(1 + 5/100)^2 – 1] = x [(105/100)^2 – 1] 164 = x ((1.05)^2 – 1) x = 164 / ((1.05)^2 – 1) = 164/0.1025 = Rs 1600 ∴ The required sum is Rs 1600
Video transcript hello students welcome to lido's question and answer classroom my name is shaista firozi class and today we are going to find out the sum okay so before we find out the sum let's see what the question says and the question is on what sum will the compound interest at five percent per annum for two years compounded annually b rupees 164. so that means this is clear that we need to find out the sum for the compound interest at five percent per nm so rate is five percent then time is for two years and my compound interest is rupees 164. so let's quickly jot down the details given to us so my rate is five percent for two years so that means my time period n is two years and my compound interest is rupees 160 i want to find out my sum or i can say principle so let this be p now let's quickly write down the formula for this so my formula for this is compound interest would be just hold on i'll just clear the screen so my compound interest formula as you know that it is amount minus principle so what i am going to do is i'm going to apply the formula over here in amount because i don't have an amount also and i don't have a principle also so i'll apply the formula of amount over here and i'll write down the formula instead of a that is amount so let's write down it will be compound interest is equals to now amount i don't know so i'll just write down the formula for amount which is p 1 plus r upon 100 raised to n minus p so my compound interest is 164. my principle i don't know that is supposed to be p 1 plus rate of interest is 5 raised to 2 years minus 1 okay now we have written this we will quickly change into decimal form so i'm going to change this particular part into the decimal form so let's write down this as p 1 plus 0.05 raised to 2 minus 1 becomes 164 is equals to p 1.05 raised to 2 minus 1 so 164 is equals to p into 1.05 raise to 2 minus 1 would give you 0.1025 okay so this becomes 164 upon 0.1025 is equals to p okay now just hold on i'll write down the calculation once the calculation is done so now i am going to write down my sum that is p would be after i have solved this that is after i have divided 164 by 0.1025 i will get my sum as 1600 rupees okay so this is my principle so this would be the required sum is rupees 1600 this is what the answer is okay that's all for today see you all next time till then please subscribe to lido and do comments don't forget to comment and subscribe bye bye take care On what sum will compound interest at 5% per annum for 2 years compounded annually be rupees 164?Thus, the required sum is Rs 1, 600.
What sum will the compound interest at 5% per annum for 2 years compounded annually be 1640?=Rs. 100×4×16441=Rs. 1600.
