Simple Interest is calculated using the following formula: SI = P × R × T, where P = Principal, R = Rate of Interest, and T = Time period. Here, the rate is given in percentage (r%) is written as r/100.
What formula is used for simple interest problems?
Examples of finding the interest earned with the simple interest formula
- In many simple interest problems, you will be finding the total interest earned over a set period, which is represented as I.
- Let’s use an example to see how this formula works.
- I=Prt=500(0.04)(2)=40.
- t=412=13.
- I=Prt=1200(0.06)(13)=24.
How do you calculate interest rate word problems?
