How do I calculate simple interest?
Simple interest is calculated with the following formula: S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = The rate of interest is in percentage r% and is to be written as r/100. Principal: The principal is the amount that initially borrowed from the bank or invested.
What is the equation I PRT?
Notes: Base formula, written as I = Prt or I = P × r × t where rate r and time t should be in the same time units such as months or years. Time conversions that are based on day count of 365 days/year have 30.4167 days/month and 91.2501 days/quarter. 360 days/year have 30 days/month and 90 days/quarter.

The principal amount is Rs 10,000, the rate of interest is 10% and the number of years is six. You can calculate the simple interest as: A = 10,000 (1+0.1*6) = Rs 16,000. Interest = A – P = 16000 – 10000 = Rs 6,000.
What is interest formula?
The interest rate for a given amount on simple interest can be calculated by the following formula, Interest Rate = (Simple Interest × 100)/(Principal × Time) The interest rate for a given amount on compound interest can be calculated by the following formula, Compound Interest Rate = P (1+i) t – P.
How do you calculate simple interest?

What is the formula for simple interest?
– Calculate Principal Amount, solve for P P = A / (1 + rt) – Calculate rate of interest in decimal, solve for r r = (1/t) (A/P – 1) – Calculate rate of interest in percent R = r * 100
