(ii) When “T’ i.e., the time is given in days then it should be divided by 365 to convert into years.

How do you solve simple interest problems?

Simple Interest Formulas and Calculations:

  1. Calculate Total Amount Accrued (Principal + Interest), solve for A. A = P(1 + rt)
  2. Calculate Principal Amount, solve for P. P = A / (1 + rt)
  3. Calculate rate of interest in decimal, solve for r. r = (1/t)(A/P – 1)
  4. Calculate rate of interest in percent. …
  5. Calculate time, solve for t.
