What to Focus On

  • Principal (P) = Original sum of money
  • Rate (R) = Percentage of interest per annum
  • Time (T) = Duration in years

  • SI = (P × R × T) / 100
  • Amount = P + SI = P(1 + RT/100)
  • Annual interest remains constant

  • CI = P[(1 + R/100)^T - 1]
  • Amount = P(1 + R/100)^T
  • Interest compounds (earns interest on interest)

Common Mistakes to Avoid

In compound interest, if the rate is compounded half-yearly, I simply use half the rate for double the time period without any other adjustments

Simple Interest and Compound Interest are the same for the first year, so their difference formula CI - SI = P(r/100)^2 works for any time period

When money doubles in 'n' years at simple interest, the rate is always 100/n percent
