How we worked it out

Updated as you change the numbers.

  1. I = P × r × t = $5,000.00 × 0.06 × 3 years = $900.00.

Method and assumptions

Simple interest is principal × annual rate × time in years. Months are divided by 12 and days by 365; some lenders use a 360-day year, which gives slightly more interest.
