How do you calculate principal and interest?
Simple Interest Formulas and Calculations:
- Calculate Total Amount Accrued (Principal + Interest), solve for A. A = P(1 + rt)
- 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.
- Calculate time, solve for t.
