Formulas
Core Terms
I = (P × R × T) / 100
A = P + I
A = P + (P × R × T)/100
P = (I × 100) / (R × T)
R = (I × 100) / (P × T)
Simple Interest Problem Types
I = (P × R × T) / 100
A = P + I
Compound Interest
C.I. = A – P
A = P (1 + R/100)^n
A = P (1 + R/(2×100))^(n×2)
A = P (1 + R1/100)(1 + R2/100)(1 + R3/100) ……
