Formula Reference Sheet
This chapter
Simple interest
| SI | P x R x T / 100 |
|---|---|
| Amount | A = P + SI = P(1 + RT/100) |
| Rate / Time | R = 100 SI / (P T), T = 100 SI / (P R) |
Compound interest
| Amount (annual) | A = P(1 + R/100)^T |
|---|---|
| CI | A - P |
| CI - SI for 2 years | P(R/100)^2 |
| Half-yearly | rate R/2, periods 2T |
