| Term | Definition |
|---|---|
| Compound Interest Formula | A = P ( 1 + r) ^n or A = P ( 1 + r/n) ^n.t ( n = periods per year and t = years) |
| A = P ( 1 + r) ^n where A = | Amount (in total including the Principle and all Interest) |
| A = P ( 1 + r) ^n where P = | Principle (Initial Amount) |
| A = P ( 1 + r) ^n where r = | Rate % for the time period of n ( where 5% = 0.05) |
| A = P ( 1 + r) ^n where n = | Number of Periods (usually years) |
| Interest Earned value formula | I = A - P I value = Amount value - Principle value |
| Sub-yearly period interest rate formula | rate(sub) = rate(year) / periods per year Bi-yr = 6mths = ry / 2 ; Quarterly 3mths = ry / 4 ; Monthly = ry /12 ; Weekly= ry / 52 ; |
| Principle Required for Amount Formula | P = A / ( 1 + r) ^n |
| Number of Required Periods Formula | n = log ( A / P) ) / log ( 1 + r ) |
