The Use Calculator employs the standard amortization formula to determine the fixed monthly payment required to pay off a loan over a specific period. The formula used by the Use Calculator is:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
Where:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| M | Total Monthly Payment | Currency ($) | Varies |
| P | Principal Loan Amount | Currency ($) | $1,000 – $1,000,000+ |
| i | Monthly Interest Rate | Decimal | Annual Rate / 12 / 100 |
| n | Number of Months | Integer | 12 – 360 months |
