Use Calculator Formula and Mathematical Explanation
The mathematical foundation of the Use Calculator relies on the standard amortization formula. This formula calculates the fixed monthly payment required to pay off a loan over a specific period at a fixed interest rate.
The formula used by the Use Calculator is:
M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| M | Total Monthly Payment | Currency ($) | $500 – $5,000+ |
| P | Principal Loan Amount | Currency ($) | $100,000 – $2,000,000 |
| i | Monthly Interest Rate | Decimal | 0.002 – 0.008 |
| n | Number of Months | Integer | 120 – 360 |
