Use Calculator Formula and Mathematical Explanation
The math behind the Use Calculator relies on the standard amortization formula. This formula calculates the fixed monthly payment required to pay off the principal and interest over a specific term.
The Formula: M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| M | Monthly Payment | Currency ($) | Varies |
| P | Principal Amount | Currency ($) | $1,000 – $1,000,000+ |
| i | Monthly Interest Rate | Decimal | 0.001 – 0.02 |
| n | Number of Months | Count | 12 – 360 |
