What is the Time Value Concept in Loan Amortization?
The time value concept in loan amortization refers to how each payment’s principal/interest ratio changes over the life of a loan. This calculator demonstrates how earlier payments contain more interest while later payments apply more to principal.
Amortization Formula Explained
The monthly payment is calculated using:
M = P[r(1+r)^n]/[(1+r)^n-1]
| Variable | Meaning | Unit | Range |
|---|---|---|---|
| P | Principal | $ | $1k-$5M |
| r | Monthly rate | % | 0.1%-25% |
| n | Total payments | Months | 12-480 |
