What is an amortizing payment?

An amortizing payment is a periodic payment on a loan that consists of both principal (which reduces the outstanding balance) and interest (the fee for borrowing). Early payments consist mostly of interest, while later payments consist mostly of principal reduction.

How does payment frequency affect loan interest?

Making more frequent payments (e.g., bi-weekly or weekly instead of monthly) reduces the principal balance faster, resulting in less interest compounding over time. This can shave years off a loan term and save thousands of dollars.

Payment Equations Explained

The periodic payment is derived from standard financial annuities. The math changes depending on whether you are paying down a debt or accumulating a savings goal:

1. Loan Repayment Formula

Amortizing loan payments are solved using:

M = P × [ r(1+r)^N ] / [ (1+r)^N - 1 ]

where $P$ is principal, $r$ is rate per period, and $N$ is total periods.

2. Savings Accumulation (Annuity) Formula

Required periodic savings deposits to hit a future target $FV$ are solved using:

PMT = FV × r / [ (1+r)^N - 1 ]
