If one looks at a home amortized loan, one would see the same effect if house values dropped. Using this example, the interest a borrower would pay on 1st September would be $1,000 ($200,000 ÷ 12 x 0.06 = $1,000). For example, assume you make mortgage payments every month. The loan amortization should be contrasted with a bullet loan, where a large portion of the loan will be paid at the final maturity date instead of being paid down gradually over the loan’s life.
The principle is, of course, the money actually borrowed. Depreciation is used for the purchase of tangible items, like a delivery truck, factory equipment or a laptop computer used for business purposes.
