The first payment is assumed to take place one full payment period after the loan was taken out, not on the first day (the origination date) of the loan. The last payment completely pays off the remainder of the loan. Often, the last payment will be a slightly different amount than all earlier payments.
An amortization calculator is used to determine the periodic payment amount due on a loan (typically a mortgage), based on the amortization process. [1]The amortization repayment model factors varying amounts of both interest and principal into every installment, though the total amount of each payment is the same.
The amount of the monthly payment at the end of month N that is applied to principal paydown equals the amount c of payment minus the amount of interest currently paid on the pre-existing unpaid principal. The latter amount, the interest component of the current payment, is the interest rate r times the amount unpaid at the end of month N–1 ...
Amortization is the acquisition cost minus the residual value of an asset, calculated in a systematic manner over an asset's useful economic life. Depreciation is a corresponding concept for tangible assets. Methodologies for allocating amortization to each accounting period are generally the same as those for depreciation.
For a coupon of 0%, where the principal amortizes linearly, the WAL is exactly half the tenor plus half a payment period, because principal is repaid in arrears (at the end of the period). So for a 30-year 0% loan, paying monthly, the WAL is 15 + 1 / 24 ≈ 15.04 {\displaystyle 15+1/24\approx 15.04} years.
The classical formula for the present value of a series of n fixed monthly payments amount x invested at a monthly interest rate i% is: = ((+))The formula may be re-arranged to determine the monthly payment x on a loan of amount P 0 taken out for a period of n months at a monthly interest rate of i%:
The total capital for a firm is the value of its equity (for a firm without outstanding warrants and options, this is the same as the company's market capitalization) plus the cost of its debt (the cost of debt should be continually updated as the cost of debt changes as a result of interest rate changes).
Capital costs are fixed, one-time expenses incurred on the purchase of land, buildings, construction, and equipment used in the production of goods or in the rendering of services. In other words, it is the total cost needed to bring a project to a commercially operable status.
