To make it a little simplified, an amortization schedule is just a payment made towards a loan hitting both the interest that was compounded together with the principal amount and balance that exists. The amortization schedule tries to tangibly present the amount that is being placed to cover the interest and the amount pressed against the principal loaned amount. It usually works by scheduling to put much bulk on the payment of the interest and as the loan is reaching its maturity, huge portions of the amount that is being paid go towards the principal loaned amount. To put it very short and brief, with amortization schedule, you pay first the calculated interest at the beginning of the payment date while the principal loaned amount is going to be settled on the latter part of the payment date as created by the amortization schedule.
As it suggests, the amortization schedule should follow a specific order of payment. Otherwise, if not taken in that context, it defeats the entire purpose of it. Naturally, the initial payment on the loan is expected to be taking place after the loan was granted to be released. Apart from the fact the amortization schedule's revelation of the payment made on the interest and principal, the amortization schedule allows also the revelation of the interest that was already paid on the date that it was posted, the principal paid to date, and the remaining principal balance on each scheduled payment date. When creating an amortization schedule, one must remember that the interest is dependent on the principal amount that was loaned and the number of months or years it would take you to pay the loaned amount. Of course, the bigger the principal loaned amount and the longer it takes for you to pay it, the greater the interest that is going to be generated. Therefore, if you would like for your loaned amount no matter how big or small it is, to be getting little interest, it is best that you settle your balances under short duration and never put yourself into a situation where you earn penalties for not paying your scheduled amount on time as arrears get some penalty interest compounded on top of your principal amount.
