Also called self-amortizing, level payment.

What it means
Each payment is identical, and each splits between interest and principal. Early on most of it is interest because the balance is large; as the balance falls, more of each payment goes to principal. The final payment closes the loan.
The alternatives all leave something behind. Interest-only pays no principal during the interest-only period. A balloon amortizes on a long schedule but matures early, leaving a large sum due that usually has to be refinanced. Negative amortization, rare in business lending, adds unpaid interest to the balance.
The practical consequence of full amortization is that time and cost are linked. Interest exists because the balance exists, so shortening the life of the loan reduces what it costs.
Where this one catches people
Comparing an amortizing loan to a fixed-cost advance by their total dollars paid gets the answer backwards. The loan's interest is contingent on time and can be cut by paying early; the advance's cost is fixed and cannot. Two offers showing the same total repayment are not the same price, and the one that responds to early payoff is worth materially more than the one that does not.
Worked through
$100,000 over five years at 10% amortizes to about $2,125 a month. The first payment is roughly $833 of interest and $1,292 of principal; the last is almost entirely principal. Paid to term the loan costs about $27,500 in interest. Paid off at month 24, well under half of that is ever incurred.
