Amortization

The gradual repayment of a debt — or the write-down of an intangible asset — over a set period through scheduled installments.

Amortization has two related but different uses in finance. In lending, it's the process of paying off a loan through regular installments — each payment covers interest first, then reduces the principal balance. In accounting, it refers to spreading the cost of an intangible asset (like a patent or software license) over its useful life.

Why does it matter? Because it changes how expenses appear. Instead of one massive cost hitting the books on day one, amortization smooths it out over years — making profits look more stable and predictable. Investors love predictability.

Think of it like paying off Spotify Premium on a payment plan. You owe £120 for the year, so you pay £10 a month. Each payment chips away at the total. Amortization is exactly that — spreading a large obligation into smaller, predictable bites over time.

Real world: When you (or your parents) take out a mortgage, every monthly payment is amortized. In the early years, most of the payment covers interest; later, more goes to principal. Banks give you an amortization schedule — a table showing exactly how each payment breaks down over 25 or 30 years.

💡 Amortization turns big lump-sum obligations into manageable slices — it's the installment plan of the financial world.
