Key takeaways
Amortization is the accounting method for spreading the cost of an intangible asset, like a patent, trademark, capitalized software, or acquired goodwill, over its useful life. Each period, a slice of the cost becomes a non-cash expense on the income statement. It's the intangible-asset counterpart to depreciation, which covers physical assets.
A company that capitalizes $150,000 of internally developed software with a three-year life amortizes $50,000 per year.
Amortization affects reported earnings and, for some intangibles, taxable income, so how you capitalize and amortize things like software or acquisition costs shapes both your P&L and your tax position. Consistent treatment matters most during fundraising and M&A diligence, where buyers scrutinize how intangibles are valued and expensed.
