How to Amortize Capitalized Software Development Costs Monthly Over the Useful Life
Monthly amortization of the capitalized software development intangible asset over the estimated useful life of the product.
| Account Name | Type | Debit ($) | Credit ($) |
|---|---|---|---|
| Amortization Expense (Capitalized Software) | Expense (+) | 4,167.00 | - |
| Accumulated Amortization (Software) | Contra-Asset (+) | - | 4,167.00 |
💡 Accountant's Note
A $250,000 capitalized software asset with a 5-year useful life is amortized at $4,167/month. Amortization begins when the product is available for use, not when development starts.
Practitioner & Systems Framework
💻 ERP Architecture
Amortization begins on the go-live date (the date the product is available for its intended use), not when development spending started. For SaaS products with ongoing feature additions, each significant new feature may create a separate asset tranche with its own amortization start date. Review the useful life assumption annually — if technology changes make a module obsolete faster than expected, accelerate the amortization.
⚠️ Audit Flags
Auditors verify the amortization start date matches the actual go-live date (supported by deployment records or release notes). They also test the useful life assumption — a 5-year life for a rapidly evolving SaaS feature set may be challenged. Annual impairment indicators (declining user adoption, product replacement decisions) must be assessed.
📄 Required Documentation
Product go-live date evidence (release notes, deployment log, customer go-live notifications), useful life assessment memo, amortization schedule by asset/tranche, Accumulated Amortization roll-forward, and annual impairment indicator review.
