What is the Realization Principle?
The realization principle is a core revenue recognition rule in accrual accounting: revenue is recorded when it is earned and realizable, not simply when cash changes hands. It underlies how businesses report sales, services and long-term contracts on the income statement.
The realization principle states that revenue should be recognized when it is earned (goods delivered or services performed) and realizable (collection is reasonably assured) — regardless of when cash is actually received.
- •Revenue recorded when earned

- •Required under GAAP/IFRS for most companies
- •Reflects economic activity, not just cash flow
- •Revenue recorded only when cash is received
- •Ignores timing of the underlying work
- •Simple but distorts period performance

Step-by-step worked examples
A construction company signs a $1,500,000 contract. By year-end it has incurred $300,000 of the $1,000,000 total estimated cost. How much revenue should it recognize?
% complete = 300,000 / 1,000,000 = 30% Revenue recognized = 30% × 1,500,000 = $450,000
A software company delivers a product on Dec 28 but the customer pays on Jan 15. Under the realization principle, when is revenue recognized?
Revenue is earned when the product is delivered (Dec 28), not when cash is received. So revenue is recorded in December, even though payment arrives in January.
A retailer receives a $5,000 customer deposit in November for goods to be delivered in January. How much revenue is recognized in November?
The goods have not been delivered — revenue is not yet earned. $0 is recognized in November; the $5,000 is recorded as unearned revenue (a liability) until delivery in January.
