Deferred Revenue Waterfall Calculator

Deferred revenue is one of the most important line items on a SaaS company's balance sheet. It represents the gap between cash collected and revenue earned — a liability that must be carefully tracked and unwound each period.

A deferred revenue waterfall (also called a rollforward or bridge) provides a complete reconciliation:

• Opening balance — deferred revenue carried forward from the prior period
• Additions — new contract value entering the deferred pool (new bookings, renewals, expansions)
• Recognition — revenue earned during the period, reducing the liability
• Closing balance — remaining obligation carried into the next period

This schedule is essential for:

• Month-end close
• Board reporting
• Audit preparation
• Investor due diligence

It answers the fundamental question: “Where did our deferred revenue come from and where did it go?”
