How much SaaS spend is typically wasted?

Industry studies consistently find that 20 to 30% of paid SaaS licenses go unused. On top of that, companies typically lose additional spend to unchecked annual price increases, forgotten auto-renewals and poor contract-negotiation timing. Collectively, total SaaS waste commonly ranges from 20 to 40% of the software budget for organisations without active renewal management.

How is SaaS waste calculated here?

The calculator uses four independently estimated buckets: (1) unused licenses = spend multiplied by your unused-licence percentage; (2) unchecked price increases = spend multiplied by average annual vendor price increase multiplied by a maturity-adjusted mistiming factor; (3) forgotten renewals = spend multiplied by a forgotten-renewal rate; (4) poor contract timing = spend multiplied by a negotiation factor. All factors are sourced from published industry benchmarks and are fully disclosed in the methodology section. Total waste is capped at 55% of spend.

What counts as a forgotten renewal?

A forgotten renewal is a contract that auto-renews for another full term when the organisation did not actively decide to continue it. Common examples include: SaaS tools trialled and abandoned but never cancelled, software for a team or project that no longer exists, and duplicate tools that crept in when one team didn't know another team already had the same vendor. Lapsewise tracks renewal dates and sends reminders before the cancellation window closes so renewals become deliberate decisions.

How we estimate this

The calculator uses four independently-estimated waste buckets. Each is a transparent multiplication of your spend by a factor derived from published industry benchmarks for license utilization, vendor price escalation, and negotiation outcomes. Adjust the sliders to your reality; the methodology is unchanged.

Unused licenses

Spend x unused%

You pay for every seat whether or not it logs in. Straight multiplication of spend by your unused share.

Unchecked price increases

Spend x price-increase% x mistiming-factor

When a renewal auto-rolls, the vendor's increase lands unnegotiated. The mistiming factor is the share of increases that go unchallenged given your procurement maturity.

Forgotten renewals

Spend x forgotten-renewal-rate

The share of contracts that renew for another full term when nobody wanted them: the tool someone trialed, the team that churned. This rate falls sharply once renewals are actively tracked.

Poor contract timing

Spend x negotiation-factor

Discounts left on the table by renewing late or under deadline pressure instead of negotiating 60 to 90 days out. Benchmark negotiation savings run 2 to 6% of spend.

Maturity factor table

Procurement maturity	Negotiation factor (g)	Forgotten-renewal rate (f)	Mistiming factor (m)
Ad hoc	6.0%	7.0%	85.0%
Somewhat managed	4.0%	4.0%	55.0%
Actively managed	2.0%	1.5%	30.0%

Sanity cap

Total waste is capped at 55% of spend. If the four buckets add up to more, the model applies a proportional scale-down and notes the cap. No credible benchmark puts realistic total SaaS waste above this level.

Recoverable amount

The recoverable amount = forgotten renewals + poor contract timing + 60% of unchecked price increases. The 60% represents the share of vendor price increases that a team showing up to negotiations 60 to 90 days before renewal can challenge or offset. Unused-license waste requires seat-by-seat audits, so it is excluded from the "just track renewals" claim.

Limitations

This is an estimation model, not an audit. Factor defaults are drawn from published industry ranges for license utilization and negotiation savings; your actual situation will differ. The model uses USD as the display currency; if your spend is in another currency, the ratios and percentages still hold. Enterprise contracts are often governed by negotiated terms that differ materially from vendor-list conditions. Use this as a conversation-starter with your finance or procurement team, not as a definitive figure.
