Stack Corral: SaaS Sprawl Auditor
Estimate wasted spend and identify cleanup priorities before renewals lock in.

Export summary
Carry this snapshot into procurement and renewal reviews.
Instructions
Current tools used
Enter the number of paid SaaS tools currently active in your stack. Count only tools with meaningful recurring cost, not free utilities or one-off experiments.
Average total monthly cost per tool ($)
Enter average spend per tool including base subscription, add-ons, and typical overage charges. Use a 3-month average if billing fluctuates.
Gross monthly revenue ($)
Enter current gross monthly revenue so spend can be normalized by business size. If unknown, use a conservative estimate; the model enforces a minimum denominator of 1.
Average user seats per tool
Enter the average number of provisioned seats per tool. Higher seat counts usually increase administrative load, permission complexity, and renewal risk across the stack.
Average unused seats per tool
Enter the average seat count you pay for but do not use. If uncertain, start with a conservative estimate and refine after seat-audit data is collected.
Tools with no clear owner
Enter how many tools lack one accountable business owner. Ownerless tools are harder to govern and often drive avoidable renewal and adoption waste.
Tools missing renewal dates
Enter how many tools do not have a known renewal date in your tracking system. Missing dates usually cause rushed decisions and lost negotiation leverage.
Duplicate-function tools
Enter the number of tools that overlap on the same core job (for example, two project tools or two survey tools). This is your starting point for consolidation planning.
How to use results
Review spend baseline, coverage metrics, and sprawl score together, then pick one cleanup lane for the next 30 days. Export the summary and assign an owner with a measurable target.
Interpretation notes
Total SaaS spend per month
This is your baseline monthly stack cost using tool count multiplied by average total monthly cost per tool. Use this as your top-line benchmark before any consolidation or renewal negotiation work.
Annualized SaaS spend
This projects current monthly spend over 12 months without optimization. It gives finance and ops a common planning figure for budgeting and savings targets.
Estimated cost per seat per month
This is computed from average total monthly cost per tool divided by total seats per tool (active plus unused). If this value is high, review plan tiering and whether paid seats are aligned with real usage.
SaaS spend as a share of monthly revenue
This normalizes stack cost against your current monthly revenue base. Use it to compare sprawl pressure across months as revenue changes.
Duplicate tool categories flagged
This count highlights where multiple tools perform overlapping jobs. Start with one duplicate category, confirm required capabilities, then consolidate to one primary system with clear ownership.
Estimated wasted seat spend per month
This estimates spend tied to unused seats across the stack using computed seat cost. It is a direct savings opportunity and usually the fastest cost-reduction lever.
Wasted seat spend share
This shows how much of monthly SaaS spend is likely tied to unused seats. Higher percentages indicate seat governance issues and justify tighter provisioning controls.
Tools with no clear owner
Ownerless tools tend to drift in usage, renewal timing, and policy compliance. Assign a business owner for each tool so decisions are accountable and auditable.
Tools missing renewal dates
Missing renewal visibility creates auto-renewal risk and weakens negotiation leverage. Close this gap first so cancellation and negotiation windows are not missed.
Ownership coverage
Ownership coverage is the percentage of tools with an assigned owner. Raise this metric before major consolidation so cleanup decisions do not stall.
Renewal-date coverage
Renewal coverage is the percentage of tools with known renewal dates. Strong coverage supports proactive procurement planning instead of reactive contract handling.
SaaS sprawl score
The sprawl score combines duplicate overlap, ownership gaps, renewal gaps, and seat waste into one triage metric. Use it to prioritize cleanup sequence, not as a perfect financial forecast.
Suggested cleanup priorities
This recommendation adapts to your score band and highlights the next best action. Execute one cleanup track at a time, then rerun the calculator to measure progress.
Score Sensitivity
The SaaS sprawl score is a weighted sum of normalized components. Core scale drivers are tool count, average monthly cost per tool, and average user seats per tool, then governance drivers (duplicate-function tools, owner gaps, renewal gaps), unused-seat pressure, and revenue normalization via SaaS spend as a share of monthly revenue.
Sensitivity is intentionally highest on the three core scale drivers. As those increase, score contribution rises directly. Revenue only moderates context by adding pressure when SaaS spend consumes a larger share of monthly revenue.
This note highlights the largest weighted contributors to the current score so you can prioritize the highest-impact cleanup actions first.
