Save Your SaaS Audit
Create a free SpendKeep account to track your SaaS spend month-over-month — no bank sync ever required.
The average funded startup maintains subscriptions to 73 SaaS tools. According to multiple SaaS management audits, between 25% and 40% of those licences are unused at any given moment. What makes this problem exponentially dangerous is headcount growth: every new hire potentially provisions additional seats across your entire toolstack, multiplying idle spend automatically.
Unlike fixed costs, SaaS expenditure is uniquely volatile. A 20% headcount expansion in a year with 30% unused licences doesn't produce 30% waste — it produces compounding waste, because new seats are provisioned at the same idle ratio as your existing stack. The formula embedded in this estimator captures that compounding effect precisely.

Most SaaS management platforms require you to connect your corporate banking credentials or grant OAuth access to your financial accounts to track spend. This creates an immediate data aggregation risk — your vendor's security posture becomes your security posture. High-profile settlements, including the $58 million Plaid class-action over data minimization failures, demonstrate the real financial and reputational cost of this approach.
SpendKeep is architecturally designed to track SaaS spend — and every other category of financial data — through structured manual entry and CSV import. Your financial footprint never leaves your control. Compare this calculator's privacy-first approach to our Privacy Risk Calculator, which quantifies the attack surface created by automated bank synchronisation.
