SaaS Stack Audit

Find out what your subscriptions actually cost — and which ones are quietly bleeding.

Duplicate tools, unused seats, and annual contracts can turn a manageable software stack into recurring waste. These calculators help you measure your own stack instead of relying on an industry-average claim.

Source standards for SaaS calculations

This category only uses public list pricing when a vendor publishes a clear monthly or annual plan. We exclude contact-sales plans, bundled enterprise contracts, usage-only infrastructure products, and regional prices we cannot verify from a public page. For manual audit pages, the source of truth is your own invoice, renewal email, or billing export. Document the renewal owner too. Your own invoice always beats our defaults; the calculator is meant to catch waste, not replace accounting records.

How to use this section

Work through the numbers in the order that prevents bad decisions.

  1. 01

    Begin with invoices, not guesses

    The subscription audit works best when every line item comes from a real invoice or card statement. Defaults are only placeholders; the money is in finding duplicated tools, unused seats, and renewals nobody owns.

  2. 02

    Check renewal risk before annual discounts

    Annual billing can save money, but only if the tool survives the year. Run the annual-vs-monthly calculation for every renewal over $1,000 before accepting a vendor's headline discount.

  3. 03

    Use unit economics for growth spend

    LTV, CAC, and churn decide whether software spend is supporting revenue or just adding overhead. The breakeven calculator is the guardrail before adding another product-led-growth tool.

Guides & deep dives

Long-form explainers that go deeper than the calculators — the hidden traps, the real math, and how operators actually cut the bill.

Why this category exists

  • SaaS sprawl is real

    Unused seats, overlapping tools, and unattended renewals are measurable sources of waste. The audit starts from your own invoices, seat counts, and usage instead of assuming a universal percentage.

  • Annual contracts hide churn cost

    Companies pay 20% upfront discounts for tools they'll cancel in month 9. The discount is real, but so is the loss.

  • Per-active-user is the only real metric

    Aggregate spend tells you nothing without dividing by actual weekly users. We do that division.

FAQ

Do you integrate with my accounting software?
No. The current calculators use manual inputs and do not connect to bank or accounting accounts.
How accurate are your default SaaS prices?
The default examples only include products with a current public per-seat monthly and annual USD price that fits this calculator. Usage-based, per-host, bundled, regional, and contact-sales products are excluded. Replace every default with your actual invoice before making a budget decision.
