Shadow IT Risk Calculator
Shadow IT costs a small team in three places: spend nobody owns, capabilities paid for twice, and renewals re-priced without anyone deciding to keep them. This page turns six readings from your own statements into those three numbers, then adds them where adding is honest. Every input is yours; the model ships no industry averages and no benchmark percentages.
If you want the underlying mechanism first — trials that auto-convert, one tool billed twice, renewals with no owner — read Shadow IT in Small Teams and come back.
Six inputs, all read off your own statements. Nothing here is sent anywhere — the arithmetic runs in this browser tab and no value is stored.
Distinct SaaS subscriptions the company pays for, counted once per tool.
One number for the whole set, read off a card statement. Currency: USD.
Share of annual spend on tools nobody in the company is accountable for.
Share of annual spend where two tools do the same job for the same people.
Share of annual spend renewed without anyone re-approving it.
How much more the slipped renewals cost versus the prior term.

Low relative exposure
The score is the mean of your three percentage inputs, split at 10% and 25%. Those cut points are this page's own convention, not an industry benchmark, and no threshold here authorises or blocks a purchase.
Show the exact arithmetic
annual_spend = 0 × $0 × 12
= $0
unowned_spend = annual_spend × 0.0000
= $0
duplicate_cost = annual_spend × 0.0000
= $0
renewal_slip_cost = annual_spend × 0.0000 × 0.0000
= $0
estimated_recoverable = duplicate_cost + renewal_slip_cost
= $0What the three buckets mean
Spend with no named owner is the part of your bill that nobody in the company is accountable for. It is not automatically waste: some of it is fine and simply undocumented. It is listed separately because it cannot be cut until someone is named for it.
Duplicate coverage is two tools doing the same job for the same people. One side is usually cancellable without dropping a capability, which is why it counts toward the recoverable figure.
Renewal slip cost is the uplift paid on terms nobody re-approved — the auto-converted trial, the repriced annual plan, the seat count that grew quietly. The money is already spent; the lever is the next term.
The arithmetic, in full
annual_spend = tools × monthly_cost_per_tool × 12 unowned_spend = annual_spend × unowned_pct duplicate_cost = annual_spend × duplicate_pct renewal_slip_cost = annual_spend × slip_pct × uplift_pct estimated_recoverable = duplicate_cost + renewal_slip_cost
Percentages enter as decimals. The expanded version of every line, with your own values substituted, sits under Show the exact arithmetic above — you can re-do any of it on a calculator and get the same result.
What this does not include
- Security exposure. Data sitting in an account no contract covers is priced separately, in “When does shadow IT become a security problem” on the article linked above.
- Labour. Finding the tool, naming an owner, and cancelled seats all take person-hours this model does not count.
- Anything you did not enter. If your real spread of per-tool prices is wide, one average will flatten it — run the calculator twice with two tool counts instead of trusting one blended number.
FAQ
What does the shadow IT risk score actually measure?
The mean of your three percentage inputs — unowned spend, duplicate coverage, and slipped renewals — banded at 10% and 25%. It measures how much of your spend nobody is accountable for. It does not measure breach likelihood, and the two cut points are this page's own convention rather than an industry standard.
Where do the six numbers come from?
Your card statements and your billing inbox over the same twelve months. Sweep the inbox for receipts, reconcile against the card, and whatever appears in only one of the two sources is the shadow set until a named person owns it. That count is your first input.
Is the recoverable number a savings promise?
No. Duplicate coverage is spend on a capability you already pay for twice, so cancelling one side is usually actionable. Renewal slip cost is money already spent; acting on it changes the next term. Treat the sum as the size of the conversation with your accountant, not as a forecast.
Do you collect what I type in?
No. There is no request and no storage: the component computes in the tab and the values disappear when you close it. Nothing is needed to run it — no account, no mailbox connection.
Next step
The calculator tells you the size of the hole. It cannot tell you which tool, on which card, renews on which date — that is the inventory step, and it starts from the billing email you already have. Start a free audit reads your mailbox, builds the inventory, and the plans page states which parts are free and which are paid.
If the arithmetic itself is the thing you want argued with — a coefficient you disagree with, a bucket you think should not count — send it to the contact form and quote the line. The formula above is the whole model; there is no hidden weighting to disagree about privately.
