Indicative annual saving — a reduction in cost per onboarding, releasing analyst hours a year

Labour is costed at the fully loaded hourly rate you entered. Screening and data cost is held constant across both scenarios, because you still screen every customer — automation changes who touches the file, not whether the check runs.

How to read this. These are modelled figures based on the inputs you supply, not a quotation and not a guarantee of outcome. Real savings depend on your customer mix, your regulatory obligations, the quality of your data sources and how much of your process is genuinely rules-based. Nothing you type here is transmitted or stored.
Cost model

What actually makes KYC expensive

Most firms underestimate their cost per onboarding because they count the obvious line item — the screening subscription — and ignore the one that dominates the total. In a manual or semi-manual process, analyst time is usually seventy to ninety per cent of the cost of onboarding a customer, and the largest single contributor to that time is not the check itself but the waiting, chasing and re-keying around it.

The four costs in every onboarding

  • Analyst handling time. Reviewing documents, entering data into the core system, reading screening output, discounting false positives, writing the rationale. This is the number most worth attacking.
  • Data and screening. Identity verification, document authentication, sanctions, PEP and adverse media lookups, corporate registry pulls. Usually a fixed per-case cost you cannot remove, only negotiate.
  • Exception handling. The cases that need enhanced due diligence, a second document, a UBO chain unwrapped by hand or a compliance escalation. A small share of cases absorbing a large share of the effort.
  • Rework and abandonment. Files reopened because a document expired mid-process, data was re-keyed incorrectly, or the customer walked away and came back. Rarely measured, always material.

Why the exception rate matters more than the average

Move the exception slider in the calculator and watch the annual figure move disproportionately. If a standard case takes thirty-five minutes and an exception case takes another ninety on top, then a fifth of your volume is consuming close to half your analyst capacity. That is why reducing average handling time across the board is usually less valuable than removing the causes of exceptions: incomplete document capture at the front end, weak false-positive management in screening, and manual reconstruction of corporate ownership structures.

Where automation actually changes the number

Automation does not make screening free. It changes who touches the file. A clean retail case with an authenticated document, a passed liveness check, a clear screening result and a low risk score does not need an analyst at all — it needs an analyst to be available for the case that does. That is what straight-through processing means in practice, and it is why the calculator models a residual review cost on automated cases rather than assuming they cost nothing.

Beyond the unit cost

The costs that never make it into the model

Cost per onboarding is the easiest number to defend in a business case, but it is rarely the largest number on the table.

📉

Abandonment

Applicants who start onboarding and never finish are pure lost revenue. Multi-day, document-heavy processes lose a meaningful share of the funnel before activation, and that loss usually dwarfs the analyst cost of the cases that do complete.

Time to revenue

Every day between application and activation is a day the customer is not transacting. For lending, payments and fund subscription flows this delay has a direct, measurable carrying cost.

⚖️

Remediation

Files closed with a gap have to be reopened later, at scale, under a deadline. A back-book remediation exercise typically costs several times what it would have cost to onboard correctly the first time.

Questions

About KYC costs

What does KYC cost per customer?+
It varies enormously by segment. A simple retail individual onboarded through a well-automated digital flow can cost only a few units of currency in data and a couple of minutes of oversight. A complex corporate or fund client with a multi-layer ownership structure, several UBOs, EDD requirements and manual registry work can run into hundreds. The calculator lets you model your own blend rather than relying on an industry average that may not describe your book at all.
Should screening data cost be included?+
Yes. Identity verification, document authentication, sanctions, PEP and adverse media lookups and registry pulls are a genuine per-case cost and should sit in the model. What automation changes is the labour around them, not the fee itself, which is why the calculator holds data cost constant in both scenarios.
What straight-through rate is realistic?+
It depends almost entirely on customer mix. High-volume retail and simple SME books can reach a high straight-through rate because most cases are genuinely low risk and rules-based. Corporate, trust and fund books will be lower, because UBO resolution and EDD require judgement. Set the slider conservatively for your own segment rather than to a headline figure.
Does automating KYC reduce headcount?+
In most deployments it reallocates rather than removes it. Analyst capacity released from routine cases goes into the exception cases, EDD, periodic refresh of the back book and quality assurance — all work that is usually under-resourced. Firms growing their customer base tend to use automation to absorb volume growth without adding headcount rather than to cut it.
How should we account for periodic KYC refresh?+
Refresh is a recurring cost on the whole book, not just on new customers, and for an established institution it often exceeds the cost of new onboarding entirely. This calculator models new onboarding only. If you want the full picture, add your annual refresh volume as additional onboardings — the per-case economics are broadly comparable.
Can One Constellation model this against our real data?+
Yes. Our solutions team will build a costed model against your actual volumes, customer mix, exception rates and regulatory obligations as part of the demo process. Book a demo and bring your numbers.
