Estimate a technical code, architecture and quality audit without conflating it with penetration testing.
Software audit costs
The Software Audit cost calculator provides an immediate, non-binding cost range without requiring an email address or registration. It combines your project inputs with documented calculation rules and experience from more than 250 software projects.
Use the calculator right below for an instant first estimate – no sign-up and no fixed-price commitment. We align scope, risks, and assumptions in a conversation before a binding quote.
The calculation follows six visible stages. All figures remain planning values until scope and assumptions have been reviewed.
1. Capture inputs
The calculator records the visible project, volume, complexity and operating parameters selected on this page.
2. Add fixed components
Fixed base modules and selected add-ons are added without mixing them with recurring charges.
3. Apply multipliers
Quantity, complexity and scope factors multiply only the cost components identified for them in the calculator model.
4. Create the range
The calculator applies its documented lower and upper uncertainty factors to the base result; ROI views keep investment and savings visible separately.
5. Round and calibrate
Monetary result fields are rounded to the nearest whole euro. Public project-cost components are calibrated with the centrally maintained display factor.
6. Classify the result
The result is shown as non-binding guidance. A binding quote requires scope, data, integrations, risks and acceptance criteria to be reviewed.
Efficiency or discount factor: A central display factor of 0.7 is applied to public project-cost components to keep all calculators aligned with the currently reviewed pricing basis. It is not a customer-specific discount; customer-entered wages, revenues and existing operating costs are not reduced.
Why this is not a binding quote: The calculator cannot verify complete requirements, third-party dependencies, data quality, legal constraints or acceptance criteria.
A technical software audit makes code, architecture, and operational risks visible before an investment decision. The calculator estimates the review effort.
The estimate reflects the selected assessment depth as a non-binding planning range.
A software audit remains distinct from penetration testing and a dedicated security assessment.

FAQ
Effort depends on codebase size, application count, review depth, and available documentation.
The estimate covers the review itself, the findings, their prioritization, and a results workshop.
The review examines these technical areas:
Without reliable documents, reviewers first have to rebuild the picture.
They reconstruct system boundaries, data flows, and earlier decisions from code, configuration, and interviews. This extra step keeps the findings free of wrong assumptions.
No.
This calculator assesses code quality, architecture, and technical sustainability. Vulnerability scans, penetration testing, and security compliance require a dedicated security scope.
Leaders receive a prioritized risk register, effort ranges, and a practical sequence for stabilization or modernization.
Together these outputs turn technical debt into an investment plan. It stops being an open-ended engineering concern.
We separate every observation from its impact, priority, and recommended action.

| Model | When it fits | Budget & flexibility | Typical risks |
|---|---|---|---|
| Fixed price (fixed scope) | Clearly defined scope, stable requirements, repeatable delivery. | Predictable total cost; little room for change without a change order. | Scope creep leads to change orders or quality trade-offs. |
| Time & Material | Discovery, legacy, evolving requirements, or close collaboration. | Maximum flexibility; budget transparent via hourly or daily rates. | Without prioritisation, effort can grow—backlog and reviews matter. |
| Retainer / maintenance package | Ongoing operations, updates, small features, and support. | Agreed capacity per month; predictable follow-on cost. | Large changes may still need a separate estimate. |
| Hybrid (milestone + T&M) | MVP or phased releases with clear go-lives, then iterate. | Core delivery fixed price; extensions on a time-and-materials basis. | Define contractually what is in scope vs. extra work. |
Calculators on this page provide indicative ranges; we choose the right model with you based on risk, scope, and planning horizon.
The ranges shown are indicative. For a binding quote we discuss scope, priorities and funding options in a free intro call. Many digitalization projects qualify for grants – try our funding calculator.

What will a technical assessment of your software cost?
Interactive estimate based on your inputs.
Non-binding project range from the software cost calculator: EUR 10,332 – 372,623 excl. VAT.
Methodology: The estimates are based on historical project data, complexity drivers and standard implementation assumptions. Results are a non-binding indication only; effort and price must be calculated individually.
If you are still deciding
If you are ready to implement
A transparent four-step process for validating the Technical Software Audit indication with concrete requirements.
1. Confirm scope and target outcome
We clarify the business outcome, user groups, and boundaries relevant to Technical Software Audit.
2. Review data, interfaces, and risks
We validate integrations, data quality, security, compliance, and operational dependencies.
3. Check the calculator assumptions
We compare the selected parameters with the real system landscape and document deviations.
4. Prepare the precise quote
You receive a scoped proposal with milestones, exclusions, price model, and next decision point.
