About this tool
What the Penetration Testing Cost Estimator does
Penetration tests are usually priced by tester days, so cost follows scope. This calculator converts web applications, external IP addresses and internal network testing into days using planning assumptions you can edit, then adds reporting and retesting.
Formula
- Testing days = applications × days per app + IPs ÷ IPs per day + internal days
- Total days = (testing + reporting) × (1 + retest allowance)
- Cost = total days × day rate
Worked example
Using the starting values in the calculator above:
| Input | Value |
|---|---|
| Web applications | 2 |
| Days per application | 5 |
| External IP addresses | 32 |
| IP addresses per day | 16 |
| Internal network testing days | 5 |
| Reporting days | 2 |
| Retesting allowance | 20% |
| Day rate | $1,400 |
| Result | Value |
|---|---|
| Estimated cost | $31,920 |
| Total tester days | 22.8 |
| Hands-on testing days | 17.0 |
How to read the result
Scope drives price more than anything else. Authenticated testing of several user roles, APIs and complex workflows can double the days for a single application.
Ask suppliers to quote retesting separately so you can confirm fixes without paying for a full new test.

Questions
Questions about this tool
The things clients actually want to know — costs, timelines, ownership and what happens after launch.
It depends on scope and day rates. A single small web application can take a few days, while large estates take weeks.
Testing commonly runs from a few days to several weeks, plus time for reporting.
At least annually and after major changes is a common practice, and some standards require it.
