Estimate what it costs to replace your Microsoft Access database – including data migration, interfaces and web access.
In brief
The investment frame for replacing an Access database is EUR 7,140 – 185,176 excl. VAT. Forms, VBA and interfaces move the project inside that band.
The upfront cost can be spread over 72 months. Terms are on the software financing page.

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.

FAQ
Small Access applications with a handful of forms can be replaced by a modern web application from EUR 7,140 – 185,176 excl.
VAT. Grown systems with extensive VBA logic, many reports and interfaces stay in the same investment frame. The calculator narrows the range by data model, user count and process complexity.
Access hits its limits with concurrent users, growing data volumes and remote work: database locks, corrupted files and missing web access are typical.
Add hard-to-maintain VBA macros and dependency on single knowledge holders – a modern database application removes these risks for good.
Legacy data is analysed, cleaned and migrated into the new data model – validated against the original database.
Historical records are preserved. Migration is priced as its own work package and runs in parallel to daily operations.
Have your Access application analysed
We review data model, VBA logic and interfaces and propose the best replacement path.
Usually a web application with a relational database (e.g.
PostgreSQL or MySQL): forms and reports are rebuilt as a browser UI, business logic moves from VBA into maintainable server code. Any number of users can work simultaneously – remotely and on mobile too.
Yes.
Replacing by module works well: critical forms and processes first, then reports and edge cases. Access stays available read-only during the transition, so daily business remains stable.
Small applications are replaced in 6–10 weeks, medium systems in 3–5 months.
The amount of VBA logic, the number of reports and legacy data quality drive the timeline.
| 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. |

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.

This result is only a non-binding indication based on typical assumptions. Effort and price must be calculated individually for your project.
A transparent four-step process for validating the Access Replacement indication with concrete requirements.
1. Confirm scope and target outcome
We clarify the business outcome, user groups, and boundaries relevant to Access Replacement.
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.
