What is the plugin?
Proven real estate calculators for your WordPress site
immotap Rechner is a free WordPress plugin that lets you build real estate calculators right into your website. Your visitors work out market value, closing costs or energy efficiency inside your own content, without detouring to another site.
Setup takes only a few minutes and needs no coding at all. Every calculator is the same one running on immotap.de: professionally checked, optimized for mobile and cleanly designed. For each calculator you choose the look, the language and whether a calculation should turn into an inquiry.
The plugin is made for real estate agents and property websites that want to give visitors real value while keeping full control of their contacts. Nothing is sent to immotap, every inquiry stays on your own website.

How it works
Embedded in four steps
No developer, no sales call, no external platform. From download to a working calculator takes just a few minutes.
Install the plugin
Upload the plugin to WordPress and activate it. A WordPress website from version 6.4 is all you need.
Set it up quickly
Set once which email address inquiries go to, how long they are kept and how the calculator looks.
Embed a calculator
Place the calculator you want into a post or page in a few clicks. As many per page as you like.
Receive inquiries
Switch on lead capture and collect contacts directly in your WordPress, with email notifications.
You don't need a developer
If you can create a page in WordPress, you can embed a calculator. If you have questions, the included guide walks you through it step by step.

Data protection
GDPR was never an afterthought
The plugin is built to be data-minimal and makes it easy to stay compliant. immotap receives and stores nothing, you remain the data controller.
- All personal data stays on your own website
- Documented consent with a timestamp (Art. 7 GDPR)
- Freely configurable retention with automatic deletion
- Per-person access and erasure in a few clicks
- Ready-made text block for your privacy policy
- The IP address is not stored by default
- No tracking cookies and no hidden data sharing
- Effective protection against spam inquiries
The notes in the plugin are guidance and do not replace legal advice. As the data controller, the legal responsibility remains with you.
The difference
Why your own calculator plugin
The usual workaround
- Calculators from other providers: your prospects end up elsewhere and the design does not match
- Having something custom built: expensive, time-consuming and a constant source of bugs
- Inquiries land with third parties or are lost entirely
- Extra cookie banners and unresolved data protection questions
With immotap Rechner
- Proven real estate calculators embedded on your website in minutes
- Your prospects stay with you, nothing is shared with third parties
- Inquiries land directly with you, in your own WordPress
- GDPR-compliant, with no extra cookies and no tracking
