I will build a custom price calculator for your service website


Level 1
About this gig
Help visitors estimate your service price without waiting for a manual quote.
I build a responsive calculator using your supplied pricing rules. It shows labeled inputs, clear results and validation. My portfolio contains a working, fictional Clearspace demo; its rates and results are examples, not client claims.
Basic: up to 3 inputs and 1 formula. Standard: up to 6 inputs, 3 conditional rules and a breakdown. Premium: up to 10 inputs, 5 rules and a browser print view.
All packages include source code, a setup guide, checks against your examples and first installation on one agreed compatible website. Send the URL/platform before ordering: custom-code access is required; compatibility is confirmed individually.
You provide the formula, content and 3 expected calculations. You own and pay for hosting/domain/platform plans. No paid API or maintenance subscription from me is required.
No payments, login, database, email, live data or custom PDF generator. Revisions adjust agreed rules/design; new rules or features need a separate quote. Defect fixes are separate from revision rounds. English/German chat.

FAQ
What do you need to start?
Your input fields, units, written formula, pricing rules, rounding/currency choices and at least 3 examples with expected results. Also provide your website URL/platform, language and design preferences. You supply and approve all business rules.
What counts as an input or a rule?
An input is one field. A conditional rule changes the calculation when a defined condition is met, such as one discount threshold. We count fields and branches before ordering. Each package covers one calculator and one supplied language, not several separate tools.
Will the calculator work on my website?
All packages include first installation on one agreed compatible site. Send its URL/platform before ordering. Static HTML or an approved custom-code/iframe route is required. CMS plugins, themes and platform upgrades are not included; I confirm the exact route first.
Can you develop my pricing formula?
You choose and approve the formula and business rules. I implement them and test against your expected examples and boundary cases. Choosing commercially suitable prices or validating your business model is outside this service.
Are payments, logins or external data included?
No. This is a browser calculator without payment, user accounts, databases, email delivery or live external data. You own and pay for your website/hosting/platform. No paid API or recurring maintenance subscription from me is required.
Does Premium include PDF export?
Premium includes a print layout that uses the browser's print/save-as-PDF function. It is not a custom PDF generator, email delivery system or quotation database.
What does a revision include?
One consolidated adjustment within the agreed design and rules. New formulas, fields or features are extra work. I fix reproducible defects against the agreed scope separately from revision rounds. Future price changes, monitoring and platform updates are optional paid work.
Can I try a working example?
Yes: https://benny-web-demos.benny-2205.chatgpt.site/calculator/ is my fictional Clearspace demo, created with AI assistance. Its rates are examples. No booking, payment or email is sent. Your package includes only the features agreed for your order.
What files and usage instructions will I receive?
HTML/CSS/JavaScript source, example calculations, setup/editing instructions and a list of any dependencies and licenses. I check the agreed installation and show how to change the supplied rates. Hosting accounts stay yours; no ongoing seller subscription is needed.
