About this gig
Your site sends people to a contact form when all they wanted was a number.
They wanted their monthly payment. Their premium. Their total cost. So they leave and check somewhere else.
I put that number on your page.
What you get:
- A working calculator built in plain JavaScript
- Your formula, your fields, your labels
- Works on phone screens
- Commented code you or your developer can edit later
- Files handed over, or installed on your site
How it works:
1. You send me your formula, a sheet, or even a photo of it on paper
2. I build it and send you a live preview link
3. You test it, I fix what needs fixing, then it goes live
I have been coding for 20 years and I have built dozens of these. Loan, insurance, pricing, cost, margin. If you can explain the math, I can build it.
Not a fit if you need a full site redesign or a payment system. I do the calculator.
Message me your formula before you order. I will tell you which package fits. If it is not something I can build well, I will say so.

FAQ
Do you work with WordPress, Shopify or plain HTML sites?
Yes. I build in plain JavaScript, so it drops into WordPress, Shopify, Wix, Webflow or a hand coded site. If your site runs on PHP or React, I can match that instead. Tell me your platform first
I cannot explain my formula properly. Can you still help?
Yes. Send an Excel sheet, a screenshot, or a photo of it written on paper. I read the math and send you my understanding in writing before I start coding. You confirm it, then I build.
Why does a complex calculator cost more than the basic one?
Price follows the number of fields and the number of rules. One formula with five inputs is quick. A multi step form with tiers, conditions and a PDF output takes hours of testing. Message me your case and I will quote it.
What if the calculator returns a wrong number?
I fix it, and that fix does not count as a revision. I test every calculator against sample numbers you give me before delivery. Wrong math is a bug, not a change request.
What happens if you deliver late?
I set delivery at 3 to 6 days and I usually finish sooner. If something on my side slips, I tell you before the due date, not after. Fiverr also lets you cancel if a late delivery breaks your plan.
Can I edit the calculator myself later?
Yes. You get commented code and a short note showing where the formula sits. If you read basic JavaScript you can change rates and labels yourself. If not, small updates are cheap.
Who owns the code after delivery?
You do. Once the order is complete the code is yours to use, edit and reuse on your own sites. I will not show your business name or your formula in my portfolio unless you tell me I can.
Do you need access to my website?
Only if you want me to install it. For that I need admin or FTP access, shared through Fiverr. If you prefer, I deliver the files with a short install guide and your own developer handles it.
