What This is About

Want to showcase the value of your solution to potential customers? A ROI Calculator helps convert features into tangible financial impact.

This tutorial walks you through how to generate your own ROI calculator using ChatGPT (or similar AI tools) and submit it to be hosted on our website. No coding experience required.

What You’ll Need

  • A clear understanding of the ROI drivers for your product or service
  • An account with ChatGPT or another AI tool (e.g., Claude, Gemini, etc.)
  • Basic idea of what your calculator will do (e.g., time savings, revenue uplift, cost reduction)
  • 15–30 minutes of focused time

✅ Step-by-Step: Build Your ROI Calculator with ChatGPT

1. Start a New Chat with GPT-4 (or equivalent)

Use this prompt to get started:

Act as a developer. Help me create a simple ROI calculator in HTML, CSS, and JavaScript.

The calculator should let users input variables like [input1], [input2], and [input3], along with any other relevant fields. It should compute outputs such as [output1], [output2], and other meaningful metrics.

The output must include ROI as a percentage and/or dollar value, and it should also present actionable insights based on the user's inputs — for example, suggestions for improvement or interpretation of the results.

The code should be standalone and mobile-friendly. Provide the HTML, CSS, and JavaScript code separately.

Replace [input1], [input2], etc. with variables relevant to your product (e.g., “Monthly leads,” “Conversion rate,” “Average deal size”).

2. Customize the Output

ChatGPT will generate code like this:

  • An <input> form for your variables
  • A calculation script using JavaScript
  • A display area for the results
  • Basic CSS styling

Modify or re-prompt as needed until you are happy with the layout and formula.

3. Test It Locally

Copy the code into a free editor like JSFiddle, CodePen, or your local IDE and test it. Make sure:

  • Calculations are correct
  • The layout looks clean (especially on mobile)
  • Inputs and outputs are user-friendly

4. Submit It to SalesSuccess

Once you are ready, submit your calculator using form here.
We will review, host it under a dedicated URL, and showcase it in our growing ROI Calculator Library.

Example Prompts You Can Use

Here are a few example prompts to help you get started faster:

🔸 For a B2B SaaS Tool:

Help me build an ROI calculator for a CRM tool. Inputs: monthly sales leads, conversion rate, average deal size. Output: revenue before and after CRM, and ROI.

🔸 For a Consulting Service:

Create a calculator to show time savings from a new onboarding process. Inputs: number of employees onboarded per month, hours saved per person, average hourly wage.

🔸 For a Marketing Agency:

I want a calculator to show return on ad spend (ROAS). Inputs: ad budget, conversions, average order value. Output: revenue and ROAS %.

Tips for Better Results

  • Be clear about your formula or logic — you can even sketch it out before asking GPT
  • Ask GPT to add validation or tooltips for clarity
  • Keep it focused — don’t overload with too many inputs
