This is what we’ll build by the end of this tutorial – a professional ROI calculator with a cool interface and a secure interface, all on WordPress!
And the best part? I Will Give you all the code snippets, you just need to copy, test, and enjoy!
Why An ROI Calculator?
I chose an ROI calculator for this tutorial simply because it’s straightforward to understand and implement. The exact same principles apply whether you’re building an calorie counter, BMR calculator or any other calculator.
I’ve built hundreds of custom tools across various industries, including PowerKit, TubeDigest, and PromoterKit.
Today, I’ll show you exactly how to build one from scratch, progressing through 5 levels from basic to a professional SaaS-quality tool.
Level 3: Native-Feeling Design
At this level, we’ll update the styling to make the calculator feel more integrated with your website’s natural design, so that wherever you add it, it blends in with the page, rather than standing out.
