Built a simple financial calculator website (GST, SIP, EMI) — would love honest feedback

Hey everyone,

I recently built a small website that includes financial calculators like GST, SIP, and EMI. The goal was to keep it simple, fast, and easy to use, especially for people who just want quick calculations without distractions.

I’m still early in the process and would really appreciate honest feedback from this community:

UI/UX (is anything confusing or annoying?)

Accuracy / logic of calculations

Performance / loading speed

Missing features you’d expect

Anything that feels unnecessary or poorly designed

I’m not trying to sell anything — just genuinely looking to improve and learn.
If you’re willing to take a quick look, here’s the link:https://calculatefinance.xyz/

Thanks in advance 🙏
