I Built a NEPSE Share Calculator for Nepal’s Stock Traders – Here’s Why & How

For Nepali

If you've ever tried to calculate your NEPSE stock trade profits manually, you know how frustrating it can be. With varying brokerage rates, DP charges, and unclear taxes—it’s easy to make mistakes or waste time on spreadsheets.

As a solo dev and investor in Nepal, I wanted a tool that was simple, accurate, bilingual (English + नेपाली), and mobile-friendly.

So I built the NEPSE Share Calculator – a free web app to calculate your share trading costs and profits/losses instantly.

🧮 What It Does
NEPSE Share Calculator helps you:

✅ Calculate net profit/loss from share trades
✅ Understand how much tax, commission, and DP charges apply
✅ Choose between different broker rates (0.4%–0.6%)
✅ Get results in both English and Nepali
✅ Use it on mobile or desktop – no login required

🔧 Tech Stack
I kept the tech stack simple, fast, and scalable:

React + Vite for fast performance
Tailwind CSS for UI styling
React Router for routing
i18next for bilingual support (English/Nepali)
Hosted on Netlify for free, fast deployment
SEO-optimized with dynamic tags, canonical URLs and Schema Markup.

🌐 Why I Built This
Like many in Nepal, I invest occasionally in NEPSE-listed companies. But every time I sold shares, I’d have to:

Manually calculate broker commission
Guess the DP charge
Try to remember how tax is applied
Open my calculator app + Google Sheets 🤯

Instead of repeating that over and over, I decided to make a web app that anyone can use – even on mobile with slow internet.

🔤 Bilingual by Default
Nepal has a diverse user base. Some investors prefer English; others prefer Nepali. So the app defaults to English but supports full translation using a simple toggle (/ne route prefix). It even updates the meta title and schema for SEO in both languages.

✨ What Makes It Different?
Unlike other tools that feel outdated, over-complicated, or are hidden behind signups, this app is:

Free and open to all
Fast and lightweight
Optimized for both beginners and power users

🧪 What I Learned

i18n routing with SEO is trickier than I expected
Canonical and Open Graph tags matter more than we think
Most people value simplicity over features
React + Tailwind + Vite is a dream combo for side projects 🚀

I’d love your feedback, bug reports, or ideas for improvement. You can reach me on Twitter @GameeSarash or comment below.

If you find it useful, please consider sharing it with friends or family who trade stocks in Nepal!

💡 Future Plans

Add more calculators including Bonus, WACC, and more.
Allow tracking of multiple trades
Historical NEPSE data integration
Dark mode support 🌙

Thanks for reading – and to fellow developers: if you’ve ever wanted to solve a local problem with code, just start small. This project began as a weekend experiment and now helps thousands of people monthly.

Would love to hear what you’re building too!

Just Launched: Snow Days Calculator – Predict School Closures with Weather Data

Hari Kumar Thapa — Fri, 23 May 2025 16:49:54 +0000

Ever woken up wondering: “Will school be closed today because of snow?”

I did — and that’s why I built the Snow Days Calculator.

This simple app estimates the chance of a snow day based on live weather data and historical snowfall records.

It works for users in the US, Canada, Europe, and Australia — and it's totally free.

🚀 What is Snow Days Calculator?

Snow Days Calculator is a lightweight tool and Chrome extension that helps students, parents, and educators check the likelihood of school closures due to snow.

No more manually checking forecasts or guessing.

👉 Try the App: https://snowdayscalculator.net/

👉 Edge Extension: https://microsoftedge.microsoft.com/addons/detail/lemdhaigpgajbfhljgjclkhiokakbpcl

👉 ProductHunt: https://www.producthunt.com/posts/snow-days-calculator

👉 Chrome Extension: (Coming soon – under review)

🔍 Key Features

📍 ZIP code-based predictions
❄️ Snow day chance scoring
📊 Comparison with past snowfall data
🌍 Supports US, CA, EU, AUS
⚡ Mobile-friendly + fast
🔐 No sign-up, no tracking

🛠️ How It Works (Tech Stack)

I wanted to keep this light and fast, especially for students on mobile.

⚛️ React (Vite)
🎨 Tailwind CSS
🚀 Hosted on Netlify (free tier)

🧪 Sample Use Case

Say you live in Buffalo, NY or Calgary, Canada and snow is predicted tonight.

You open the app, enter your ZIP/postal code — and boom: It gives you a percentage score based on local snow forecasts and past data.

It’s quick, accurate (within limits), and updated in real time.

🧠 What’s Next?

I plan to add:

🏢 Office closure prediction (for employees/remote workers)
📩 Email alerts for snow day chances (opt-in)
🧠 Smarter prediction logic using AI
📆 Save favorite ZIP codes and set reminders

🗣️ Feedback Welcome!

I’d love to hear from early users and developers alike.

If you find this tool useful, give it a ⭐️, share it with friends, or leave a suggestion.

Let’s make snow day guessing a thing of the past!

Thanks for reading! 🙌
