Whether you're a real estate investor analyzing your next deal, a seller reviewing market trends, or an agent advising clients, quick and accurate financial insights are essential. That’s why I created a powerful, lightweight Property Investment Calculator SPA
— a set of standalone tools designed to simplify and speed up real estate financial calculations without relying on spreadsheets or external software.
Built entirely with Vue 3 and Tailwind CSS, this app is fully responsive, offline-ready, and requires no backend or server setup. It works right out of the box in any modern browser — on desktop or mobile.

🚀 Tools Included
This SPA offers five essential property investment tools:
- EMI Calculator: Estimate your monthly payments on a mortgage or property loan.
- ROI Calculator: Understand your return on investment based on net profit and total costs.
- Compound Interest Calculator: Forecast how your investment grows over time with compounding.
- Rental Yield Calculator: Determine the income potential of a rental property.
- Appreciation Forecast: Project the future value of your property using annual appreciation.
Each calculator includes a help popup that explains the formula being used, so even beginners can understand the financial logic behind the numbers. You can switch between calculators instantly using the tabbed navigation.
Why This?
Using spreadsheets usually involves:
- Typing numbers into multiple fields
- Remembering or rebuilding formulas (PMT, FV, NPV, etc.)
- Formatting cells
- Navigating dozens of tabs
In contrast, this tool offers a visual-first experience where sliders control the inputs, and the results update in real time — no typing, no tabbing, no recalculations. Want to see how increasing your interest rate by 0.5% affects your EMI? Just slide. Curious how 15 vs. 20 years of appreciation impacts property value? One motion, instant result.
This makes it ideal for:
- Quick evaluations during property viewings
- Pitching ROI to clients on-the-fly
- Making fast, informed decisions without opening Excel
Built for Usability
There’s no setup, no data entry clutter, and no need to download anything. Just visit the page and start calculating.
Plus, the tool works perfectly on phones, tablets, and desktops, so you can bring it into meetings, site visits, or virtual calls.
Whether you're a seasoned investor or a first-time buyer trying to make sense of financial terms, this app is your new favorite companion for property decision-making.
Try it now, share it with your clients or team, and let me know if you'd like more tools added!
