About this extension
KeyBid ROI Calculator — the rental-yield calculator for the Romanian real-estate market
Turn any Romanian property listing into an informed investment decision. KeyBid ROI Calculator shows you the estimated annual return on investment (ROI) for short-term rental operation — directly on the listing page of Romania's three largest property portals: Storia.ro, Imobiliare.ro and OLX.ro. No copy-pasting numbers, no spreadsheets, no leaving the page.
Browsing apartments for sale in Bucharest, Cluj-Napoca, Brașov, Constanța, Mamaia, Timișoara, Iași or Sibiu? Open a listing and instantly see the estimate: nightly rate, expected occupancy, annual revenue and ROI for short-term rental (Airbnb / Booking style operation).
━━━━━━━━━━━━━━━━━━
🆕 NEW IN VERSION 1.2.0
✅ Smart eligibility filter — the panel appears only on properties suitable for short-term rental: apartments, studios and penthouses FOR SALE. No irrelevant estimates on land plots, houses, commercial spaces or rental listings.
✅ Accurate floor-area (m²) extraction — the price-per-square-meter in the report is always computed from the listing's real usable surface.
✅ Property photo in the official PDF report — the report now embeds the analyzed listing's photo on all three supported portals.
✅ Minimal permissions, low resource usage.

⚡ HOW IT WORKS
━━━━━━━━━━━━━━━━━━
📊 THE FREE INSTANT ESTIMATE
The panel estimate is computed locally in your browser from the listing's public data:
• Sale price and usable floor area
• City and zone (dedicated multipliers for high-demand markets: Mamaia, Brașov, Cluj-Napoca, Bucharest and more)
• Property type (studio, 2–4 rooms, penthouse) and size
• Seasonality specific to the Romanian short-term rental market
• Typical operating costs for short-term rental management (35–40%)
It is an indicative estimate — ideal as a fast decision filter when comparing multiple listings.
━━━━━━━━━━━━━━━━━━
🧾 THE OFFICIAL KEYBID PDF REPORT
For due diligence, bank financing or investor presentations, generate the Official PDF Report — a complete investment analysis recalculated on KeyBid servers with real short-term rental market data:
• Real occupancy rates and nightly prices for the area, with month-by-month seasonality (verified market data)
• Estimated monthly revenue across a full year — not peak-season extrapolations
• Price per square meter computed from the real surface
• Profitability scenarios and operating-cost breakdown
• The analyzed property's photo and details
• Professional format, ready to present to a bank or investment partner
One-time payment per report, processed securely by Stripe (PCI DSS). No subscription, no account, no card data stored by us.

━━━━━━━━━━━━━━━━━━
🔒 PRIVACY & GDPR
• The add-on does NOT collect personal browsing data and does NOT track your activity.
• It only processes the public elements of the listing page (price, surface, title, public photo) to compute the estimate, locally in your browser.

• Compliant with Mozilla Add-on Policies and GDPR. Privacy policy available at KeyBid.ro.
━━━━━━━━━━━━━━━━━━
⚠ TRANSPARENCY
The ROI shown in the panel is an indicative estimate, not a guarantee of returns. Actual results depend on market conditions, final purchase price, management, season and achieved occupancy. For a full investment analysis we recommend the Official PDF Report, computed with real market data.
