IHG Web Reward Night Calculator

WHAT IT DOES

IHG Web Reward Night Calculator reads your IHG One Rewards points balance and redemption rates from your account and booking pages and displays a floating reward night calculator showing how many free nights you can redeem with your current points. The badge shows your points balance, the number of free nights available, and the points per night redemption rate. The calculator automatically determines the best redemption rate based on your points balance and typical IHG property tiers. The extension tracks points history per month, storing each points balance change with a timestamp. When you reach enough points for 1, 3, 5, 10, 15, or 20 free nights, a desktop notification is triggered. The panel displays your current month's points history and changes over time.

WHERE IT RUNS

This extension works on all IHG pages at ihg.com and its subdomains, specifically on account pages and booking pages where points balance and redemption information are displayed. It runs on the main account page, the One Rewards dashboard, the booking page, the profile page, and any page displaying points information. The extension operates entirely within your browser and does not access IHG's servers directly—it reads only what is visible on the page you are viewing. It works alongside the free BotGentz extension, which provides the necessary scripting environment.

HOW TO USE

Install the extension, then navigate to ihg.com and log in to your account. The extension automatically creates a floating reward night calculator badge on the page. Click the extension's icon in your browser toolbar to open the settings panel. Use the "Show Overlay" / "Hide Overlay" button to toggle the badge visibility. The badge shows your points balance, free nights available, and redemption rate. Use the "Refresh" button to manually update the badge with the latest points information. The "Show redemption rates" toggle controls whether the points per night rate appears. The "Milestone notifications" toggle controls desktop notifications when you reach enough points for free nights. Adjust the overlay transparency using the opacity dropdown (70%, 82%, 92%, or 100%). Drag the badge by clicking and holding anywhere inside it. Resize it by dragging the bottom-right corner. Close the badge with the × button.

POINTS EXTRACTION WITH REDEMPTION RATE DETECTION AND NIGHT CALCULATION

Unlike simple balance display tools, this extension uses a multi-selector extraction engine to find points balance and redemption rates from IHG's varying page structures. It searches for points balance using multiple selector patterns (.points-balance, .reward-points, .balance-amount) and falls back to text parsing with number extraction. Redemption rates are extracted from rate selectors or inferred from typical IHG property tiers (10k, 15k, 20k, 25k, 30k, 35k, 40k, 50k, 60k points per night) based on the user's points balance. The number of free nights is calculated by dividing the points balance by the redemption rate. Monthly points history is stored as a key-value object where keys are year-month strings and values are arrays of points records with timestamps, limited to 20 entries per month. Milestone notifications trigger when the user has enough points for 1, 3, 5, 10, 15, or 20 free nights, with a once-per-day cooldown per milestone.

THE PANEL

The panel supports drag-to-move anywhere on the page. It remembers its position per site, so it stays where you placed it on ihg.com. Click the panel header to collapse it down to just the minimized bubble, or click the expand handle to show the full panel. The panel can be resized by dragging the bottom-right corner. Press the Escape key to close the expanded panel and return to the minimized state. All panel settings, including position, size, collapsed state, opacity, redemption rate visibility, notification preference, and monthly points history, are saved per site and persist across browsing sessions.

PLEASE NOTE

This extension requires the free BotGentz extension to be installed and active, as it provides the underlying DOM injection and script execution environment. IHG's website changes periodically, and points element structures, class names, and page layouts may be updated. When that happens, the extension may stop detecting points data until an update is released. The extension stores your overlay position, size, opacity, visibility, redemption rate preference, notification preference, and monthly points history locally in your browser's storage using GM_setValue. Points history is stored as a key-value object where keys are year-month strings and values are arrays of points records. The points balance displayed is read from the page—the extension does not access IHG's internal points data. Redemption rates are estimated based on typical IHG property tiers and may not reflect the actual rates for specific properties. Always verify with IHG directly for the most accurate reward night information. No data is ever sent to any server, and no personal information is collected. You can clear all stored settings at any time by clearing your browser data for ihg.com.
