Time Estimate vs Actual Calculator

WHAT IT DOES Time Estimate vs Actual Calculator is a floating calculator panel that tracks and compares estimated vs actual time for tasks. Enter task estimates and actual times — the panel calculates variance (estimate minus actual), over/under percentage, and an accuracy score (estimate/actual × 100). Aggregates totals across multiple tasks and color-codes results: green for under-estimated (good), yellow for on-target, red for over-estimated (needs improvement). Helps teams improve estimation accuracy over time. WHERE IT RUNS This script runs on any website you visit. It reads only the page you are looking at, never other tabs, bookmarks, or browser data. All data stays in your browser — nothing is sent anywhere. HOW TO USE Click the Time Estimate vs Actual Calculator panel button in the BotGentz extension toolbar. The panel appears at the edge of the page. Enter a task name, estimated time (hours), and actual time (hours), then click "Add Task". The panel shows a list of all tasks with individual variance, and a summary section with totals, variance, over/under percentage, and accuracy score. Use "Clear All" to reset, or "Copy Summary" to copy the full analysis to your clipboard. Entries persist across pages. TECHNICAL MECHANISM The calculator stores tasks in a local array. For each task, variance = estimate - actual (positive = under-estimated, negative = over-estimated). Over/under % = variance / estimate × 100. Accuracy score = estimate / actual × 100 (where 100% = perfect estimation). Totals are summed across all tasks. Color coding: green for variance > 0.5h (under-estimated), yellow for variance within ±0.5h, red for variance < -0.5h (over-estimated). All calculations run client-side in pure JavaScript. Data persists using GM_setValue. THE PANEL The panel is a floating overlay that you can drag anywhere on the screen by its header. It remembers its position per site so it reappears where you left it. The panel can be collapsed into a small handle to get it out of the way, and snapped to the edge of the page. It can be resized to fit your workflow. Press Escape to close the panel. PLEASE NOTE This script requires the free BotGentz extension to run. All data stays in your browser — nothing is transmitted or shared. The panel works on any website. The calculator is for estimation analysis purposes only. Sites change — the script may need updates to match new site structures.
