📐 Area Coverage – Percentage Calculator

What It Does:
Calculates the percentage of a total area that has been covered with materials like tiles, paint, or grass.

Why It’s Important:
Helps you estimate how much of a surface is completed and whether you have enough materials left for the rest of the job.

Formula:
Area Coverage % = (Covered Area ÷ Total Area) × 100

Example:
You lay sod over 300 square feet of a 500 square foot yard:
(300 ÷ 500) × 100 = 60% coverage

This means 60% of your yard is covered, and 40% is still bare.

🧱 Material Wastage Percentage Calculator

What It Does:
Estimates how much material was wasted during construction, expressed as a percentage of total material used.

Why It’s Important:
Waste drives up costs and delays projects. Knowing the material wastage percentage helps reduce future losses and improve planning.

Formula:
Wastage % = (Wasted Material ÷ Total Material) × 100

Example:
If you bought 1,000 bricks but 70 broke during delivery or installation:
(70 ÷ 1,000) × 100 = 7% wastage

Aim to keep this percentage low to stay on budget.

🚧 Project Completion Percentage Calculator

What It Does:
Calculates how much of your project is finished, based on tasks completed, time elapsed, or money spent.

Why It’s Important:
Crucial for progress tracking, billing, and keeping clients or teams updated on timelines.

Formula (Tasks-Based):
Completion % = (Completed Tasks ÷ Total Tasks) × 100

Example:
You’ve finished 45 out of 120 tasks on a job site:
(45 ÷ 120) × 100 = 37.5% complete

You can also track by cost:
If you’ve spent $75,000 of a $200,000 budget:
(75,000 ÷ 200,000) × 100 = 37.5% complete (by budget)
