Documentation Overview

EstiMate

A mobile-first contractor cost estimation app that uses Monte Carlo simulation to provide probabilistic risk analysis for job quotes. Built natively for iOS (SwiftUI) and Android (Jetpack Compose).

Overview

EstiMate helps tradespeople and contractors move beyond single-point estimates to understand the range of likely costs and risks. Instead of guessing a single number, you input your estimates with uncertainty levels, and the app runs thousands of simulations to show you the probability distribution of total costs.

Key Value Propositions:

Offline-first, no login required
Sophisticated risk analysis on mobile (usually reserved for enterprise desktop software)
Helps contractors avoid under-quoting with statistically safe quote recommendations
Generates professional PDF quotes for clients

Features

Project Management - Create, save, and manage multiple project estimates
Line Items - Add materials, labor, subcontractors, and other costs
Risk Levels - 5-tier uncertainty system:
- Certain (±2%) - Fixed/contracted prices
- Low (±8%) - Known suppliers with stable pricing
- Medium (±15%) - Standard market variability
- High (±25%) - Volatile or uncertain costs
- Wild Guess (±40%) - Unknown scope items

Duration & Travel Estimation

Job Duration - Estimated days with complexity levels (Routine ±10% to Unknown Scope ±60%)
Labor Configuration - Hourly rates, hours per day, extra workers
Travel Costs - One-way travel time, traffic variability, site visits, mileage tracking
Correlation Modeling - Duration uncertainty automatically affects travel costs

Monte Carlo Simulation

1,000+ iterations with convergence detection
Skewed distribution toward overages (realistic for construction projects)
Percentile outputs: P10, P50, P80, P90, P95
Cost breakdown by category (Materials, Duration, Travel)
Standard deviation and confidence level calculations

Results & Export

Bell Curve Visualization - Color-coded histogram of cost distribution
Quote Recommendations - Conservative (P50), Recommended (P80), Safe (P90)

For each iteration (1,000 - 10,000):
    1. For each line item:
       - Generate random variance based on risk level
       - Apply skewed normal distribution (bias toward overages)
       - Calculate simulated cost

    2. For duration:
       - Generate random variance based on complexity
       - Calculate labor cost = days × hours × rate

    3. For travel:
       - Correlate visits with duration uncertainty
       - Generate traffic variance
       - Calculate travel time + mileage costs

    4. Sum all costs + profit margin

Calculate statistics from all iterations
Check for convergence (P80 standard error < 0.5%)
