    🧮 Cost Estimator PRO

    Estimate material costs across India, the US and the UK. Add multiple segments, apply mark-ups and wastage, toggle units, and generate a detailed report with KPIs and step-by-step calculations.

    Methodology & Assumptions

    Costs are computed per segment using the formula:
    Cost = Volume × Unit Rate × (1 + Markup/100) × (1 + Wastage/100). Unit Rates (per m³ or per yd³) are based on regional averages for 2025 and are approximate—users should verify against current market quotes. Changing the Unit System converts volumes (1 m³ = 1.308 yd³). Standards select default coefficients and note the relevant clause; values may auto-populate in future iterations. Currency values are displayed in the native currency of the selected region; convert manually if needed.
