How to use the House Painting Cost Estimator

Painting quotes vary wildly, and without your own estimate you cannot tell a fair price from an inflated one. This wall painting cost per square foot calculator gives you both sides of the job: the paint litres needed at a realistic 120 sq ft per litre per coat, and a total cost estimate using typical market rates — Rs 20 per sq ft for economy paint, 35 for standard and 60 for premium, all including labour. Walk into the negotiation with numbers, not guesses.

  1. Measure the wall area in square feet and enter it.
  2. Select the number of coats — 2 coats is the normal finish.
  3. Select the paint grade matching the quote you are checking.
  4. Click Calculate to see paint litres and the estimated total cost.
  5. Compare with the painter quote; big gaps are worth questioning.

Formula

Paint (litres) = area (sq ft) × coats ÷ 120. Total cost (Rs) = area × coats × rate (20 economy, 35 standard, 60 premium per sq ft).

Worked example

Painting 1,000 sq ft with 2 coats of standard paint: paint = 1,000 × 2 ÷ 120 = 16.7 litres (buy a 16-litre drum plus a 4-litre can). Cost = 1,000 × 2 × 35 = Rs 70,000 including labour.
