Painting Cost Calculator
Estimate house painting cost from room size, coats, paint coverage and your own paint, putty and labour rates. See litres to buy, cost per sq ft and GST.
यहाँ से शुरू करें
- क्या भरें
- कमरे की लंबाई, चौड़ाई, दीवार की ऊँचाई, छोड़ने वाले दरवाजे-खिड़की का क्षेत्र, कोट, डिब्बे पर लिखी कवरेज और अपनी पेंट, तैयारी, मजदूरी व GST दरें भरें।
- नतीजे का मतलब
- कुल = पूरे लीटर में पेंट + पेंट योग्य क्षेत्र पर तैयारी और मजदूरी + GST। प्रति वर्ग फुट लागत इसे पेंट योग्य क्षेत्र से भाग देकर मिलती है।
उदाहरण और सीमाएँ देखें
- आसान उदाहरण
- 12 × 10 फुट का कमरा, 10 फुट दीवारें, छत सहित और 40 वर्ग फुट दरवाजे-खिड़की: 520 वर्ग फुट; 100 वर्ग फुट प्रति लीटर पर दो कोट में 10.4 लीटर, यानी 11 लीटर खरीदें।
- ध्यान रखें
- हर दर आपकी अपनी है; कोई शहर-वार कीमत नहीं। असली दीवारें डिब्बे पर लिखी मात्रा से ज्यादा पेंट सोख सकती हैं और डिब्बे तय साइज में आते हैं।

आपके आँकड़ों का मतलब
All-in, this job costs ₹37 per paintable sq ft.
520 sq ft of paintable surface for ₹19,234 including GST. Ask contractors to quote on the same area so the rates are comparable.
You need 10.4 L for 2 coat(s); buying 11 L leaves about 0.6 L spare.
Keep the leftover from the same batch for touch-ups, since a later batch can differ slightly in shade.
One coat fewer would save ₹1,770 in paint and GST.
Labour and prep rates stay the same here because you entered them per sq ft. Dropping a coat usually only works when the new colour is close to the old one.
Labour and prep are 80% of the cost before GST.
With your numbers, the labour and putty/primer rates affect the total more than the paint price does. Negotiate those rates first.

अपनी गणना समझें
This painting cost calculator turns your room measurements into a paintable area, the litres of paint to buy and a full job cost. You enter the room length, width and wall height, the door and window area to skip, whether the ceiling is included, the number of coats and the coverage printed on the paint tin. Then you add your own paint price per litre, primer and putty rate, labour rate per sq ft and GST. The calculator has no built-in city rates: every price comes from you, so the estimate matches the quotes you actually have.
Painting Cost Calculator क्यों उपयोग करें
Painting quotes are usually given per sq ft, but contractors measure area differently and some fold putty, primer and paint into one figure. Working out the paintable area yourself lets you check whether a quote is measured fairly, see how many litres you really need and separate material from labour. Because the coverage, coats and every rate are inputs, you can compare two paint brands, two contractors or a walls-only job against walls plus ceiling in a few seconds, and see the effect of each choice on the total.
Painting Cost Calculator कैसे उपयोग करें
- 1
Measure the room
Enter length, width and wall height in feet, and the number of rooms with the same size.
- 2
Subtract openings
Add up door and window area for one room and enter it so those surfaces are not painted or charged.
- 3
Enter paint details
Choose the number of coats and enter coverage per litre per coat from the tin, plus the price per litre.
- 4
Add prep, labour and GST
Enter the primer and putty rate, the labour rate per sq ft and the GST rate from your quote.
- 5
Review the breakdown
Check litres to buy, paint, prep and labour cost, GST and the cost per sq ft.
उदाहरण
One 12 × 10 ft bedroom, walls and ceiling
A 12 ft × 10 ft room with 10 ft walls, 40 sq ft of doors and windows, ceiling included, two coats, paint covering 100 sq ft per litre per coat at ₹300 a litre, ₹10 per sq ft prep, ₹15 per sq ft labour and 18% GST. All rates are example inputs.
- Walls: 2 × (12 + 10) × 10 − 40
- 400 sq ft
- Ceiling: 12 × 10
- 120 sq ft
- Paint: 520 × 2 ÷ 100 = 10.4 L, rounded up
- 11 L = ₹3,300
- Prep: 520 × ₹10
- ₹5,200
- Labour: 520 × ₹15
- ₹7,800
- GST at 18% on ₹16,300
- ₹2,934
- Total
- ₹19,234 (about ₹37 per sq ft)
Here prep and labour are more than three-quarters of the cost before GST, so those two rates matter more than the paint price.
इसकी गणना कैसे होती है
Paintable wall area per room is 2 × (length + width) × height − doors and windows. If you include the ceiling, length × width is added. Both are multiplied by the number of identical rooms.
Paint needed is paintable area × coats ÷ coverage per litre, rounded up to whole litres and priced at your paint rate. Prep and labour are your per-sq-ft rates multiplied by the paintable area.
Total is (paint + prep + labour) × (1 + GST%), and cost per sq ft is that total divided by the paintable area.
मान्यताएँ और सीमाएँ
- All prices, coverage and GST are user inputs; the calculator contains no city or brand rates.
- Rooms are treated as rectangles with identical size; enter different rooms separately and add the totals.
- Paint is priced on whole litres, not on tin pack sizes, so your actual purchase may be slightly higher.
- Prep and labour are charged on paintable area and do not change with the number of coats.
- Repairs such as damp treatment, crack filling beyond normal putty, scaffolding and furniture moving are not included.
अक्सर पूछे जाने वाले प्रश्न
How is the paintable wall area calculated?
For each room, the four walls are 2 × (length + width) × height. Door and window area is subtracted, and the ceiling (length × width) is added if you include it. The result is multiplied by the number of identical rooms.
How many litres of paint do I need?
Multiply the paintable area by the number of coats and divide by the coverage per litre printed on the tin. The calculator rounds this up to whole litres. Rough or absorbent walls usually get less coverage than the label says.
Does the calculator use painting rates for my city?
No. There are no city presets or built-in prices. You enter the paint price, prep rate, labour rate and GST from your own quotes or shop visits, and the defaults are only example numbers.
Should primer and putty be entered separately?
Enter them as a per-sq-ft prep rate if your contractor quotes them separately. If the labour rate already includes putty and primer, enter 0 for prep so they are not counted twice.
Why does one coat fewer not reduce labour cost?
Labour is entered per sq ft of surface, so it does not change with coats in this model. If your contractor charges per coat, adjust the labour rate you enter.
Is GST added to paint bought separately?
The GST rate you enter is applied to paint, prep and labour together. If your paint price already includes GST, enter 0 for GST or use a rate that applies only to the part of the quote that excludes it.
अंतिम बात
Measure each room once, enter the rates from your shortlisted contractor and paint brand, and use the cost per sq ft to compare quotes. If two quotes differ, check the paintable area and whether putty and primer are included before comparing the totals. For a whole-home budget, add this figure to your flooring and other work in the home renovation cost calculator.
