About the Renovation Budget Calculator
What is the Renovation Budget Calculator?
Renovation costs depend mostly on scope: repainting costs a few hundred rupees per sq ft of floor, while a full renovation with new wiring and plumbing costs several times more. This renovation budget calculator builds the budget from these blocks.
Choose the scope for the general work, then add the modular kitchen, the number of bathrooms to redo and a contingency percentage.
How to use the Renovation Budget Calculator
- Carpet Area (sq ft) (sample: 1,000)
- Scope of Work (sample: Moderate – flooring, false ceiling, wardrobes (₹1,200/sq ft))
- Modular Kitchen Budget (₹) (sample: 3,50,000)
- Bathrooms to Redo (sample: 2)
- Cost per Bathroom (₹) (sample: 1,50,000)
- Contingency (%) (sample: 15)
- Press Plan Renovation Budget (results also refresh as you type). The result card shows the Total Renovation Budget, along with General work, Kitchen, Bathrooms and Contingency buffer.
Formula used
Budget = (Area × Scope rate + Kitchen + Bathrooms × Cost each) × (1 + Contingency %)
- Scope rate = paint ₹30, refresh ₹500, moderate ₹1,200, full ₹2,200 per sq ft of carpet area
Rates are indicative for Indian metros in 2025; get at least three itemised quotes.

Tips for using the Renovation Budget Calculator
- Fix plumbing and wiring before cosmetic work; redoing it later costs far more.
- A home improvement loan or top-up loan is usually cheaper than a personal loan.
- Society approval may be needed for structural or façade changes.
