Convert RERA carpet area from square metres to square feet, estimate carpet area from built-up or super built-up area, and compare MOFA carpet area with RERA carpet area. You can also calculate loading percentage, price per sq.ft. and carpet area shortfall refund.
Preparing for the MahaRERA exam? Carpet area questions usually test Section 2(k), loading percentage, shortfall refund and Section 14(2).
| Search intent | Formula used | Use when |

| RERA carpet area to square feet converter | sq.m. x 10.7639 = sq.ft. | Your RERA document shows area in square metres. |
| How to calculate carpet area from built up area | built up area / (1 + built up loading %) | You know built up area but need RERA carpet estimate. |
| Super built up area to carpet area | super built up / (1 + loading %) | The builder quoted saleable or super built up area. |
| RERA carpet to built up area calculator | carpet area x (1 + built up loading %) | You know RERA carpet and want a built up estimate. |
| MOFA to RERA carpet area | MOFA carpet + internal wall area | You are comparing old Maharashtra/MOFA documents with RERA carpet disclosure. |
For MahaRERA carpet area calculation, start with Section 2(k): RERA carpet area is the net usable floor area plus internal partition walls, excluding external walls, service shafts, exclusive balcony/verandah area and exclusive open terrace area.
Section 2(k) of the RERA Act 2016 defines carpet area precisely: it is the net usable floor area of an apartment, including the area covered by internal partition walls, but excluding:
Internal staircases within the apartment, internal bathrooms, store rooms, and internal passage areas are included in carpet area. This is often misunderstood. Carpet area does not mean only the floor space where a carpet can be laid. It includes usable area inside the flat, including internal walls, bathrooms, and passages.
| Area Type | What It Includes | Typical Size vs Carpet |
|---|---|---|
| Carpet Area | Net usable area + internal walls (excl. external walls, balconies, shafts) | Base — smallest |
| Built-up Area | Carpet area + external walls + balconies/terraces | ~10-15% more than carpet |
| Super Built-up Area | Built-up area + proportionate share of common areas (lobbies, lifts, gym, pool etc.) | ~25-50% more than carpet |
Before RERA, developers quoted prices on super built-up area — the largest number. A 1,200 sq.ft. SBA flat might have only 780 sq.ft. of carpet area. Loading = (1200-780)/780 = 53.8%. You were paying for 1,200 sq.ft. but using only 780 sq.ft. exclusively.
RERA fixed this by mandating carpet area pricing. Now you can compare two flats with different loading percentages on a common basis. A flat priced at ₹8,000/sq.ft. on carpet area is directly comparable to another flat at ₹8,000/sq.ft. on carpet area — regardless of their loading percentages.
Under Section 14(2) of RERA, if the carpet area you receive at possession is less than what was promised in your agreement for sale, you are entitled to a proportionate refund. The refund is calculated at the rate per sq.ft. agreed in the sale agreement. Accepting possession does not waive this right — it survives even after you move in.
Example: Agreement says 900 sq.ft. at ₹9,000/sq.ft. Delivered: 850 sq.ft. Shortfall: 50 sq.ft. Refund: 50 × ₹9,000 = ₹4.5 lakh. File a complaint with MahaRERA if the promoter does not pay voluntarily.
Before accepting possession, measure the carpet area yourself or hire a licensed surveyor. Compare with the carpet area mentioned in your registered agreement for sale. If there is a discrepancy of more than a minor tolerance, document it in the possession letter. Do not sign the possession letter without noting any shortfall in writing.
On the MahaRERA portal, the promoter must disclose the carpet area of each apartment at registration. Check if the carpet area disclosed on the portal matches what is in your agreement — any discrepancy should be raised with MahaRERA before possession.
Section 2(k) definition, loading calculation, and the Section 14(2) shortfall remedy appear in the MahaRERA IBPS exam regularly.
