Maharashtra floor-area planning

FSI / FAR Calculator Maharashtra

Calculate simple floor-area capacity from plot area and an FSI/FAR value you have already verified. Then compare remaining development capacity and split the modeled area equally or with custom floor-by-floor allocation.

Calculate FSI / FAR capacity

Enter plot area and a verified FSI/FAR value, then use equal distribution or manually allocate a different area to each of up to 20 planning floors.

FSI calculation formula

Maximum simple floor area = Plot area × Verified FSI / FAR

The calculator applies only the ratio you enter. It does not automatically decide the legally permitted FSI for the site.

FSI and FAR are ratio-based planning measures used to relate total floor area to plot area. The exact regulatory treatment of different building components must be checked under the rules that apply to the property.

FSI calculation example

Plot area

1,000 sq ft

Example FSI

1.5

Simple floor-area result

1,500 sq ft

This 1.5 ratio is an arithmetic example only, not a statement that 1.5 FSI is legally available on any particular Maharashtra plot.

FSI vs FAR: what does the calculator do?

For this planning tool, FSI and FAR are handled as the ratio you enter between floor area and plot area. Search terminology can vary, so the same calculator supports users looking for FSI calculation, FAR calculation or Floor Area Ratio calculation.

Terminology and regulatory definitions should still be checked against the competent planning authority and the rules applicable to the land parcel.

Equal split or custom floor allocation

Use Equal split when you want a quick per-floor planning number. Switch to Custom floor allocation when the ground floor and upper floors need different modeled areas. The calculator totals the custom entries and compares them with the remaining modeled capacity.

Custom allocation is a feasibility helper, not a sanctioned building plan. Setbacks, coverage, height, fire, parking, access and other development controls can affect what can actually be approved.

The calculator does not determine permitted FSI

Verify the applicable FSI/FAR with the competent planning authority and current development-control rules for the exact property. Road width, zoning, reservations, land use, TDR or premium provisions and other site-specific rules can affect development potential.

From FSI capacity to construction planning

Once you have a verified development-capacity input, the next planning step may be to estimate layout feasibility, construction budget or core material quantities. These are separate calculations and should not be treated as approval outputs.

Frequently asked questions

How is FSI calculated?

FSI is a ratio of floor area to plot area. If you already know the verified permitted FSI for a property, a simple planning calculation is maximum floor area = plot area × FSI.

What is FAR and how is it calculated?

FAR means Floor Area Ratio. In a simple ratio calculation, floor area is divided by plot area. MahaMetric uses the FSI/FAR value you enter to calculate an indicative floor-area capacity.

What is an FSI calculation example?

For an illustrative example only, a 1,000 sq ft plot with an entered FSI of 1.5 gives 1,500 sq ft of simple floor-area capacity before considering any rule-specific inclusions, exclusions or approvals.

Can this calculator tell me the legally permitted FSI for my plot?

No. The tool does not decide the legally applicable FSI. Road width, zoning, reservations, land use, planning authority, premium or TDR provisions and other development-control rules can affect what is permitted.

Can I divide the calculated FSI across multiple floors?

Yes. The calculator can show an equal split or let you enter custom floor allocations across up to 20 planning floors and compare the total with the modeled capacity.
