Real Estate Tower Project Cost Estimator

Set up towers, floors and flats to see the full project cost with land, construction trades, materials, stage-wise cash flow, finance and taxes. A measurement sheet is built from the same inputs, so it changes when you change the project, and you can edit it, add your own items and download it as CSV.

How the automatic sheet rows are sized

These are thumb rules for a first estimate. Replace them with drawing figures once the structural design is ready.

  • Floor plateFlats per floor × area per flat, plus common areas, converted to square metres and treated as a square plan for each tower.
  • Columns and beamsColumns on a grid about 6 m apart. Column size 0.30 × 0.45 m up to 4 floors, 0.45 × 0.45 m up to 12 floors and 0.60 × 0.60 m above that. Beams 0.30 m wide, 0.45 m deep, or 0.60 m deep in high-rise towers.
  • FoundationRaft under each tower, about 75 mm deep per floor, between 0.45 m and 2.0 m. PCC 100 mm under it. Excavation 1 m wider than the raft, deeper by 3.5 m for each basement level.
  • Slabs and stairs150 mm slab over the full floor plate on every floor, two stair flights per floor per tower, and a 200 mm lift-shaft wall for each lift when lifts are selected.
  • Walls and finishes230 mm outer walls around the plate, 115 mm inner walls at about 0.12 m per sq.m. of floor, plaster on both faces of inner walls, flooring across the plate and terrace waterproofing on the roof.

How the project cost is built

One base rate covers structure, finishes and building services. Everything else is added as its own line so you can see it.

Built-up = towers × floors × flats × area per flat × (1 + common areas)

Construction = built-up × base rate × location × building height

Facilities = selected items, several scaled by location

Site and utilities = 3% site works + 1.5% utility connections, on construction

Soft costs = 4% design, 3% approvals and RERA, 3% project management, 0.25% insurance, 0.5% administration, optional 3% marketing

Risk and finance = escalation, optional 18% GST, contingency and interest on the loan share

Total = land and legal + hard cost + soft costs + risk and finance

  • Base rate per sq.ft.Basic ₹2,600Standard ₹3,200Premium ₹4,500

Before you finalise a tower budget

Approvals shape both the design and the schedule of a multi-storey project.

  1. RERA registration

    Projects on land over 500 sq.m. or with more than eight apartments must be registered with the state RERA before advertising or selling. Plan the cost and time for registration and quarterly updates.

  2. Environmental clearance

    Building projects with 20,000 sq.m. or more of built-up area need prior environmental clearance. Check the built-up figure above against this limit early.

  3. Soil test, structure and fire

    Commission a soil investigation before fixing the foundation, and confirm fire safety requirements for high-rise buildings with the local fire authority, as limits and rules vary by state.

Questions

How is the measurement sheet generated?

It is built from your tower inputs. The calculator works out each tower's floor plate, assumes a roughly square plan with columns about 6 m apart, and lists excavation, PCC, raft, columns, beams, slabs, staircases, lift walls, masonry, plaster, flooring and terrace waterproofing with Nos, L, B and H/D in metres. Change towers, floors, flats, area or floor height and every automatic row updates.

Can I edit the sheet or add my own items?

Yes. Any number or description in the sheet can be changed. An edited row is marked Edited and stops following the calculator inputs until you press Restore. Use Add custom row for items the sheet does not generate, choosing cum, sq.m., running metre or numbers as the unit. Custom rows stay when you change the form.

How accurate are the sheet quantities?

They are first-pass quantities from thumb rules, useful for early budgeting and for checking a contractor's bill of quantities. Actual column sizes, raft depth, beam layout and wall lengths come from the structural and architectural drawings, so replace the automatic rows with drawing figures as soon as they are available.

What rate per sq.ft. does the estimate use?

The quality grade fills in a planning rate for structure, finishes and building services: ₹2,600 for Basic, ₹3,200 for Standard and ₹4,500 for Premium. You can type your own rate. The rate is then adjusted for location and for building height, because taller towers need heavier structure and more services.

How are materials worked out?

Cement, steel, sand, aggregate, bricks, tiles, paint and waterproofing are calculated from the measurement sheet using standard consumption per cum of concrete and masonry and per sq.m. of plaster and flooring. You can type local rates in the Materials tab. The rest of the construction cost covers labour, electrical and plumbing materials, doors, windows, fittings and contractor overheads.

What does the stage-wise breakdown show?

It places each cost in the stage where it is usually paid: land at the start, foundation in excavation, the RCC frame in superstructure, finishes and services later. Fees, contingency, taxes and interest are spread by duration. The cumulative figure shows how much of the budget is spent by the end of each stage, which helps plan funding.

How are interest and GST handled?

Interest is worked out on the loan share of cost at your interest rate, assuming half the loan is drawn on average over the build period. GST at 18% on contractor bills is off by default; switch it on if the project cannot claim input tax credit. Both appear as separate lines under All costs.

Is land cost included?

Only if you enter it. Land prices vary too much to guess, so the land field starts at zero. When filled, land is shown as its own line in the total and in the cost per flat.

How is the project duration worked out?

It starts from 10 months for planning, approvals and handover, adds 1.5 months per floor and 2 months per tower, and adjusts for quality: 0.95 for Basic, 1.0 for Standard and 1.1 for Premium, since better finishes take longer. The Timeline tab splits this into phases.

Can I compare two versions of the project?

Yes. Save one version as A, change anything such as floors, towers or quality, and save it as B. The Compare tab shows both side by side with the difference in total, cost per flat, area and duration.

Is my project information stored anywhere?

No. The calculator runs in your browser and loads no third-party scripts. It does not ask for company or contact details. Your inputs leave the page only if you copy the link, share on WhatsApp or download the CSV.
