You're planning a room upstairs, and the contractor has given you a price for casting the staircase. Then you think about the stone you'd like on the steps—and the railing still to be fitted. Does the quoted amount cover those too?
A staircase budget is easier to understand when you separate the concrete structure from the finish and railing. We'll follow one hypothetical staircase from its drawing to its material quantities, then add the costs of the specified work. That way, you can see what a casting quote includes and what still needs a budget.
In this one-storey example, the RCC structure costs ₹56,900. The subtotal reaches ₹84,300 with the stated finish and railing, or ₹92,730 with a separate 10% reserve. RCC means reinforced concrete. These quantities come from a hypothetical drawing, and the prices are illustrative. For your own staircase, use an approved design and local written quotes; this example explains the budget without choosing a safe staircase design for your house.
Start with the floor levels
The example drawing shows 3 m between finished floors, approximately 9.84 ft, with two flights, an intermediate landing and 20 risers. A riser is the vertical rise between steps; a tread is the horizontal surface you step on. Their counts are not always the same.
For this drawing, 3 m ÷ 20 = 0.15 m = 150 mm per riser. That calculation describes the example; it is not a recommended riser height for another house.
If you're considering a turn to save space, the step count alone won't tell you whether it works. The responsible designer needs to resolve the width, tread dimensions, headroom, landings and supports together. A change in direction or floor level needs a checked drawing. Even if a neighbour's staircase feels comfortable, copying its step count does not establish a suitable design for your home.
Measure the concrete beneath the steps too
The visible steps are only part of the concrete quantity. The sloping slab beneath them, called the waist slab, also needs to be measured, along with the landing and any specified concrete supports.
For a waist slab, use drawing width × actual slope length × specified thickness. Measure the steps and landings separately, taking care not to count the same concrete twice where the parts meet.
| Hypothetical takeoff | Quantity |
|---|---|
| Waist slabs and steps for both flights | 1.30 m³ |
| Intermediate landing | 0.30 m³ |
| Included concrete supports | 0.30 m³ |
| Concrete total | 1.90 m³ |
| Scheduled reinforcement | 220 kg |
| Purchase after whole-bar cutting plan | 230 kg |
| Concrete-contact formwork area | 25 m² |
These quantities are supplied for the worked example. They are not per-step rules you can apply to any staircase. Once you have the measurements from your drawing, the concrete calculator can help check the quantity; it does not choose a stair design.
Formwork—the temporary mould used to hold the concrete—is measured by the area in contact with it. To carry this example into the tool:
Open formwork with 25 m² of contact area
The link opens the formwork calculator with this example's 25 m² total contact area and no extra allowance. Check the sheet dimensions and enter your own rate. The tool calculates formwork quantities; concrete, steel and finishes remain separate parts of the budget.
Turn the bar schedule into a steel order
Next comes the reinforcement. The bar bending schedule, or BBS, lists the specified bar shapes, cut lengths and counts. Tata Steel's reinforcement documentation explains how a BBS is prepared from structural drawings.
In this example, the scheduled steel weighs 220 kg. A hypothetical cutting plan using whole stock-length bars brings the purchase quantity to 230 kg. The extra 10 kg comes from that particular cutting plan; it is not a fixed allowance for every staircase. If bends and laps are already included in the BBS, don't add them again.
At an assumed ₹65/kg, the steel purchase costs 230 × ₹65 = ₹14,950. Cutting, bending and tying labour are priced separately.
You can check known bar sizes and lengths in the rebar calculator. The roof steel guide explains the same process of turning a schedule into an order, but its roof quantities do not apply to this staircase.
Calculate cement from the approved mix
With the concrete volume known, you can calculate cement if the approved mix supplies a cement quantity per cubic metre. For example, if it specifies 320 kg cement per m³, then 1.90 × 320 = 608 kg. In 50 kg bags, that is 12.16 bags → 13 whole bags before placing losses.
The 320 kg input is only an assumption for this calculation, not a mix recommendation. Sand, aggregate and other ingredients must also follow the approved mix.
The concrete rate in the cost table below already covers cement, sand, aggregate and mixing, so don't add the cement cost again. Mortar for fixing the step finish belongs in the separate finish scope. If the stair and roof are cast together, also check that shared supports and landings appear in only one quantity takeoff.
Build up the structural cost
Now we can price the measured work. In these illustrative rates, formwork includes erection and removal. Cutting, bending and tying the reinforcement, along with concrete placing, have a separate labour allowance.
| Work | Example basis | Amount |
|---|---|---|
| Concrete supply | 1.90 m³ × ₹8,000 | ₹15,200 |
| Steel purchase | 230 kg × ₹65 | ₹14,950 |
| Formwork | 25 m² × ₹550 | ₹13,750 |
| Cutting, bending, tying and concrete placing | Labour allowance | ₹8,500 |
| Delivery, curing arrangements and small items | Allowance | ₹4,500 |
| Structure subtotal | — | ₹56,900 |
This ₹56,900 structure subtotal excludes underside plaster and paint, alterations to existing walls and applicable taxes. Before accepting a quote, check whether minimum delivery charges for a small concrete load or difficult site access would add to the stated allowances.
Add the step finish and railing
The structure is now priced, but the step finish and railing still need their own lines. Assume the finish to the steps and landing measures 80 sq ft, with material, fitting and the stated edges costing ₹150/sq ft. That gives 80 × ₹150 = ₹12,000.
For the railing, assume 7 m at ₹2,200/m, supplied and installed: 7 × ₹2,200 = ₹15,400. Adding both items gives the following budget:
| Defined scope | Amount |
|---|---|
| RCC structure | ₹56,900 |
| Step and landing finish | ₹12,000 |
| Railing and fitting | ₹15,400 |
| Subtotal | ₹84,300 |
| With a separate 10% reserve | ₹92,730 |
Check exactly what the finish measurement covers: does it include the vertical riser faces, the front edges of the steps (nosings) and the side edges? Twenty risers do not automatically mean an 80 sq ft finish order. The marble flooring guide explains how stone, fixing and polishing costs are separated; stair-specific edges and cutting still need to be described in your quote.
Compare quotes for the same staircase
Once the costs are separated, you can see which choices affect each line. If the budget needs adjusting, start by comparing specified stone and railing alternatives. A different finish changes its own cost without obscuring what the structure costs.
Changing the staircase arrangement is a different decision. Turning it to save room can affect heights, widths, landings and supports. Curved formwork or difficult access may also change the price even when the step count looks similar. Changes to waist-slab thickness, reinforcement, width or supports need the designer's revised approval.
Give each contractor the same drawing, BBS, finish specification and railing schedule. As the house budget guide explains, each major amount should identify the measured work it pays for. You can then see what needs to be added to a casting-only offer before comparing it with a quote that includes the finish and railing.
Questions that often come up
What does an RCC staircase cost?
In this one-storey example, the structure costs ₹56,900, rising to ₹84,300 with the stated step finish and railing. Your budget should use your approved drawing and local written quotes.
How much steel is required?
The example has 220 kg in the bar schedule and a 230 kg purchase based on a whole-bar cutting plan. Use your engineer's drawing and schedule to establish your actual requirement.
How much cement does the stair need?
If the approved mix specifies 320 kg/m³, the example's 1.90 m³ needs 608 kg: 12.16 bags, rounded up to 13 whole 50 kg bags before placing losses. Use the cement quantity specified in your own approved mix.
Is the railing included?
The ₹56,900 structure subtotal does not include it. This example adds ₹15,400 for the railing, supplied and installed, to reach the ₹84,300 subtotal with the step finish.
Can the cost be found by counting steps alone?
No. Floor levels, flights, widths, landings and supports also affect the quantities. Use the drawing to measure concrete and formwork, and the reinforcement schedule to establish the steel requirement.
