What is Construction Cost Calculator?
Construction Cost Calculator helps you estimate construction spending from floor area and a cost-per-area rate.
The main result is construction budget. The formula, example and assumptions below explain how to interpret it.
How to use Construction Cost Calculator
Use the example to get familiar with the form, then enter your own figures. Any rates in the example are illustrative. Check the field labels and units before calculating.
- Gather total constructed floor area (ft²), construction cost per square foot (₹), design, approvals and other costs (₹) and contingency (%). Use values from the same situation or reporting period.
- Replace the example total constructed floor area with your own value, then complete the other fields. Check the displayed units.
- Select Calculate and read construction budget. Change one input and calculate again to compare a second scenario. Reset restores the original example.
- Enter total constructed floor area in ft², at least 0. Decimals are accepted.
- Enter construction cost per square foot in ₹, at least 0. Decimals are accepted.
- Enter design, approvals and other costs in ₹, at least 0. Decimals are accepted.
- Enter contingency in %, at least 0 and at most 100. Decimals are accepted.
Construction Cost Calculator: a worked example
With the inputs below, the result is ₹34,65,000 (construction budget). Follow the example, then replace these illustrative values with your own.
| Input or output | Example value |
|---|---|
| Total constructed floor area (ft²) | 1,500 ft² |
| Construction cost per square foot (₹) | ₹2,000 |
| Design, approvals and other costs (₹) | ₹1,50,000 |
| Contingency (%) | 10 % |
| Construction budget | ₹34,65,000 |
Understanding the Construction Cost result
The main output is construction budget, expressed in ₹. It applies to the inputs and operation you selected.
Displayed results use a readable number of decimal places. When checking a result by hand, keep extra precision until the last step. To compare scenarios, change one input at a time and keep the others fixed.
Construction Cost Calculator: assumptions and common mistakes
A useful estimate starts with the right inputs. Check the following assumptions and limits before applying the result to your situation.
- Keep dimensions in the displayed units and distinguish usable area from built-up area. Material estimates need a suitable allowance for site conditions and waste.
