- Contingency %

All calculation runs locally in your browser; results update as you type and include the substituted working.

## Turn One Rate Into a Whole-Build Budget

Most build budgets start from a single number: the local rate per square meter. AiLoveKit's **construction cost calculator** multiplies your covered area by that rate, adds contingency, and shows the math - a fast sanity check before you commission detailed quotes.

## Using the Calculator Well

- **Collect 2 to 3 local rates** - grey structure and finished, separately.

- **Multiply by covered area** - every storey counts.

- **Add contingency** - 5 to 15% depending on risk.

## Frequently Asked Questions

**What does the rate per m² cover?**

Whatever your quote covers - typically structure plus standard finishes. Confirm whether plumbing, electrical and fixtures are included before comparing rates.

**Why add contingency?**

Ground conditions, design changes and price movement routinely add 5 to 15% to self-build budgets. 10% is a sensible default.

**Is this a real-time market price?**

No. The rate is entered by you and any reference figures we show are indicative planning data, not live market quotes.
