About this calculator
Turn start and finish times into total crew hours and labour cost, ready to drop into a job.

Tips from the trade
- Track actual hours against quoted hours on every job. It is the fastest way to sharpen your pricing.
Results are estimates for planning and pricing. Check quantities against your drawings, the manufacturer’s data and SANS 10400 (the National Building Regulations) and your local municipality before ordering.
