Insulation Cost Calculator
Build a transparent purchase-cost estimate from base quantity, waste, supplier price, delivery and other known project costs.
Cost method
Purchase quantity = base quantity × (1 + waste rate), rounded up to whole packages or boards. Material cost = whole purchase quantity × your supplier price. Delivery and other known costs are then added separately.
Use the quantity from the relevant insulation calculator when possible. Supplier prices, taxes, labour and delivery rules vary, so enter only costs you actually know.
