Most budgets fail on the items nobody wrote down. This general cost calculator helps you list every component — materials, labour, fees, delivery, tax — and see the true total before you commit, not after the invoices arrive.
How to use this calculator
- List each cost item with its price and quantity.
- Add the easy-to-forget lines: delivery, installation, tax, disposal.
- Press calculate to see the full total and each item's share.
Total cost vs purchase price
A cheap option with high running costs often loses to a pricier one that is cheap to run. When comparing purchases, extend the list over the years you will own the item: energy, maintenance and repairs usually decide the winner.
Frequently asked questions
What costs do people forget most often?
Delivery and installation, taxes and fees, consumables, maintenance, and the cost of removing or disposing of the old item.
How much contingency should I add?
For home projects, 10 to 15% is a common buffer; for first-time or uncertain work, 20% is safer.
Can I use this for a business quote?
Yes. Enter your material and labour costs, then add your margin on top of the total to build a price.
