How do I estimate raw material and working capital needs for the report?

Short answer

Start from planned production volume, convert it into raw material quantities using the input needed per unit, and price it at current supplier quotes. Then follow the operating cycle: how long material is stored, how long finished goods wait, and how long customers take to pay, less the credit suppliers give. The net funding gap is your working capital need.

In more detail

Working capital is not a single number you pick; it falls out of how your business moves cash. Estimating it properly takes three passes.

For each product, list the materials, the quantity consumed per unit including normal wastage, and the supplier's quoted price. Multiply by projected output for each year, using the utilisation you have assumed. If the material is imported or seasonal, allow for the longer buying cycle and any price swings.

Decide how many weeks of raw material you must hold, based on supplier lead time and minimum order sizes. Add the time goods spend in production and then in finished stock before dispatch. Longer holding means more money is locked up.

Customers who pay after a delay create receivables, and each unit of delay raises the funding need. Suppliers who allow credit reduce it. Use the terms you actually negotiate, not the ones you hope for.

Total current assets minus the credit from suppliers and other current liabilities gives the gap. Part of it should come from your own funds, called margin, and the rest from a bank limit. Lenders usually expect some own contribution here.

A small fabrication unit

A workshop holds a few weeks of steel, spends a short period in production, keeps finished items for a week, and then waits several weeks for payment from customers. Suppliers give only brief credit. The stretch between paying for steel and receiving customer money is the period the working capital limit must cover.

Check that the sales you projected can be supported by this working capital. If the gap is far larger than the bank limit plus your funds, the sales figure needs revisiting.

Key points

Derive material needs from output volume and per-unit consumption, including normal wastage.
Holding period plus credit given to customers, less credit taken, defines the funding gap.
Use realistic payment terms you can evidence, not an optimistic case.
Part of the gap normally comes from your own funds, so show where they come from.
