Under-stair storage panel cost planner

Estimate rectangular storage blanks beneath an existing stair. Sloped pieces require measured geometry: a rectangle allowance does not describe the final angled cut.

Sheet material and measured parts prepared for a cutting layout

Estimate rectangular blank stock and cost

Editable demonstration: 4 rectangular blank pieces, 1100 × 550 mm. The sheet price is illustrative, not a supplier quote. Replace every value with your own measurements.

1. Finished panel
2. Sheet stock

Leave unchecked when grain must follow part length. Kerf and trim are checked in the later layout, not this area estimate.

3. Optional labor allowance

No login. Inputs are used in this page and are not saved as a project.

Before measuring this panel group

  1. Template the existing slope and check access, services and door swing.
  2. Use bounding rectangles for this allowance; retain the angled offcut as waste until proven reusable.
  3. Keep the storage design independent of the stair structure and required clearances.

Not included: Angled cut geometry, doors, hardware, services and structural stair work are excluded.

Build the checked parts list in CutList

Use CutList for the rectangular sheet blanks. Mark and verify the angled finishing cuts separately from the sheet layout.

Confirm actual stock thickness, sheet dimensions, saw kerf, usable edges and permitted rotation. An allowance cannot establish a cutting order. Review the generated layout before ordering material, and keep the approved project available in the workshop.

If the job also includes a stair

Keep stair geometry in Stringer

Use Stringer for riser options, stair geometry, stringer diagrams and a stair cut-sheet PDF. The rectangular storage allowance above does not calculate a stair or verify its structure.

See Stringer for this part of the job

Furniture

Bookshelf

Budget the repeated shelves before pricing the complete bookcase. Shelf depth and grain direction often decide whether an apparently spare strip is usable.

Cabinet shop

Kitchen cabinet

Start with cabinet side panels, then build up the remaining stock groups. Carcass panels and thin backs cannot share one purchasing calculation simply because both are plywood.

Fitted furniture

Wardrobe

Check tall gables against available sheet length before estimating cost. A low area total is of little help if a full-height panel cannot fit the selected stock.
