About TilePilot & Our Calculation Method

A practical way to plan your tile purchase.

What we built

TilePilot is a free independent planning tool operated as part of RUNMU Tools. It helps homeowners and small renovation teams turn measurements into approximate tile pieces, whole boxes, and a simple budget. You can use it without signing up.

How every number is computed

Each zone's square-foot area equals width × length (or height), minus any user-entered openings. Repeat counts are then applied and the zones are summed. Metric measurements are converted to square feet for the material calculations.

Individual tile count is calculated by dividing the purchase planning area by the tile's face area and rounding up. Whole boxes are calculated by dividing the purchase planning area by the square feet printed on the box and rounding up. Actual tiles per box can differ due to nominal sizes and joints. Check the product carton.

Material prices are calculated using whole boxes, either at your entered price per box or using box coverage × your price per square foot. Optional labor is based on measured (not purchase) square feet. Material tax is applied to material price only. Labor taxes, local fees, adhesive, grout, trims, disposal, prep and waterproofing are not included.

What TilePilot is not

It does not create a precise piece-by-piece cut pattern, check building codes, replace material data sheets, verify quotes, or provide construction engineering. Treat every result as an estimate and check with your supplier or installer before ordering.
