Vinyl liner bid calculator

How much to charge to replace a pool liner

A published “$2,999 for a 16×32” special prices the water. A residential vinyl liner is not the water. It is wall vinyl that does not scale with square feet, a hopper the coupon never counted, stairs that wrinkle, and often a new bead track. Matching the coupon on an 18×36 hopper oval is how a sold job becomes a two-day loss after the first wrinkle in the deep end.

The number a water-surface special cannot see

Take a 16×32 rectangle hopper, 20 mil solid, standard bead, no stairs. That is 96 lineal feet of wall and about 961 square feet of liner — on a 512 square-foot floor. The coupon says $2,999. Raise the same shop to an 18×36 oval with wedding-cake stairs and a patterned 27-mil sheet. The water is still “about an 18×36,” so the coupon barely moves. The liner did not scale that way: more wall, hopper extra, 85 extra square feet of stairs, and 14% pattern waste the 16×32 never had.

Put a new bead track on that oval. Track is lineal feet, not water surface. Overlap bead is coping work. Over-the-fence access is not “the same job plus a ladder.”

How to price it

1. Measure length and width. Rectangle is the product. Oval is the ellipse.
2. Count wall vinyl: perimeter times wall height (usually 42 inches). Add hopper extra. Add stairs. That sum is liner square feet.
3. Order square feet is liner times one plus waste. Patterned prints waste more.
4. Price mil (20 / 27 / 30), bead, track, cove, foam, a cover, pump-down, access, and the permit allowance.
5. Load the wage, add materials and mobilization, mark overhead on direct cost, then divide by one minus the target margin. The walk-away price is total cost.

The vinyl liner bid calculator does that arithmetic in the browser from your own hours and invoices. Starting mil rates, waste percents, and material rates are ballpark figures to replace, not a mill quote or a code table.

What this is not

This is not a building-code opinion, a permit, a construction specification, a manufacturer warranty, or an engineering stamp. Confirm the jurisdiction, the bead receiver, and a qualified professional before sending a price. The output is arithmetic on the numbers you typed.

Common questions

How much to charge to replace a pool liner?

Start from the water surface, count the liner square feet a water-surface special cannot see, then add hopper extra, stairs, bead work, track, extras, and the permit. A published $2,999 special only sees length times width.

Why do walls and stairs change the price?

A 16-by-32 rectangle is 96 lineal feet of wall and about 961 square feet of liner on a 512 square-foot floor. An 18-by-36 oval with a hopper and wedding-cake stairs adds vinyl and wrinkle time the 16-by-32 coupon never priced. Matching the coupon is how the oval loses money.

Is this a building-code calculation?

No. Mil rates, waste percents, and hours here are common starting points on residential bids. They are not a building-code opinion, a permit, a manufacturer warranty, or an engineering stamp.
