# Pool Chlorine

> Calculate the amount of 65% calcium hypochlorite needed for a target free-chlorine increase. Enter pool volume and desired ppm change, then verify water chemistry and product directions before dosing.

## National default result

- **Typical:** $12
- **Planning range:** $10 to $14
- **Default quantity:** 1.5 10,000 gal treatment
- **Per unit:** $8 per 10,000 gal treatment
- **Components:** materials $12, labor $0, permits $0, disposal $0

The national default is a planning estimate, not a contractor quote. A ZIP changes the labor component using a metro or state OEWS wage multiplier; it does not change materials.

## Inputs

- **Pool volume:** default 15000 gal
- **Desired free-chlorine increase:** default 2 ppm

## Calculation

    material = baseline material rate × quantity × material index change × quality
    labor = baseline labor rate × quantity × labor index change × ZIP wage multiplier
    subtotal = material + labor + permit + disposal
    range = subtotal × documented low/high multipliers

Material index: PPIFIS, latest period 2026-07-01, change 2.69%.  
Labor index: PPIFIS, latest period 2026-07-01, change 2.69%.

## Main price drivers

- Project size and site access
- Material or finish tier
- Removal and disposal
- Ground, drainage, or structural conditions
- Permit rules and local labor availability

## Questions and direct answers

### What does this pool chlorine include?

The estimate separates materials, labor, permit, and disposal using the quantities shown. It excludes financing, hidden damage, and optional work not selected.

### How does the ZIP adjustment work?

ZIP is matched to a metro when available; otherwise a state wage factor is used. Only labor changes. Materials remain tied to national price indices.

### Is this a contractor quote?

No. It is a planning estimate. Confirm scope, code requirements, and price with licensed local contractors before committing funds.

### Why is the range wider than the typical cost?

The low and high multipliers capture ordinary variation in finish level, access, site conditions, and contractor availability.

### How current is the estimate?

The baseline is dated 2026-01-01. Index observations and their latest periods are displayed with every result.

### Can I use the result for a budget?

Use it as an early planning range and include contingency. A site-specific quote remains necessary for a committed budget.
