INSTALLATION PLANNING
Generator installation quote comparison tool
Put two to four written proposals on the same worksheet. Separate prices already included from required extras, then see the known amount and the questions that still prevent a fair comparison.
Start with the installer planning guide and use the generator quote checklist to request matching scope. This tool does not check contractor credentials or recommend a winning bid.
Before entering prices
- Use USD, digits and up to two decimals; omit commas and currency symbols. No example prices are prefilled.
- Included allowance: a provisional amount already inside the quoted total. Enter the sum of all such allowances. If you know the final cost of all the same items, enter that sum as the replacement. Do not enter just the overrun.
- Required extras: prices outside the quoted total. Enter their combined confirmed amount once. Never repeat an included allowance or its replacement here. Leave unknown prices blank; enter 0 only when confirmed none.
- Blank allowance means you have not confirmed whether allowances exist. A positive included allowance with a blank final cost stays provisional. Scope selections record coverage; they do not add money.
Privacy: calculations run in your browser. No lead submission, account, analytics on this page, or automatic storage of your entries. Clear removes the worksheet; export creates a file only when you choose it. Do not enter private contact details.
Comparison results
Comparable known amount is not a final installed price. Formula: quoted total − included allowance being replaced + confirmed final allowance cost + known required extras. If the final allowance cost is unknown, keep the original provisional allowance. Unknown extras are omitted from arithmetic, not confirmed as zero.
Rows stay in entry order; there is no cheapest ranking. Even with every field resolved, confirm the same load plan, equipment specification, fuel work, taxes, warranty, payment schedule and exclusions before deciding. Read why installation quotes vary for the differences a total cannot explain.
| Proposal | Quoted total | Allowance adjustment | Known required extras | Comparable known amount | Status and questions to ask |

Turn missing scope into a written answer
Ask each bidder whether every required item is included, separately priced, excluded or not needed for your site. “Included” may still contain an allowance: obtain a firm amount or a documented change-order basis. If only some allowance items have final prices, leave the combined final field blank until all are confirmed.
A resolved worksheet is not a site assessment, code review or contractor endorsement. Review the unverified directory status and verification limits before treating a provider listing as evidence of licensing, insurance or suitability. Keep original proposals and written clarifications alongside your export.
Amounts: 0–999999999.99 USD. Blank means unknown; zero means confirmed none. Final allowance is a replacement, not an extra.
