Fixed price vs allowance: what homeowners should know

Allowances are the most common source of “surprise” costs — and also the fairest way to price things nobody can see yet. Here's how to read them.

A fixed-price item is a set amount for a defined piece of work: the contractor takes the risk if it costs them more. An allowance is a budgeted amount for something that can't be defined yet — a product you haven't chosen, or a condition nobody can see until the ground is open. If the real cost is higher, you pay the difference; if it's lower, you should get a credit.

Fixed price puts the risk on the contractor; an allowance shares it with you.

When allowances are fair

  • Selections not yet made — light fixtures, a paver you're still choosing.
  • Hidden conditions — what's under an old patio, rock or roots in an excavation, rot behind a ledger board.
  • Quantities that depend on discovery — extra fill or base if the soil is poor.

When to push back

  • The allowance is unrealistically low — it makes the total look cheap, then the real cost lands later.
  • The work could be defined now — a contractor who's seen the site should be able to price standard items.
  • There's no rate for overages — ask how extra quantities will be priced (per cubic yard, per hour).
  • There's no credit if it comes in under.
