Force Majeure Delay Cost Calculator
When delays are excused under force majeure clauses, GC owes no LD but owner still loses rent and carries extra cost. This calculator sizes that pure loss.
Total owner cost
$135,000
Lost rent
$90,000
Extra carry
$45,000
How the math works
Force majeure delay cost = lost rent + extra carry × days. No LD relief from GC.
Insurance protections exist: business interruption, builder's risk, and delay-in-completion policies can cover part of force majeure loss. Confirm coverage with broker.
How to Use
- Enter delay days.
- Enter lost daily rent.
- Enter daily carry cost.
- Read total force majeure cost to owner.
Frequently Asked Questions
What qualifies as force majeure?
Typically: acts of God, war, terrorism, government action, strikes. Weather sometimes included but contentious. COVID triggered massive force majeure claims in 2020-2021.
Can I limit force majeure?
Yes — narrow definitions, notice requirements, and mitigation obligations all reduce GC's ability to claim. Institutional owners strip weather, routine government action, and sub-vendor delays from FM.
Who bears the cost?
Owner. Under standard AIA contract, force majeure = extension of time but no compensation. Owner loses rent + carry but can't claim from GC.
