Plain-English explanation
Lenders typically require a 5–10% contingency reserve on top of the construction budget so unforeseen issues don't stall the build.
Why it matters
It's a buffer against material spikes, weather delays, and change orders.

A real-world example
A $500,000 build includes a 10% ($50,000) contingency reserve; a foundation surprise draws $18,000 from it, and the build continues on schedule.
Educational and illustrative only
A common misunderstanding
A contingency reserve is not extra profit for the builder — it's set aside specifically to cover unexpected cost overruns.
