The formula

Know exactly what the calculator is doing.

Total holding cost = hold months x monthly recurring cost + delay days x daily recurring cost

The daily figure annualizes recurring costs for scenario planning. Material bills should still be calculated from their actual billing periods and terms.

A durable workflow

Use the result as a decision aid, not a verdict.

01

Build the complete calendar

Include permit, construction, punch, listing, market, contract, and closing time.

02

Separate recurring costs

Use actual loan, tax, insurance, utility, association, and service figures.

03

Price the downside

Extend every cost that continues and add event-specific fees separately.

Important limits

What this calculation cannot know.

  • Listing the property or accepting an offer does not stop carrying cost.
  • Use loan documents for interest, maturity, minimum interest, and extension calculations.
  • Do not count tax, insurance, or principal twice when payments include escrow.

Common questions

Understand the terms before using the output.

What are holding costs in a house flip?

They are financing and ownership costs that continue while the project is held, such as interest, property tax, insurance, utilities, association charges, security, and property care.

When should the hold period end?

Usually when sale or refinance funds close and the relevant obligations stop, not when renovation or listing ends.

How is daily carrying cost calculated?

This calculator converts annual and monthly recurring costs into an average daily rate for schedule sensitivity.

Does loan principal count?

Principal changes cash flow and payoff but should not automatically be counted as an economic cost in addition to the loan payoff.

Should delay fees be included?

Yes. Add extension, remobilization, equipment, permit, storage, or other event-specific costs separately from recurring daily cost.
