What extending the project adds
Every extra month of holding pushes your total cost higher, which is why investors who run tight timelines still fail when projects drag. Time is a cost you can only see if you count it.

What it does
Count every month the property bleeds money.
This calculator is for anyone who will hold a property without the planned income: a rehab before rent, a flip before resale, a vacancy between tenants, or a rental sitting listed for sale. It totals your monthly burn and then shows what three, six, and twelve extra months add, so you can see why time destroys thin deals.
What each major input means
- Loan payment / interest: your mortgage or hard-money interest, often the largest holding line.
- Taxes and insurance: usually paid annually but owed every month you own the property.
- Utilities, landscaping, security, maintenance: the property keeps costing money whether it is occupied or not.
How the calculation works
Simple math with an important lesson
The monthly holding cost is the sum of the monthly entries. The total is that monthly cost times the months you enter. The extension rows multiply the same monthly cost by three, six, and twelve additional months, and the bars show those totals relative to each other, so the visual matches the reality: holding costs never pause while you wait.
What the outputs mean
- Monthly holding cost is your burn rate; compare it to the project's expected profit or the rent you are missing.
- Total for your months is the real cost of the timeline you planned.
- The extension rows show how much delay adds, which is why flippers price timelines into every offer.
Important limitations
This tool does not include lost rent, which usually exceeds the holding costs themselves, or one-time costs of delays like loan extensions. If a project runs over, both of those stack on top of the numbers shown here.
Calculator FAQ
Common questions.
Direct answers about holding costs, what to include, and how to use the tool.
Why do holding costs matter so much in real estate investing?
Holding costs are the monthly burn while you own a property but are not collecting the planned income: during a rehab, between tenants, or while a flip waits for a buyer. Every extra month is money leaving the project, and the effect compounds across months.
What counts as a holding cost?
Anything you pay monthly while holding: loan payments or interest, property taxes, insurance, HOA dues, utilities, landscaping and pool service, security, maintenance, and other recurring expenses. Property taxes and insurance are often paid annually but accrue monthly.
How do I use this before buying?
Estimate how many months the project or vacancy will last, and compare that holding cost against the deal's projected profit or cash flow. If a three-month delay turns your profit negative, the deal has no margin for the delays that are normal in real estate.
Are these totals a guarantee of what holding will cost?
No. They are the sum of your entered costs over your entered months, for educational and planning purposes only, and are not financial, tax, legal, lending, or investment advice. Actual costs and timelines will differ.
