How the hard money loan calculator works out the loan and the flip
Hard money lenders size loans on the deal, not on your paycheck. Two limits apply, and the smaller one wins. Loan-to-Cost (LTC) caps the loan at a share of what you spend on the purchase and rehab. The After Repair Value (ARV) cap limits it to a share of what the property should be worth once renovated, typically around 65% to 75%.

Interest on a draw schedule
Most hard money loans are interest-only, with the principal due when you sell or refinance. The rehab money is usually held back and released in stages after an inspector confirms the work is done, a process set by the loan's Draw Schedule. If your lender charges interest only on funds drawn, each month's interest follows the balance actually outstanding:
Some lenders charge Dutch interest instead: interest on the full loan, including undrawn rehab funds, from the day you close. The calculator handles both; switch the "Interest on" control to compare them.
Profit and return on cash
Cash invested is everything that came out of your pocket: the down payment, closing costs, points and fees, any rehab the loan didn't cover, and the monthly interest and holding costs across the Holding Period. Selling costs come out of the sale proceeds along with the loan payoff.
Worked example: a $200,000 flip with a $340,000 ARV
An investor buys a house for $200,000, budgets $50,000 for the rehab and expects it to sell for $340,000. The lender offers 90% of cost up to 70% of ARV at 11% interest-only with 2 points and $1,500 of fees, and charges interest only on drawn funds. The rehab is drawn evenly over four months, and the investor expects to sell six months after buying.
The cost limit is 90% × $250,000 = $225,000 and the value limit is 70% × $340,000 = $238,000, so the loan is $225,000.00. The lender funds the full $50,000 rehab through draws and $175,000.00 of the purchase, leaving a $25,000.00 down payment. With closing costs, points and fees, the cash needed to close is $35,000.00.
Interest starts at $1,718.75 in the first month and rises to $2,062.50 once the rehab is fully drawn, totaling $11,687.50. After holding costs of $3,600.00 and selling costs of $27,200.00, the flip nets $37,512.50 on $50,287.50 of the investor's own money, a 74.6% return in six months.
Stress-testing the deal
Flips rarely go exactly to plan. Here is the same deal under four common surprises:
| Scenario | Total interest | Net profit | Return on cash |
|---|---|---|---|
| Plan as budgeted | $11,687.50 | $37,512.50 | 74.6% |
| Sale takes 4 months longer | $19,937.50 | $26,862.50 | 44.1% |
| ARV comes in 10% lower | $11,093.50 | $7,042.50 | 11.7% |
| Rehab runs 20% over budget | $12,045.00 | $26,975.00 | 52.1% |
| Dutch interest instead of draws | $12,375.00 | $36,825.00 | 72.2% |
A lower ARV does double damage: it cuts the sale price and, because the loan is capped at 70% of ARV, shrinks the loan so you bring more cash to closing. Dutch interest adds $687.50 here, which is why the interest basis is worth asking about before you sign.
The 70% rule and your maximum allowable offer
Before running the full numbers, many flippers screen a property with the 70% rule: offer no more than 70% of the after repair value, minus the cost of the rehab. The result is the maximum allowable offer. It is a rule of thumb among investors, not a lender requirement or a law; the 30% it holds back is meant to pay for the loan, holding the property, selling it, and a profit.

- After repair value, what the renovated property should sell for
- p
- The offer rule percentage, 70% by default (0.70)
- ext{rehab}
- The renovation budget
In the example, 70% of the $340,000.00 ARV less the $50,000.00 rehab is $188,000.00. The $200,000.00 price is $12,000.00 above it, so the deal fails this screen even though the full calculation shows $37,512.50 of profit. The calculator lets you change the percentage; a stricter or looser rule moves the offer by 1% of ARV for each point:
| Offer rule | Maximum allowable offer | Room under it at a $200,000 price |
|---|---|---|
| 65% | $171,000.00 | -$29,000.00 |
| 70% | $188,000.00 | -$12,000.00 |
| 75% | $205,000.00 | $5,000.00 |
A price above the maximum allowable offer doesn't mean the deal loses money, and one below it doesn't mean it makes money: the rule ignores your actual rate, points, holding time and selling costs. The profit and ROI figures above use all of them, so treat the rule as a first filter and the full calculation as the answer.
Hard money vs. a conventional loan, and when to use each
Hard money is expensive by design. You are paying for speed, flexibility and a lender willing to finance a property a conventional lender won't touch. Terms vary widely by lender and market, so treat the ranges below as typical rather than guaranteed.
| Hard money loan | Conventional loan | |
|---|---|---|
| Typical rate | Often 9% to 14%, interest-only | Market mortgage rates, fully amortizing |
| Upfront points | Commonly 1 to 4 points | Optional discount points |
| Term | About 6 to 24 months, then a balloon payment | 15 to 30 years |
| Approval based on | The property, ARV and your exit plan | Your income, credit and debt-to-income ratio |
| Property condition | Distressed and uninhabitable is fine | Generally must be livable |
| Rehab funding | Included, paid through a draw schedule | Rarely, outside specific renovation programs |
| Time to close | Days to a couple of weeks | Usually 30 days or more |
| Best for | Flips and short renovation projects | Long-term ownership |
Decisions that move the result most
- Buy right. The 70% rule, offering no more than 70% of ARV minus the rehab, leaves room for financing, holding and selling costs. Here it suggests a maximum offer of $188,000.00.
- Shorten the Holding Period. Every month adds interest and holding costs; line up contractors and permits before closing.
- Negotiate the interest basis and draw terms. Interest on drawn funds and fast draw inspections both cut your carrying cost.
- Plan the exit. If you will keep the property as a rental, check whether its rent supports a refinance with the DSCR loan calculator before you buy.
Where wholesaling fits
Wholesaling means putting a distressed property under contract and assigning that contract to a rehabber for a fee instead of buying it yourself. Wholesalers usually don't need a hard money loan, but they speak the same language: buyers judge a wholesale deal by its ARV, rehab estimate and the 70% rule, exactly as this calculator does. Running a buyer's numbers before you set your assignment fee shows whether the deal still works for them.
The bottom line
A hard money loan is a tool for speed, not a cheap way to borrow. In the example, the flip nets $37,512.50 on $50,287.50 of the investor's cash, a 74.6% return, after $11,687.50 of interest and $3,600.00 of holding costs.
Before you offer, test a lower ARV and a longer hold in the hard money loan calculator. If the deal only works when everything goes to plan, the price is too high.
Frequently asked questions
How much will a hard money lender lend on a flip?
Most hard money lenders lend the smaller of two amounts: a percentage of your total cost (purchase plus rehab), called loan-to-cost and often 80% to 90%, and a percentage of the after repair value, often 65% to 75%. For a $200,000 purchase with a $50,000 rehab and a $340,000 ARV, 90% of cost is $225,000 and 70% of ARV is $238,000, so the loan would be $225,000.00.
How is interest calculated on a hard money loan?
Hard money loans are usually interest-only. Each month you pay the annual rate divided by 12 times the balance outstanding, and the principal is repaid in a single balloon payment when you sell or refinance.
Is interest charged on undrawn funds?
It depends on the loan. If the lender charges interest only on drawn funds, you pay interest on the money released so far, so rehab draw interest starts small and grows as each draw is paid out. With Dutch interest you pay interest on the full loan, including rehab money not yet drawn, from the day you close. Ask the lender which applies and how quickly it inspects and releases draws, then switch the interest basis in the calculator to see the difference for your deal.
How are hard money points calculated?
Each point is 1% of the loan amount, paid at closing on top of the interest. How many points a lender charges varies with the lender, the loan and your track record, so ask for the points, rate and fees together in writing and compare offers on their total cost. The calculator adds hard money points to your cash to close and to the cost of the flip.
What does ARV mean in real estate?
ARV stands for after repair value: what the property should be worth once the planned renovation is finished. It is usually estimated from recent sales of comparable renovated homes nearby. Lenders cap hard money loans at a percentage of ARV, which is why they're sometimes called ARV loans: an ARV loan is sized on what the property will be worth, not what you pay for it. Investors use ARV to decide how much to offer.
What is the 70% rule in house flipping?
The 70% rule says to pay no more than 70% of the after repair value minus the rehab cost. With a $340,000 ARV and a $50,000 rehab, that is 0.70 × $340,000 − $50,000 = $188,000.00. The 30% margin is meant to cover financing, holding and selling costs and leave a profit. It is a screening rule; the full calculation above, a fix and flip calculator that includes the financing, is more reliable for a specific deal.
What is a maximum allowable offer?
A maximum allowable offer (MAO) is the most a flipper should pay for a property under their offer rule: the after repair value times the rule's percentage, minus the rehab cost. At the usual 70% rule, a $340,000 ARV and a $50,000 rehab give $188,000.00. It is a screening rule of thumb, not a lender limit.
How much cash do I need for a hard money loan?
You need the part of the purchase price the loan doesn't cover, plus closing costs, points and lender fees at closing, then enough to make the monthly interest payments and cover holding costs until you sell. In the example on this page that is $35,000.00 at closing and $50,287.50 in total over six months.
Can I use a hard money loan for wholesaling?
Most wholesalers don't, because assigning a purchase contract to another investor doesn't require buying the property. When a wholesaler does close on a property before reselling it, they typically use short-term transactional funding or their own cash rather than a renovation loan. Hard money is designed for buyers who will own and rehab the property.
