What Goes Into a Private Money Loan Cost Calculation
A private money loan is short-term financing from a private investor or lender, secured by real estate, that is priced on the property's equity rather than on your credit score.
Here is the core problem most borrowers run into. They focus on the interest rate and ignore everything else.
Below, we break down each input, show the formulas, and run a full worked example so you can price a deal yourself.
Itemized Fees: Points, Origination, and Closing Costs
Fees are where private money loans get expensive, so start here. Most private lenders charge a mix of the following:
- Points: a percentage of the loan amount paid upfront. Two points on a $300,000 loan is $6,000.
- Origination fee: a separate lender charge for processing the file, often quoted as a flat fee or a percentage.
- Closing costs: title, escrow, appraisal, and recording fees paid to third parties.
- Cash to close: the total you bring to the table, including your down payment and rehab reserves.
A common mistake is treating points as the only fee. In practice, origination and third-party closing costs can add meaningfully to your cash-to-close figure. Ask every lender for a written, itemized list before you compare offers.
Interest Rate and Loan Term Inputs
Two numbers drive the interest portion of your cost: the annual interest rate and the loan term. Private money loans usually carry higher rates than bank loans because they are fast, equity-based, and short-term.
The loan term is the repayment period, often measured in months rather than years. A shorter term means less total interest but a bigger monthly obligation. A longer term lowers the monthly payment but raises total interest.
Using a Private Money Loan Calculator for Accurate Estimates
A private money loan calculator is a tool that takes your loan amount, rate, term, and fee inputs and returns your monthly payment, total interest, and cash to close. It removes arithmetic errors and lets you compare scenarios in minutes.
You can build a simple version in a spreadsheet. The key is knowing which inputs to enter and how to read the output.
Enter Loan Details and Read the Output
Work through the inputs in this order:
- Loan amount: the principal you are borrowing, based on purchase price minus your down payment.
- Interest rate: the annual interest rate quoted by the lender.
- Loan term: the repayment period in months.
- Points and fees: entered as a percentage or dollar amount.
- Repayment structure: interest-only or principal and interest.
Then read the output carefully:
- Monthly interest: loan amount × (annual rate ÷ 12).
- Total interest: monthly interest × number of months.
- Cash to close: down payment + points + origination + closing costs.
Hard Money Loan Points and Fees: What Lenders Charge
Hard money loan points and fees are the upfront charges a lender takes at closing, and they are the single biggest swing factor in your all-in cost. Points are quoted as a percentage of the loan amount, so a larger loan means a larger dollar charge even at the same point level.
Watch for these traps:
- Points quoted on the funded balance rather than the loan commitment can shift the math.
- Rehab costs held in escrow may or may not be included in the fee base.
- Extension fees if the project runs past the loan term.
Ask each lender to confirm the fee base in writing. That one question separates a clean comparison from a misleading one.
Private Loan Monthly Payment Calculation: Interest-Only vs. Principal and Interest
Private loan monthly payment calculation comes down to which repayment structure you choose. Interest-only loans require you to pay just the monthly interest, with the full principal due at payoff.
Interest-only keeps payments low during a short hold, which suits fix-and-flip and bridge deals. Principal and interest builds equity but raises the monthly obligation. Neither is universally better; the right choice depends on your exit timeline.
The Monthly Payment Formula and Amortization
The interest-only payment formula is simple:
Monthly interest = loan amount × (annual interest rate ÷ 12)
For principal and interest, the standard amortization formula applies:
Monthly payment = P × [r(1 + r)^n] ÷ [(1 + r)^n − 1]
Where P is the principal, r is the monthly rate (annual rate ÷ 12), and n is the number of payments. Amortization spreads principal repayment across the term, so early payments are mostly interest and later payments are mostly principal.
Private Money Loan Cost Example: A Worked Real Estate Scenario
Picture an investor buying a distressed rental property. The purchase price is $250,000, and the lender funds $200,000 at 12% interest over a 12-month term with 2 points and $4,000 in third-party closing costs.
Scenario A: Interest-Only, 12-Month Term
| Cost Item | Calculation | Amount |
|---|---|---|
| Loan amount (principal) | Funded balance | $200,000 |
| Points | 2% of $200,000 | $4,000 |
| Third-party closing costs | Itemized | $4,000 |
| Monthly interest-only payment | $200,000 × (12% ÷ 12) | $2,000 |
| Total interest over 12 months | $2,000 × 12 | $24,000 |
| Total loan cost | Points + closing + interest | $32,000 |
| Balloon due at maturity | Full principal | $200,000 |
The all-in borrowing cost is $32,000 on a $200,000 loan, before any extension fees. That is the number to weigh against your projected equity and after-repair value (ARV), not the interest rate alone. Note the balloon: at month 12 the full $200,000 is due, so the exit, sale or refinance, must be ready.
Scenario B: Principal and Interest, 12-Month Term
Using the amortization formula with P = $200,000, r = 0.01 (12% ÷ 12), and n = 12:
Monthly payment = $200,000 × [0.01(1.01)^12] ÷ [(1.01)^12 − 1] ≈ $17,769
| Cost Item | Calculation | Amount |
|---|---|---|
| Monthly principal and interest payment | Amortization formula | ≈ $17,769 |
| Total payments over 12 months | $17,769 × 12 | ≈ $213,228 |
| Total interest | Total payments − principal | ≈ $13,228 |
| Points + closing costs | As above | $8,000 |
| Total loan cost | Fees + interest | ≈ $21,228 |
Principal and interest cuts total interest roughly in half versus interest-only, but it requires about $17,769 per month instead of $2,000. For a fix-and-flip with no rental income during the hold, that cash-flow burden is usually unworkable; for a stabilized rental with income, it can be the cheaper path.
Scenario C: Interest-Only With a 3-Month Extension
Suppose the sale slips three months. The lender charges a 2-point extension fee on the outstanding balance plus continued interest:
| Cost Item | Calculation | Amount |
|---|---|---|
| Extension fee | 2% of $200,000 | $4,000 |
| Additional interest | $2,000 × 3 months | $6,000 |
| Revised total loan cost | $32,000 + $4,000 + $6,000 | $42,000 |
A three-month delay raises the all-in cost from $32,000 to $42,000, a 31% increase, before counting carrying costs like taxes, insurance, and utilities. That is why the extension clause belongs in the original comparison, not the fine print.
Reading the Three Scenarios Together
- Interest-only minimizes monthly cash outlay but maximizes total interest and leaves a balloon at maturity.
- Principal and interest lowers total interest but demands a much larger monthly payment.
- Extensions are the hidden cost that turns a good deal into a marginal one; model the delay before you sign.
Calculator Limitations to Verify in the Loan Documents
Any calculator, including a spreadsheet you build yourself, makes assumptions that the loan documents may override:
- Interest on commitment vs. funded balance: some lenders charge interest on the full committed amount, including undrawn rehab funds. That raises the effective rate on money you actually use.
- Rehab draws: if interest is charged on drawn balances only, your interest cost falls as draws are spaced out; if on the full commitment, draw timing does not help.
- Prepaid interest: most private loans fund mid-month and charge per-diem interest to the first of the following month, which adds a small but real closing cost.
- Prepayment terms: a minimum interest period or prepayment penalty can make an early payoff more expensive than the calculator shows.
- Balloon and payoff costs: confirm the payoff date, any exit fee, and whether a refinance triggers a prepayment charge.
Run the numbers, then verify each assumption against the term sheet and loan agreement. The calculator tells you what a deal should cost; the documents tell you what it will cost.
How to Compare Offers and Calculate the True All-In Borrowing Cost
Comparing offers means comparing total loan cost, not headline rates. Build a simple scorecard for each lender:
- Total points and origination fees in dollars
- Third-party closing costs
- Interest rate and whether it is fixed
- Term length and extension terms
- Repayment structure (interest-only vs. principal and interest)
- Balloon payment date and payoff requirements
- Prepayment penalties
Then run a sensitivity check. If the project runs three months late, what does the extension cost you? Add that to the total. A lender with a slightly higher rate but no extension penalty may be cheaper in the end.
That scorecard is also your best defense against a bad deal. If a lender will not itemize fees in writing, that tells you something. For general guidance on borrowing costs and disclosures, the Consumer Financial Protection Bureau's resources on loan costs are a useful reference.
Frequently Asked Questions
How much do private money lenders charge in points and fees?
Private money lenders typically charge points ranging from 2 to 5 percent of the loan amount, plus an origination fee that may be separate or included. Closing costs such as appraisal, title, and legal fees also apply. Because pricing varies by lender and deal, request a itemized fee sheet from each lender. For a precise estimate on your property, consult Bailout Capital directly for current rates and terms.
What is the formula for a private loan monthly payment?
For an interest-only private money loan, the monthly payment equals the loan amount multiplied by the annual interest rate divided by 12. For a principal-and-interest loan, use the amortization formula: M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1 ], where P is principal, i is the monthly interest rate, and n is the number of payments. A private money loan calculator handles this math instantly.
How do loan points affect the total cost of a private money loan?
Points are upfront fees paid at closing, with each point equal to 1 percent of the loan amount. They increase the cash required at closing and raise the effective borrowing cost. For example, 3 points on a $200,000 loan add $6,000 to closing costs. When comparing offers, convert points into an annualized percentage to see the true all-in cost alongside the interest rate.
How can I compare two private money loan offers?
Compare the annual interest rate, points, origination fee, closing costs, and loan term side by side. Calculate the total interest paid over the expected repayment period, add all fees, and divide by the loan amount to get a rough all-in cost percentage. Also consider balloon payment structures and extension fees. A private money loan calculator can model each offer quickly, but always request a written term sheet from each lender.
