HELOC vs. HELOAN: How to Calculate Total Cost Including Closing Fees and APR

The Right Question Is Not Which Rate Is Lower

The advertised rate on a home equity line of credit or a home equity loan tells you almost nothing about which product costs less. Total cost depends on three variables that lenders rarely present side by side: closing fees, the APR calculated over your actual draw or repayment horizon, and the payment structure during each product's distinct phases.

A HELOC carries a variable rate, a draw period typically running 5 to 10 years, and a repayment period of 10 to 20 years. A home equity loan (HELOAN) carries a fixed rate and begins full principal-and-interest repayment immediately. Both structures have legitimate use cases. The error is treating them as interchangeable and selecting on rate alone.

How Closing Costs Change the Real APR on Each Product

Closing costs on a HELOC typically range from 2% to 5% of the credit line. On a HELOAN, they run 2% to 6% of the loan amount. Both figures include lender origination fees, title search, appraisal, and recording fees. Some lenders waive origination fees but embed the cost in a higher margin over the prime rate or the SOFR benchmark. Neither approach is free.

Worked Example: $100,000 HELOC Over 5 Years

Assume a $100,000 HELOC with a 3% closing cost totaling $3,000, a draw period of 10 years, and a current variable rate of 8.75% (prime plus 0.25% as of mid-2026). The borrower draws the full $100,000 immediately and makes interest-only payments during the draw period.

• Monthly draw-period payment: $100,000 x (0.0875 / 12) = $729.17
• Total interest over 60 months (5 years): $729.17 x 60 = $43,750
• Closing costs: $3,000
• Total 5-year cost before repayment phase: $46,750

If rates rise 150 basis points to 10.25% at month 13 and hold there, the recalculated interest for months 13 through 60 (48 months): $100,000 x (0.1025 / 12) x 48 = $41,000. The first 12 months at 8.75% add $8,750. Total draw-period interest climbs to $49,750, plus the $3,000 closing cost, for a 5-year outlay of $52,750. That is $6,000 more than the base-rate scenario. Variable-rate exposure is not theoretical risk. It is a dollar figure you can model.

Worked Example: $100,000 HELOAN Over 5 Years

Assume a $100,000 HELOAN at a fixed rate of 9.25%, a 4% origination and closing cost totaling $4,000, and a 10-year repayment term. The borrower pays off the loan in 60 months.

Monthly payment on a 10-year term: using the standard amortization formula, P x [r(1+r)^n] / [(1+r)^n - 1], where P = $100,000, r = 0.0925/12 = 0.007708, n = 120:

Monthly payment = $100,000 x [0.007708 x (1.007708)^120] / [(1.007708)^120 - 1] = $1,272.49

Total paid over 60 months (half the 10-year term, then payoff): this requires separating the amortization. After 60 payments, the remaining balance on a 10-year amortization at 9.25% is approximately $57,612. Total payments over 60 months: $1,272.49 x 60 = $76,349. Interest paid in those 60 months: $76,349 minus ($100,000 - $57,612) = $76,349 - $42,388 = $33,961.

Add the $4,000 closing cost: 5-year total outlay in interest and fees = $37,961. The borrower still owes $57,612 at payoff, but the cost-of-borrowing comparison over 5 years shows the HELOAN at $37,961 versus the base-rate HELOC at $46,750. The HELOAN costs $8,789 less on a 5-year horizon if rates hold.

Reverse that conclusion if rates fall. At 7.25% for the full 60 months, the HELOC's draw-period interest drops to $100,000 x (0.0725/12) x 60 = $36,250, plus $3,000 closing costs, for $39,250. The HELOAN still costs $37,961. The spread narrows to $1,289. The rate environment determines which product wins.

The APR Calculation You Need to Run

The Annual Percentage Rate on a HELOC includes the current margin, the index rate, and any periodic or lifetime caps. It does not reflect future rate changes. The APR on a HELOAN reflects the fixed rate plus all financed fees, expressed as a yearly cost. Neither number tells you the total cost over your specific use period.

To compare products correctly, calculate the following for each option:

1. Total closing costs paid at origination.
2. Total interest paid over your intended draw or use period (not the full loan term).
3. Remaining principal balance at the end of that period.
4. Sum of items 1 and 2. This is your borrowing cost for that horizon.

This approach eliminates the distortion created by comparing a 10-year HELOC draw period against a 10-year HELOAN term when your actual need is 5 years of access to capital.

Annual Fees and Inactivity Fees Compound the HELOC's True Cost

Many HELOC lenders charge annual maintenance fees of $50 to $100 per year. Some charge inactivity fees of $50 to $75 per year if the drawn balance falls below a threshold. On a 10-year draw period, annual fees add $500 to $1,000 to the base cost. A borrower who draws intermittently, uses $30,000 in year one and repays it, then draws $50,000 in year four, pays interest only on outstanding balances. But the fees accrue regardless of balance.

Factor these fees into the total cost calculation before comparing to a HELOAN, which typically carries no annual fee after closing.

Which Product Fits Which Use Case

A HELOC fits borrowers with staged capital needs: a renovation phased over 24 months, a business with irregular draw requirements, or a bridge financing need where the exit is predictable. The variable rate is manageable when the draw period is short and the borrower has rate-cap protection.

A HELOAN fits borrowers who need a single lump sum for a defined purpose: debt consolidation, a one-time improvement, or a purchase where the amount is fixed. The fixed payment simplifies cash flow planning. The higher closing costs are justified when the use period exceeds 7 to 10 years, spreading those fees across more months of borrowing.

Neither product is categorically superior. The math determines the answer for your specific amount, timeline, and rate environment.

Run the Full Comparison Before Choosing

The CalcMoney HELOC calculator computes total cost over any draw period you specify. Enter your credit line or loan amount, the offered rate, closing costs as a dollar figure or percentage, and your expected use period. The calculator outputs total interest, total fees, and a side-by-side cost comparison against a fixed HELOAN using current market rate data.

Use it with the actual term sheets from two or three lenders. Lenders issue these before a hard credit pull in most cases. Plug each set of numbers in and let the output rank them by total cost over your horizon, not by the rate printed at the top of the sheet.
