HELOC Payment Examples With Draw and Repayment
Review three HELOC examples showing interest-only draw payments, a new advance, draw-period principal, repayment payments, utilization, and interest.
How should you use these HELOC Calculator examples?
These examples turn the HELOC Calculator inputs into complete scenarios with stated values, calculation steps, and interpreted results. Use them to check how the calculator behaves, compare your own situation with realistic cases, and identify which inputs have the greatest effect before relying on an estimate.
Three HELOC Payment Examples
These examples are generated by the tested HELOC Payment Calculator. They isolate how a new advance and recurring draw-period principal change utilization, payment, end-of-draw balance and cost.
Each scenario uses a $100,000 line, 8.50% annual rate, 10 draw years remaining, 20 repayment years, a $50 annual fee, $500,000 home value, $280,000 first mortgage and an 85% maximum CLTV assumption.
Example 1: $50,000 Interest-Only Draw Balance
The borrower has a $50,000 current balance, takes no new advance and enters no draw-period principal.
Line position
| Starting balance | $50,000.00 |
|---|---|
| Available credit | $50,000.00 |
| Utilization | 50.00% |
| End-of-draw balance | $50,000.00 |
Payment phases
| First draw payment | $358.34 |
|---|---|
| Repayment payment | $438.08 |
| Payment change | $79.74 |
| Total interest | $96,639.63 |
With no principal during draw, the balance remains $50,000.00. The payment rises when that balance begins 20-year amortization, even though the example holds the rate constant.
Example 2: Take an Additional $25,000 Advance
The borrower adds a $25,000 advance to the existing $50,000 balance. Other inputs remain unchanged.
| Starting balance | $75,000.00 |
|---|---|
| Available credit | $25,000.00 |
| Utilization | 75.00% |
| First draw payment | $535.42 |
| End-of-draw balance | $75,000.00 |
| Repayment payment | $655.04 |
| Payment change | $119.62 |
| Total interest | $144,956.87 |
The advance raises utilization from 50.00% to 75.00% and reduces available credit. Because no principal is paid during draw, the full $75,000.00 enters repayment.
Example 3: Pay $250 of Principal Each Draw Month
The borrower keeps the $50,000 starting balance but adds $250 of principal to every draw-period payment.
| Starting balance | $50,000.00 |
|---|---|
| First draw payment | $608.34 |
| End-of-draw balance | $20,000.00 |
| Repayment payment | $177.73 |
| Payment change | -$430.61 |
| Total interest | $51,513.46 |
| Total fees | $1,500.00 |
| Interest and fees | $53,013.46 |
The first draw payment is higher because it includes $250 of principal. After 120 months, the balance is $20,000.00, so the later repayment payment is lower. The negative payment-change figure reflects the higher voluntary draw payment, not a refund.
Compare the Three HELOC Scenarios
| Scenario | Utilization | First draw payment | End-of-draw balance | Repayment payment | Total interest |
|---|---|---|---|---|---|
| Interest-only $50,000 balance | 50.00% | $358.34 | $50,000.00 | $438.08 | $96,639.63 |
| Add $25,000 advance | 75.00% | $535.42 | $75,000.00 | $655.04 | $144,956.87 |
| Pay $250 principal during draw | 50.00% | $608.34 | $20,000.00 | $177.73 | $51,513.46 |
A low initial payment is not automatically the lowest-cost choice. New advances increase balance and interest, while draw-period principal requires more cash now but reduces later repayment exposure. Variable rates can change all three outcomes.
Reproduce the Results
- Open the HELOC Payment Calculator and select Reset.
- Keep the shared rate, phase lengths, fee and equity values shown above.
- For Example 1, use a $50,000 balance with no new draw or draw principal.
- For Example 2, enter a $25,000 additional draw.
- For Example 3, return the draw to zero and enter $250 monthly principal during draw.
- Select Calculate and review the payment cards, rate chart and annual schedule.
