Business Debt Refinancing: Lower Payments, Longer Debt?

A replacement loan can look attractive beside today’s combined payment. The more useful comparison follows what the old payments would become as each debt ends. This fictional exercise separates first-year breathing room from the amount and duration of the remaining commitment.

PNC’s refinancing guide notes that combining debts can simplify payments, while extending a nearly repaid loan can increase cost. Check payoff and prepayment charges, new origination and collateral-related costs, and overlapping interest. Actual written terms govern; this illustration is not an offer.

Trace the $103,000 before calculating payments

All figures are invented. Start immediately after the last old payment. Loan A’s $40,000 balance and Loan B’s $60,000 balance equal their immediate payoff amounts. The replacement principal is $103,000: $100,000 goes directly to the old lenders and $3,000 finances a fee. Nothing reaches operating cash.

After both payoffs are completed, the model contains $103,000 of new debt, not $203,000 of combined old and new debt. The fee is already inside the replacement principal and its payments; do not add it again to the payment total.

• Old Loan A: $40,000, 12% nominal annual interest, 12 months remaining.
• Old Loan B: $60,000, 9% nominal annual interest, 36 months remaining.
• Replacement: $103,000, 8% nominal annual interest, 60 months.

Each rate is fixed in this exercise. Payments occur monthly at month-end, beginning one month later, using annual interest divided by 12. There is no unpaid interest at settlement, penalty, other fee, refund, tax effect, cash-out, balloon or other debt. These are contract interest rates, not disclosed APRs. Actual lender rounding and schedules can differ.

Compare three stretches of the calendar

The calculated monthly payments are $3,553.95 for A, $1,907.98 for B and $2,088.47 for the replacement. All comparisons below use unrounded calculations and round only the displayed answer; adding or subtracting displayed cents may differ by a penny.

1. Months 1–12: the old combined payment is $5,461.94, versus $2,088.47 new. Initial relief is about $3,373.47 a month.
2. Months 13–36: A has ended, leaving $1,907.98 a month on B. The replacement is now about $180.48 more a month.
3. Months 37–60: both old loans would be finished. The replacement still requires $2,088.47 a month for another 24 months.

The first difference cannot be multiplied by 60 and called savings. That would pretend Loan A survives its scheduled finish and Loan B continues beyond month 36. Put those two ending dates on the comparison before interpreting any payment reduction.

Check what remains owed at each milestone

Immediately after month 12’s payments, the old plan has $41,764.14 left, all on B. The replacement has $85,547.67 left. Lower first-year payments therefore leave a substantially larger balance in this scenario.

After month 36, the old plan’s balance is zero, while the replacement still owes $46,177.18. That amount is remaining principal, not a bill to add to all 60 replacement payments: those later payments already repay it.

Keeping the old loans produces $111,334.84 in remaining scheduled payments. The replacement produces $125,308.12, or $13,973.28 more. This compares all future scheduled outlay from the same starting point until both alternatives end. It is undiscounted nominal dollars, not present value, a tax analysis or an APR calculation.

The example assumes no return earned by deploying first-year relief. A business evaluating that possibility would need a separate supported operating plan. Costs irrevocably paid before this comparison are excluded; principal still outstanding remains part of the debt.

Give each replaced account an evidence card

Use a separate private card for A and B. These are questions for completing the model, not promises about a lender’s process:

• Dated payoff and validity date?
• Sender, receipt and confirmed application of funds?
• Zero balance and open/closed status?
• Collateral/guarantee release questions for lender or lawyer?
• Old debit instructions confirmed?

For the replacement, record principal, payoffs, financed fee, operating proceeds, first payment, rate/reset terms, maturity, collateral and personal promises.

Unconfirmed payoff means the one-loan assumption remains unresolved. Funding alone does not verify lien or guarantee release. A pending refinance does not extend payment deadlines; keep required payments current.
