Most personal debt consolidation loans run 24 to 84 months, with 36 to 60 months being the most common. HELOCs and cash-out mortgage refinances run 10 to 30 years. Longer terms lower the monthly payment but raise the total interest paid; shorter terms raise the monthly payment but cut total interest substantially. The right term is usually the shortest one that produces a payment you can sustain.

Personal loan term ranges by lender.

SoFi: 24 to 84 months.

Marcus: 36 to 72 months.

Discover: 36 to 84 months.

LightStream: 24 to 144 months (longer terms available for higher-amount loans).

Best Egg: 36 to 60 months.

Credit unions: 12 to 84 months, varies by institution.

Upstart: 36 to 60 months.

OneMain: 24 to 60 months.

The math of term length. A $20,000 loan at 9% APR shows the term trade-off:

24 months: $914/month, total interest $1,930, total cost $21,930.

36 months: $636/month, total interest $2,890, total cost $22,890.

48 months: $498/month, total interest $3,890, total cost $23,890.

60 months: $415/month, total interest $4,920, total cost $24,920.

72 months: $361/month, total interest $5,990, total cost $25,990.

84 months: $322/month, total interest $7,090, total cost $27,090.

Going from 36 months to 84 months drops the monthly payment by half ($636 to $322) but costs an extra $4,200 in total interest. The longer term isn't "cheaper"; it's more affordable per month at the cost of more total dollars over time.

How to pick the right term.

Start with the shortest term you can sustain. Calculate your monthly cash flow after fixed expenses (rent, utilities, food, insurance, transportation, minimum savings). The remaining surplus is what's available for debt payments. Pick the term whose monthly payment fits comfortably within that surplus, with $200-$400 of cushion for emergencies.

Match the term to the existing payoff timeline. If your existing card balances would be paid off in 36 months at current minimums plus extra payments, don't take a 60-month consolidation loan unless the rate spread is dramatic. The longer term often eats the rate savings.

Don't extend beyond 60 months without a clear reason. 72- and 84-month loans look attractive because the monthly payment is low, but the total interest cost can substantially exceed the credit card debt you're paying off. Run the math both ways.

Don't go shorter than your budget can sustain. A 24-month loan you can't afford produces missed payments, late fees, and credit damage. Better to take a 48-month loan you can pay easily than a 24-month loan you can't.

The interest-rate-times-time math. Total interest paid is roughly proportional to rate × time × balance. Doubling the term roughly doubles the total interest at the same rate. Cutting the rate in half roughly halves the total interest at the same term. Both matter, but term length is often the variable that gets shopped less carefully than rate.

How term affects rate. Some lenders quote slightly higher rates for longer terms because the lender takes on more risk over a longer window. The difference is typically 0.5 to 1.5 percentage points between 36-month and 84-month terms with the same lender, same borrower. Combined with the term-length math, the longer-term loan can cost meaningfully more.

Prepayment without penalty. Most modern personal consolidation loans have no prepayment penalty. You can take a 60-month loan and pay it off in 36 months by making extra principal payments. The total interest will be less than the 60-month full schedule. This gives you flexibility: lock in the lower monthly payment in case income drops, but pay aggressively when income is strong.

HELOC and cash-out mortgage terms.

HELOC: typically 10-year draw period (you can borrow and repay during this window) followed by 10- to 20-year repayment period. During draw, you may have interest-only payments; during repayment, principal-and-interest. The draw-then-repayment structure can produce a payment shock when repayment begins.

Cash-out mortgage refinance: typically 15- or 30-year fixed mortgage. The cash-out portion is amortized over the same term as the rest of the mortgage. Stretching credit card debt over 30 years at 6.5% can produce more total interest than the original credit cards even though the rate is lower.

The credit card timeline benchmark. Average credit card debt at 22% APR with $400/month payments: payoff takes about 80 months and costs about $11,800 in interest on a $20,000 starting balance. Almost any consolidation option that ends within 60 months saves money. The benchmark to beat is your existing card payoff timeline, not zero.

Picking the term in practice. Calculate three numbers: monthly payment at 36-month, 48-month, and 60-month terms. Pick the shortest one whose payment is at most 80% of your sustainable surplus (leaving 20% buffer for life). If your sustainable surplus is $600, target a payment under $480. The 36-month term in the example above ($636) wouldn't fit; the 48-month ($498) would; the 60-month ($415) would too. The 48-month is closer to optimal.

Pick the shortest term you can sustainably afford. Set up auto-pay for that fixed amount. Make extra principal payments when you have surplus. The math is straightforward; the discipline is what determines whether you actually finish ahead of schedule.
