Both a HELOC and a personal credit card are revolving credit — draw, repay, draw again. The difference is collateral and cost: a HELOC uses your home as collateral for a rate roughly a third of a card's, while a card puts nothing at risk but charges 20%+ on any balance you carry past the grace period. For large purchases you'll pay off slowly, a HELOC usually wins on cost. For small, short-term spending you can clear before the statement closes, a card's 0% grace period beats even the lowest HELOC rate.
Quick answer: Choose a HELOC if you have 20%+ home equity and need to carry a balance of $10,000+ for months at the lowest possible rate (7–11% variable); choose a personal credit card if you need funds in minutes, plan to pay the balance off within the grace period, or don't own a home — a HELOC secures the debt against your house and takes weeks to open, while a card is unsecured, instant, and charges 20%+ APR the moment a balance carries past the due date.

Pick HELOC (Home Equity Line of Credit) if: Homeowners with 20%+ equity who need to carry a larger balance for months and want the lowest possible carrying cost.
Pick Personal Credit Card if: Borrowers without home equity, or anyone spending an amount they can clear within one or two statement cycles.
For any balance you'll carry longer than one statement cycle, a HELOC is almost always cheaper — 7–11% variable APR versus 20–29% on a standard credit card. The gap widens with time: a $20,000 balance carried for a year costs roughly $1,400–$2,200 in interest on a HELOC versus $4,000–$5,800 on a card at standard APR. A card only wins on cost if you pay the full balance within the grace period, in which case it's effectively 0% either way.
A credit card wins decisively on speed. Most issuers approve within minutes and many allow instant digital-wallet spending before the physical card arrives, with the card itself shipping in about a week. A HELOC requires a home appraisal, title work, and a closing process similar to a mortgage refinance — typically 2–6 weeks from application to funded draw. For time-sensitive spending, a card is the only realistic option.
A HELOC does; a credit card does not. A HELOC is a second mortgage secured by your home — defaulting can lead to foreclosure, the same as a first mortgage. A credit card is unsecured debt: default damages your credit score and can lead to collections, but the issuer has no claim on your home. If risk tolerance matters more than rate, that difference alone can decide the choice.
For a short-term need you can pay off within the intro window (typically 12–21 months), a 0% intro APR card can beat a HELOC on cost since you pay no interest during the promotional period. The risk is what happens after the intro rate expires — the balance reverts to the standard 20–29% APR, and any remaining balance becomes expensive fast. For a need you can fully retire within the promo window, the card wins; for anything larger or open-ended, a HELOC's lower ongoing rate is the safer bet.
Most lenders require 15–20% equity remaining after the HELOC is drawn, meaning a combined loan-to-value (CLTV) of 80–85% or lower. Lenders calculate CLTV as (existing mortgage balance + HELOC limit) ÷ appraised home value. A renter or a homeowner with limited equity can't access a HELOC at all — a credit card (or personal loan) is the only revolving-credit option available regardless of rate preference.
