Chapter 16 / Credit Score

Does a Balance Transfer Hurt Your Credit Score?Briefly yes, then no, plus the one mistake that actually hurts.

A balance transfer has three score effects in sequence. A short-term dip from the hard pull. A medium-term lift from lower utilisation. A long-term effect that depends entirely on whether you keep the old card open. The order matters.

The three phases

Score timeline.

No.01 / Day 1 to Day 30

Hard pull

-3 to -5 pts

The application triggers a hard inquiry on your credit report. New credit accounts for 10% of FICO. The drop is temporary and fades within 6 months.

No.02 / Day 30 to Day 90

Utilisation lift

+10 to +30 pts

The new card's credit limit registers at the bureaus. Total available credit goes up. Your utilisation ratio drops, which is the second-largest FICO factor (30%).

No.03 / Month 4 to Month 18

Payoff progress

+20 to +60 pts

As you pay down the transferred balance, utilisation drops further. By month 18 of a 21-month BT successfully repaid, total score lift is typically 30 to 80 points net.

The mistake that actually hurts

Closing the old card.

Once the transfer clears, the old card has a $0 balance. Many people close it, assuming it serves no further purpose. That is the single biggest mistake in balance-transfer execution. Closing the old card removes its credit limit from your total available credit, which spikes utilisation right back up.

Keep open: utilisation lift preserved

Old card: $5,000 limit, $0 balance.
New card: $10,000 limit, $8,000 balance.
Total: $15,000 limit, $8,000 balance.
Utilisation: 53%.

Closed: utilisation re-spikes

Old card: closed.
New card: $10,000 limit, $8,000 balance.
Total: $10,000 limit, $8,000 balance.
Utilisation: 80%. Score loss: 30 to 60 points.

The fix is simple. Keep the old card open. Set up a single small recurring charge on it (a streaming subscription is the standard play). Pay it off in full each month. The card stays active, the limit stays in your total, the utilisation lift stays intact.

Worked example

Sarah, 680 FICO, $12K balance.

Sarah has $12,000 across two cards with combined $15,000 limits. Utilisation 80%. FICO 680. She applies for a 21-month BT card, gets approved with a $10,000 limit. Score path:

Day 0: starting score680
Day 1: hard pull (-4 pts)676
Day 30: new $10K limit registers, util drops to 48%695 (+19)
Month 6: paid down $4,000, util at 32%712 (+17)
Month 12: paid down $7,500, util at 18%728 (+16)
Month 18: paid down $11,500, util at 2%745 (+17)
Net change over 18 months+65 pts
Frequently asked

About credit score and BTs.

Does a balance transfer hurt your credit score?+
Briefly yes, then no. The hard pull from the application drops your score by 3 to 5 points for a few months. Within 30 to 60 days the new card's credit limit registers and your utilisation ratio drops, which typically lifts your score 10 to 30 points net. The mistake that actually hurts is closing the old card afterwards.
How much does the hard pull cost in points?+
Typically 3 to 5 points for a single hard inquiry. Multiple hard pulls inside 90 days compound: two pulls is 6 to 10 points, three is 10 to 15. New credit accounts for 10% of FICO. The drop fades within 6 months and the inquiry falls off the report entirely after 24 months.
Why does opening a new card raise my score?+
Credit utilisation, the ratio of total balances to total credit limits, accounts for 30% of FICO. Adding a new card with a $5,000 limit when you have $8,000 of balance on $10,000 of existing limits drops your utilisation from 80% to 53%. That alone typically lifts the score by 20 to 40 points within 60 days.
Should I close the old card after the transfer?+
No. Closing the old card removes its credit limit from your total available credit, which raises your utilisation back up. If your old card had a $5,000 limit and you close it, total available drops by $5,000, utilisation re-spikes, and the score gain from the new card vanishes. Keep the old card open. Use it for a small recurring charge to prevent inactivity closure.
