Credit Score Guide 2026: What Moves It, How Fast, and What It Costs on a Mortgage
Short answer: on a $400,000 mortgage, the gap between a 760 score and a 640 score is roughly 1.0–1.3 points of rate — about $330 a month and $120,000 over 30 years. Utilization and payment history move a score fastest; most other advice is noise.
What a credit score is made of
FICO, the model most mortgage lenders use, weights five things: payment history (35%), amounts owed and utilization (30%), length of history (15%), new credit (10%) and credit mix (10%). Mortgage lenders pull all three bureaus and use the middle score of the lowest-scoring borrower. The score bands lenders actually price on are: 760+ (best), 740–759, 720–739, 700–719, 680–699, 660–679, 640–659, 620–639, below 620 (conventional loans unavailable; FHA possible to 580, sometimes 500 with 10% down).
What a lower score costs in 2026
| Score band | Typical rate add-on vs 760+ | $400,000 payment | Extra interest, 30 yrs |
|---|---|---|---|
| 760+ | — | $2,715 (7.2%) | — |
| 720–739 | +0.25 | $2,784 | $25,000 |
| 680–699 | +0.5 to 0.75 | $2,853–$2,922 | $50,000–$75,000 |
| 640–659 | +1.0 to 1.25 | $2,992–$3,047 | $100,000–$120,000 |
| 620–639 | +1.5 or more; PMI much higher | $3,117+ | $145,000+ |
Add-ons are illustrative of conventional pricing adjustments; actual pricing depends on loan-to-value and lender. On personal loans the spread is far wider: a 760 score might see 9%–12% APR, a 640 score 20%–30%.
The fastest legitimate ways to raise a score
- Cut utilization before the statement date. Utilization is reported as of each card's statement closing date, not the due date. Paying a $4,000 balance on a $5,000 card down to $400 before the statement closes drops utilization from 80% to 8% and can move a score 20–50 points within one cycle. Under 30% is the usual advice; under 10% is where the best scores live.
- Ask for a credit-limit increase. Same balance, higher limit, lower utilization. Many issuers do this with a soft pull; ask before you accept.
- Dispute errors. Roughly one in five reports has an error. Under the Fair Credit Reporting Act the bureau must investigate within 30 days. Dispute online at Equifax, Experian and TransUnion separately, attach documents, and keep the confirmation. Common errors: accounts that aren't yours, paid collections still showing as open, wrong late-payment dates.
- Bring every account current. A single 30-day late can cost 60–100 points on a high score; the damage fades over two years but stops only when payments are current.
- Become an authorized user on a family member's old, low-utilization card. The account's history is added to your file at most issuers.
- Do not close old cards. Closing reduces available credit (raising utilization) and, eventually, average account age.
Soft pull vs hard pull
A soft inquiry — checking your own score, pre-qualification, employer or insurance checks — never affects your score. A hard inquiry happens when you apply for credit; it costs up to about 5 points and stays on the report for two years, counting for one. FICO treats all mortgage (and separately all auto) inquiries within a 45-day window as one inquiry, so shopping five lenders in two weeks costs the same as shopping one. Personal loan pre-qualification is a soft pull at nearly every online lender; the hard pull comes only when you accept an offer.
Myths that cost people money
- "Carrying a balance builds credit." No. Paying in full every month builds credit; the balance that matters is the one on the statement, and lower is better.
- "Checking my score lowers it." No — that is a soft pull.
- "Closing a card I don't use helps." Usually the opposite.
- "Paying off a collection removes it." Paid collections still show for seven years from the original delinquency, though newer FICO and VantageScore versions ignore paid collections, and medical collections under $500 are no longer reported.
- "Income affects my score." Income is not in the report at all; lenders check it separately for DTI.
Building credit from nothing
A secured card (deposit equals limit), a credit-builder loan from a credit union, and rent-reporting services that add on-time rent to Experian are the three standard routes. Use the card for one small recurring bill, pay it in full, and expect a usable score in six months and a 700+ score in 12–24 months if nothing goes wrong.

Timing a mortgage application
Scores move slowly except for utilization, so start 90 days before you apply: pay cards down before statement dates, dispute errors, make no new applications, and do not pay off old installment loans early (that can remove a positive account). Once pre-approved, change nothing until closing. If you are between 620 and 700 and not in a hurry, three months of work can be worth 0.5 points of rate — on $400,000, about $130 a month for 30 years.
