Your credit score sets your mortgage rate, your rental applications and your insurance premiums. Work through the five steps in order, or go straight to the one you need. Your answers carry from one step to the next, so you are not asked the same thing twice.
1. Understand
What moves a credit score, and what only looks like it does.
| Factor | Weight |
|---|---|
| Payment historyThe biggest single factor. Pay every bill on time, every month. What one 30-day late costs depends heavily on what your file already looks like — roughly 90–110 points on a clean, high-scoring file, but only about 15–35 on one that already carries delinquencies. | 35% |
| Credit utilizationBalances as a share of your limits. Under 30% is the floor, under 10% is where it stops holding you back. Unlike the rest of this list it is not historical — it unwinds as soon as a lower balance is reported, which makes it the fastest lever you control. | 30% |
| Length of credit historyThe age of your oldest account, your newest, and the average of all of them. Do not close old cards — you keep the limit and the age by leaving them open, and closing one can raise your utilization overnight. | 15% |
| New creditEach hard inquiry costs roughly 2–10 points and fades within about a year; opening the account itself costs another 5–20 or so by pulling down your average age. Rate shopping for a mortgage or auto loan inside a 14–45 day window counts as one inquiry. | 10% |
| Credit mixHaving both revolving credit (cards) and installment loans (auto, personal, student) helps a little. It is the smallest factor on this list — never take on debt you do not need just to improve your mix. | 10% |
How utilization actually works
Utilization is your reported card balances divided by your reported limits. It is measured both per card and across all your cards, and a single maxed card can hurt even when your overall number looks fine.
The figure that counts is whatever the issuer reports, which is usually your statement balance — not what you owe after you pay. That is why paying in full every month can still leave you looking heavily utilized: pay before the statement closes, not just before the due date.
It carries no memory. Nothing about last year's balances is held against you, so a paydown shows up on the next reporting cycle. That is what makes it the fastest legitimate move available to most people.
Disputing an error — and when not to
You can dispute anything inaccurate or unverifiable yourself, free, under the Fair Credit Reporting Act. Bureaus have 30 days to investigate (45 if you send new evidence), and anything they cannot verify has to come off. No company can do more than this for you, whatever they charge.
File with every bureau that reports the item — they investigate separately, so an error fixed at one can sit untouched at another. Attach proof, and diary a follow-up for day 31.
Timing matters if you are buying a home. While a dispute is open the tradeline is flagged as disputed, and both Fannie Mae Desktop Underwriter and Freddie Mac Loan Product Advisor issue messages on disputed accounts — which can force re-verification or manual underwriting and delay a closing. Dispute early, and have everything resolved before you apply.
Before you pay a collection
Check the statute of limitations in your state first. In many states a partial payment, or even a written promise to pay, revives a time-barred debt and restarts the clock — turning a debt nobody could sue you over into one they can. This is the only irreversible step in dealing with collections.
Then ask whether it needs paying at all. Fannie Mae and Freddie Mac generally do not require non-mortgage collections to be paid off on a one-unit primary residence, though thresholds apply for second homes, investment properties and FHA loans. Paying can drain a down payment without changing whether you qualify.
Expect pay-for-delete to be refused. Most large collectors decline it as a matter of policy. Treat a deletion as a bonus, never as the plan — and get any agreement in writing, signed, before any money moves.
2. Assess
Answer ten questions once. Every tool below reads your answers from here.
Ten multiple-choice questions about where your credit stands: score range, utilization, late payments, collections, and how thick your file is. It asks for no account numbers or Social Security number and does not touch your credit report. Your answers are saved on this device and feed every tool on this page.
3. Simulate
Model a change before you make it. The result is a range, because no score model is exact.

4. Plan
A week-by-week sequence built from your answers, weakest area first.
Need more than a quick fix? Follow a week-by-week plan to a mortgage-ready score.
The Credit Roadmap turns ten answers into a 8 to 36 week program: disputes, utilization, collections and new accounts, tracked weekly. Free, without an account.
5. Buying a home
The extra layer that applies only if a mortgage is the goal.
Mortgage underwriting judges credit differently from the score you see for free: it pulls older FICO models, weighs a paid collection much like an unpaid one, and reacts badly to a tradeline still flagged as disputed. Score your readiness across credit, debt ratio, down payment and reserves together, the way an underwriter does.
Building US credit from zero
For immigrants and visa holders with a thin or empty file.
A thin or empty credit file is one of the most common problems for new immigrants. Without US credit history you pay higher deposits, get turned down for rentals and miss the best loan rates. With the right sequence you can build a strong file in 12 to 18 months.
- 1Open a secured credit card with a $500 to $1,000 deposit.Use it for one recurring charge and pay it in full each month.
- 2Become an authorized user on a family member's US account.The account needs a good payment history for this to help.
- 3Use an ITIN if you do not have a Social Security number yet.ITIN holders can open accounts and start building a file before an SSN arrives.
- 4After 12 months, apply for an unsecured card.At 24 months, a small car loan or a Roth IRA adds account mix.
