Starting from zero credit is actually easier than recovering from bad credit. Here's the honest, month-by-month breakdown of what scores are achievable, when, and using what strategy — with no exaggeration.
Starting from zero credit means you have no credit accounts at all — no loans, no cards, no history. This is actually a better starting position than having bad credit, because you have no negatives to overcome, only positives to add.
The challenge: FICO requires at least one account that has been open for 6 months AND at least one account that has been reported to a bureau in the last 6 months before it can generate a score. Until then, you are "credit invisible" — no score at all. Getting past this initial barrier is the first milestone.
Open a secured credit card and/or credit builder loan. No score yet — FICO needs 6 months. Use Experian Boost immediately (free, instant). If you become an authorized user, a score may appear sooner since you inherit the account's age.
If you became an authorized user on an old account, you may already have a score by month 1–2. For self-built accounts, an initial score of 580–620 commonly appears around month 3 with consistent perfect payments and very low utilization.
By month 6, your account has the minimum age for a FICO score. With perfect payment history and utilization under 10%, most people reach 600–640 by this point. This unlocks many secured card upgrades and basic loan products.
12 months of perfect payment history is a significant milestone. Most people reach 630–670 range. Some secured card issuers (Discover, Capital One) upgrade to unsecured at this point, returning your deposit. Score continues climbing as account ages.
18 months of perfect history with both installment and revolving accounts pushes most people to the 650–700 range. Most mainstream lenders now start to see you as a viable borrower for auto loans and personal loans at reasonable rates.
Two years of flawless credit history across multiple account types can produce scores of 670–730+. At this point, you're qualifying for competitive interest rates, unsecured credit cards with rewards, and many mortgage products.

Authorized user on a family member's old account (instant history) + secured credit card (utilization management) + credit builder loan (installment history) + Experian Boost (free). This combination, executed perfectly for 12 months, produces the strongest and fastest score growth — often reaching 670–720 within 18 months from zero.
