Here is the number nobody wants to say out loud: a FICO score cannot even exist until you have at least six months of reported activity. So if you are starting from a truly blank file, "how long to build credit from nothing to 700" has a floor built into the math, and it is not measured in weeks.
The good news is that 700 is very reachable. For most people building from scratch, 12 to 18 months of steady, boring, on-time behavior does it. The trap is not that it is hard. The trap is that it is slow, and slow is where people give up or fall for shortcuts.
This is a sequencing plan, not a promise. Your results depend on your own accounts and payment history. But the order below is how a thin file turns into a solid one.
Months 0-2: Open the first line and pull your reports
You need something reporting to the bureaus. The two most reliable starting points for a new file are a secured credit card (you put down a deposit that becomes your limit) and a credit-builder loan (you make fixed payments into a locked account and get the money at the end). Both report monthly. A credit-builder loan is designed for exactly this situation, and it is worth understanding how a credit-builder loan works before you pick one.
At the same time, pull your credit reports so you know your baseline. You are entitled to free reports, and here is how to get your free credit report from all three bureaus. A new file might show nothing yet, which is normal. What you are checking for is errors and any account you did not open.

Months 2-6: Let it report, and pay it perfectly
This is the quiet stretch. Your only job is to use the account lightly and pay on time every single month.
Charge one small recurring bill to your secured card, a streaming subscription or a phone bill, then set the card to autopay the full statement balance. That single move does two things: it generates on-time payment history, the biggest factor in your score, and it keeps your credit utilization low without you thinking about it.
You do not need to carry a balance. Paying in full still reports the account as active and on-time. Carrying a balance just donates interest to the bank.
Around month six, a score should appear. Do not panic if it is in the 640-680 range at first. A young file with a short history scores lower simply because there is not much history to judge, not because you did anything wrong.
Months 6-9: Add a second account, carefully
One account can carry you a long way, but a thin file with a single line stalls eventually. Adding a second account around month six or seven gives the score more to work with.
Good options: convert or add a second card, or if you started with a secured card, add a small credit-builder loan (or vice versa). A mix of a revolving account and an installment account tends to help.
One rule matters here: space out applications. Each application can trigger a hard inquiry, and clustering several in a month reads as risk on a new file. One new account, then let it settle for a few months.
If you have never separated the two ideas, our explainer on credit report vs. credit score is worth five minutes, because you are about to watch both move.
Months 9-14: Optimize utilization and keep the streak alive
By now you have a year of history forming. This is where you fine-tune.
Keep your reported utilization under 10% if you can. Utilization is calculated from the balance on your statement date, not what you owe after paying. So if you want a lower number to report, pay most of the balance down before the statement closes, not after the due date.
Keep every payment on time. A single 30-day late payment on a young file is genuinely costly and can undo months of progress, because payment history carries the most weight. Autopay is your friend.

Months 14-18: Push into the 700s and protect it
Fourteen to eighteen months in, a clean file with two or three seasoned accounts, on-time payments, and low utilization is typically knocking on 700 or already past it.
Do not sabotage the finish. Avoid opening new accounts right before you need your score for an apartment or a car, since each application dips it briefly and lowers your average account age. Keep old accounts open, because length of history keeps growing in your favor for free.
When something on your report is wrong
Building on top of an error wastes months. If a report shows an account that is not yours, a wrong balance, or a payment marked late that you made on time, you have the right to dispute it. Under FCRA § 611, the bureau must reinvestigate, generally within 30 days, and the furnisher has its own duty to investigate under § 623. Here is what the 30-day investigation timeline actually looks like, and a broader walkthrough of your FCRA rights in the dispute process.

The one thing that never speeds up
Every method above shares a bottleneck: accounts report roughly once a month. There is no version of this where 700 arrives in three weeks, and anyone selling that is selling a story.
But the flip side is genuinely encouraging. You do not need to be clever. You need one or two accounts, on-time payments, low balances, and patience measured in months. Start this month, and a year and a half from now your score will look nothing like your blank file did.
