Short answer: Some improvements can show up within a month or two, such as correcting an error or getting a missed payment up to date so it stops repeating. Serious negative information takes much longer. Missed payments stay on your repayment history for two years, and defaults and credit enquiries stay for five years.
A realistic timeline
| Timeframe | What can change |
|---|---|
| Within about 30 days | Errors corrected after a correction request. Credit providers and reporting bodies generally have 30 days to deal with it |
| 1–3 months | New on-time payments start appearing in your monthly repayment history. Lower balances on cards may be reflected |
| 6–12 months | A steady run of on-time payments begins to outweigh older late payments |
| 2 years | Individual late payments (14+ days overdue) drop off your repayment history |
| 5 years | Defaults and credit enquiries are removed, whether the default was paid or not |
Credit scores are calculated by each credit reporting body using its own model, so the same change can move your score differently with each one.
Things that can help relatively quickly
- Check all three reports. You can get a free copy from Equifax, Experian and illion every three months. Errors such as a debt that isn't yours, a duplicated default or a wrong date are more common than people expect.
- Bring overdue accounts up to date. Each month you stay behind adds another late mark. Getting current stops the damage.
- Pay a default. It stays listed, but the status changes to paid, which many lenders treat quite differently.
- Reduce card limits you don't need. Lenders assess your total available credit, not just what you owe, so a lower limit can improve your borrowing position.
- Stop applying. Each application adds an enquiry. Several in a short period can look like credit stress.
What won't work
No one can legally remove accurate information from your credit report. Be wary of "credit repair" services charging large fees for things you can do yourself for free. Moneysmart explains how to get your reports and fix errors. Checking your own score doesn't hurt it.
Do you need to wait before applying?
Not always. Lenders look at more than a number: your income, expenses, bank statements and the story behind any marks. If your file has one old issue and your finances are otherwise solid, a licensed broker may be able to tell you whether waiting would actually make a difference. If there are recent missed payments, a few months of clean conduct often helps more than anything else.
