Improving credit scores takes consistent time and effort, there is no way to instantly improve it. Here are some strategies that, when practiced consistently, will help you increase credit score over time and help maintain it:
Paying credit card dues, EMIs, and utility bills on time.
Keeping credit card utilization below 30% of the available limit on each card.
Avoiding multiple new applications for credit within a short period of time.
Keeping old credit accounts open to demonstrate a longer history of responsible credit management.
Regularly monitoring your credit report for any errors and promptly disputing them with the relevant credit bureau.
