Who calculates Credit scores?

The credit bureaus then compile the data from all the sources into a credit report for each individual which contains detailed information about one’s credit history and behavior.

What are the factors considered by calculating credit scores?

Credit scores are calculated based on various factors, each having its weightage in the scoring model. The following are the key factors that are considered while calculating credit scores:

  • Payment History (Weightage: 35%):

The most important component in evaluating your credit score is your payment history. It illustrates your history of on-time payments. Lenders prefer to see a history of consistent, on-time payments since it shows dependable money management.

Impact: Consistently making payments on time contributes positively to your score. On the flip side, late payments, defaults, or accounts sent to collections can severely damage your credit score. The more recent and frequent the late payments, the more detrimental their impact.

  1. Credit Utilization (Weightage: 30%)

Credit utilization measures the amount of credit you’re using compared to your available credit limit. It’s calculated for each credit account and as an overall percentage. 

Impact: High credit utilization, meaning you’re using a large portion of your available credit, can negatively affect your score. Aim to keep your credit card balances low relative to your credit limits.

  1. Length of Credit History (Weightage: 15%)

This factor considers the age of your credit accounts, including the age of your oldest and newest accounts, as well as the average age of all your accounts.

Impact: Generally, longer credit histories are seen as more favorable because they provide a more extended track record of financial responsibility. Opening and closing accounts frequently can shorten your average credit history.

  1. Types of Credit used (Weightage: 10%)

This factor assesses the diversity of your credit portfolio. Credit scoring models look at the mix of credit accounts you have, such as credit cards, installment loans (e.g., auto loans, mortgages), and retail accounts.

Impact: Having a well-rounded mix of credit types can positively affect your score. It suggests that you can handle various financial responsibilities. However, don’t open unnecessary accounts solely to diversify, as it may lead to inquiries and temporary score dips.

  1. New Credit Inquiries (Weightage: 10%)

New credit inquiries reflect how often you’ve applied for credit recently. It encompasses both hard inquiries (initiated by lenders when you apply for credit) and soft inquiries (e.g., checking your own credit or pre-approval checks).

Impact: Frequent hard inquiries within a short period can indicate financial instability and may temporarily lower your credit score. Soft inquiries, like checking your credit report, have no impact on your score. 

  1. Public Records and Collections

It includes public records such as bankruptcies, tax liens, and accounts sent to collections, all of which signify financial difficulties or unpaid debts.

Impact: Public records and collection accounts have a substantial negative impact on your credit score and can stay on your credit report for several years, making it challenging to secure new credit or loans.

How you can improve your credit score?

  1. Avoid Late Payments

Avoiding late loans or credit card payments is crucial for maintaining a positive credit score. To prevent late payments, you can employ strategies like setting up reminders, automating payments, and organizing monthly task schedules.

  1. Regularly Monitor Your Credit Report

Frequently checking your credit report is essential for detecting any errors or fraudulent activities that may negatively impact your credit score. Thoroughly review your credit report and dispute any inaccuracies or inconsistencies you find.

  1. Keep Your Credit Utilization Low

Credit utilization refers to the proportion of credit you use compared to your credit limit. Experts recommend maintaining a credit utilization rate below 30% to ensure a healthy credit score. Achieve this by paying off your balances in full each month or requesting a credit limit increase.

  1. Steer Clear of Frequent Credit Inquiries

Avoid making multiple credit applications simultaneously, as this signals to lenders that you have a high demand for credit. Each time you submit a loan application, it results in a credit inquiry, and frequent applications can negatively affect your creditworthiness. Therefore, only apply for new credit when it’s genuinely important.

  1. Refrain from Closing Credit Accounts

Closing old accounts or credit cards is generally not favorable. Old accounts demonstrate your long-standing relationship with the bank and your extensive repayment history. Closing them erases this positive history and can have an adverse impact on your credit score.

  1. Monitor Co-Signed Loans

Being vigilant is crucial when you’ve co-signed a loan. Sometimes, unexpected financial emergencies can lead the borrower to miss payments, affecting only your credit score. Therefore, it’s advisable to keep a close eye on any loans for which you’ve co-signed.
