A credit score is one of the most important numerical indicators of your financial health. Whether you’re applying for a mortgage, a car loan, or even a rental apartment, your credit score plays a major role in how lenders and landlords assess your reliability. The Credit Karma Score Calculator offers a simple yet powerful way to estimate your credit score based on key variables like payment history, credit utilization, age of accounts, and more.

Credit Score Estimation Formula (Simplified)
While Credit Karma’s scoring model is based on VantageScore (not FICO), the overall categories and weightings are fairly consistent. The calculator uses the following estimated weighting:
- Payment History – 40%
- Credit Utilization – 20%
- Credit Age – 15%
- Total Accounts – 10%
- Hard Inquiries – 10%
- Derogatory Marks – 5%
Estimated Score = (PH * 0.4) + (CU * 0.2) + (CA * 0.15) + (TA * 0.1) + (HI * 0.1) + (DM * 0.05)
Each category is normalized to a scale of 0–100 before being weighted.
Example Calculation
Let’s take an example:
- Payment History: 98%
- Credit Utilization: 12%
- Credit Age: 5 years
- Total Accounts: 8
- Recent Inquiries: 1
- Derogatory Marks: 0
Score Calculation:
- PH score = 98
- CU score = 88 (lower utilization is better)
- CA score = 75 (higher is better)
- TA score = 70
- HI score = 90 (fewer inquiries is better)
- DM score = 100 (no derogatory marks)
Estimated Score = (98×0.4) + (88×0.2) + (75×0.15) + (70×0.1) + (90×0.1) + (100×0.05)
= 39.2 + 17.6 + 11.25 + 7 + 9 + 5
= 90.05 out of 100
Converted to a credit score: ~800
