3 months ago, my credit score took a massive dip. The consensus was that this happened because I no longer had any credit cards and thus no revolving debt.

So I went out and got myself a new credit and I made sure that it reported to the credit agencies. This was the result:

enter image description here

Obviously the biggest change is the Experian score. In January, when I didn't have any revolving debt, the Experian score dropped by 30 points. Today, it went up by over a 100. I dutifully compared the January and March credit reports and other than this new credit card, everything is absolutely the same.

The Equifax score is also a bit baffling. It also dropped in January, but went up double the drop in March. Transunion is the most consistent of all - the peaks and valleys are easy to understand.

So, can someone tell me why all these perturbations are happening? Everything I read states that the scores should be predictable.

    Your credit score is quite good, so don't worry about the changes. Since you say you "no longer had credit cards and thus no revolving debt", I suspect that you were carrying a balance for a while and had managed to pay it off, perhaps under guidance from a debt counselor (who often as a first step insist on NO CREDIT CARDS). If so, and you have gone out and acquired a new credit card now that you are debt-free, don't fall back into your old habits, pay off your credit card IN FULL (not just the minimum required payment) every month, and your credit score will improve even more.

    How did you generated the chart? What's the service called?

Scoring is based on:

  • Length of oldest credit account on file
  • Debt / Credit Line Ratio
  • Payment History

What you're seeing here is how the various credit agencies weight the debt/credit ratio and current payment history. Also note that your situation is somewhat exceptional, which explains the rapid shift.
