I do something similar, but my "formula" also takes a few other inputs, like the security level of the website and the number of times I've had to change the password for regular password changes. The hope is that I have a hard-to-brute-force password, and if one password is revealed, it won't be a key for all my other accounts, but I only have one thing to remember for dozens of accounts. I can't even tell you the number of times I've gone to a website, said to myself, "I know I have an account here...was it before or after I started using the password formula?" and applying the formula gets me into my account.
