Credit points

No, it depends on your particular situation of credit history, total credit limit, total usage, and whether you have late payments on your history.  The shorter your history and lower your overall limits, the fewer points it will go up.  It also depends on where you're starting from - if you're at 600, you'll get bigger jumps; if you're at 800, you'll get smaller changes.

I believe late payments stay on there for 7 years, so that's how long it takes to be completely free from their effects, but they have less effect after a year or two, but the clock starts all over if you miss a payment again.
