What is a standard tip?

15-20% is standard in the US. 15% for adequate service, 18% for good, 20%+ for excellent. Other countries vary widely.

Do I tip before or after tax?

Traditionally on the pre-tax amount, but many people tip on the total. Either is acceptable—the difference is usually small.

How do I calculate 20% tip quickly?

Move the decimal one place left (10%), then double it. For $45: 10% = $4.50, doubled = $9.00 tip.
