If a single person is making $50,000 per year, they were in the 25% tax bracket in 2013 (your source), which means you would get back $1250 on a $5000 donation (the deduction applies to the marginal rate, not the average). If you expect to be making more money later in life, you will be in a higher tax bracket if the laws don’t change, so this would be a reason to give later. The other factor is that there is a standard deduction of around $6,200. So unless you own a house (and therefore are deducting the interest payments), you actually have to give a lot of money away first with no tax benefit. This is another reason to delay giving (if you eventually plan to own a house).
