How Much Tolerance Is Enough?

When designing circuits, is there a rule of thumb for picking voltages and tolerances of components? For example, if my power source is 12 volts, is an electrolytic capacitor with a 24V rating  “better” than one with a 16V rating? What do good designers use as a margin?
