At age 62, you receive 75% of what you’d receive at your full retirement age (assuming 66). If you delay until 70 years old, you accrue 8% more per year (32% over 4 years).
In general, I usually recommend waiting until 70 to start your social security, but this is also assuming a long life.
When you’re looking at social security planning for couples, I have a program on my computer that can track all the permutations (file and suspend, delay, spousal benefits), etc.
