So A Penny a Day or One Million Up Front? What Did You Choose?

Let’s start with this question – Would you rather have a penny today, that doubled everyday for a month, or $1 million today?

Let’s break this down with a bit of math to see which option ends up giving you more money by the end of a 30-day month.

Option 1: You start with a penny, and it doubles every day for 30 days.

  • Day 1: $0.01
  • Day 2: $0.02
  • Day 3: $0.04
  • Day 30: ?

Option 2: You receive $1 million upfront.

To calculate the total amount for Option 1, we can use the formula for exponential growth, which in this case is 0.01×2(�−1)0.01×2(n−1), where �n is the day number. Let’s calculate the value for day 30.

By the end of the 30th day, if you started with a penny that doubled every day, you would have $5,368,709.12.

Comparing the two options:

  • Option 1 (penny doubled every day for a month): $5,368,709.12
  • Option 2 ($1 million today): $1,000,000

Therefore, you would be better off choosing the penny that doubles every day for a month over receiving $1 million today.


  1. The first U.S. penny was minted in 1787 and was designed by Benjamin Franklin.
  2. Pennies were originally made from copper but now are mostly zinc with a thin copper coating.
  3. The Lincoln penny was the first U.S. coin to feature a historical figure.
  4. If you have a 1943 copper penny, it could be worth up to $85,000 because most pennies that year were made of steel.

  • Only be able to use pennies to pay for things for a day or only $100 bills?
