# Why's it always better to choose a lump sum than periodic payments over time?

1. True or False? It is always better to choose a lump sum than periodic payments over time.

Doesn't the answer depend on the amount of lump sum vs. periodic payments and inflation?

Or are the authors assuming that if lump sum = P, then you get n periodic payments of $$\frac{P}{n}$$ (for a total of $$n × \frac{P}{n}$$)? Then inflation will cause each P/n to be worth less.

• If the question did not provide more information, then you are correct in your doubts. For example, it is not better to choose a single lump sum of \$1 than monthly payments of \$100, so that the given statement is false. – Kenny LJ Jul 30 '19 at 6:13
• +1 for @KennyLJ. My guess is that the author is assuming, as you said, the sum of periodic payment is equal to lump sum payment. – Art Jul 30 '19 at 8:43
• The author probably also ignored the possibility of negative interest rates. Tssk. – Brian Romanchuk Jul 30 '19 at 11:00
