### Present Worth Analysis

This is just using the Present Worth Factor.

You need to be very careful because both alternatives have different service lives (pages 17-19 show the wrong calculations). **We need to apply the repeated lives method** to get a fair comparison.

### Future Worth Analysis

This is just using the Compound Amount Factor.

Example is super similar, just need to be careful to wrap your head around the calculation.

- Everything is relative to the future, so you don’t need to worry about calculating in terms of the present. This was confusing to me for the $15,000 cost

#### Capitalized Cost Analysis

This is so easy. It’s basically the Series Present Worth Factor where $N→∞$.

### Annual Worth Analysis

The AW, or Equivalent Uniform Annual Worth (EUAW), represents a measure of project profitability as an equivalent annual value.

This is basically using Capital Recovery Factor.
