Present worth 1. Converts all cash flows to a single sum equivalent at t= ( planning horizon) u sing i= MARR 2. Converts all cash flows to a single sum equivalent at t=0 using i= MARR 3. Converts all cash flows to an equivalent uniform series over the planning horizon 4. Determines an interest rate that yields a PW (or FW or AW) of 0 5. Determines how long it takes for the cumulative present worth to be positive at i= MARR 6. Determines the interest rate that equates the future worth of invested capital to the future worth of recovered capital invested at i = MARR 7. Determines the PW when the planning horizon is infinitely long
