sidereal year

(noun)

The orbital period of the Earth; a measure of the time it takes for the Sun to return to the same position with respect to the stars of the celestial sphere. A sidereal year is about 20.4 minutes longer than the tropical year due to precession of the equinoxes.

  • Calculating the Payback Period

    • Payback period is usually expressed in years.
    • Start by calculating Net Cash Flow for each year: Net Cash Flow Year 1 = Cash Inflow Year 1 - Cash Outflow Year 1.
    • Then Cumulative Cash Flow = (Net Cash Flow Year 1 + Net Cash Flow Year 2 + Net Cash Flow Year 3 ... etc.)
    • Accumulate by year until Cumulative Cash Flow is a positive number: that year is the payback year.
    • Year 0: -1000, year 1: 4000, year 2: -5000, year 3: 6000, year 4: -6000, year 5: 7000.

  • Disinflation

    • The economy is experiencing disinflation because inflation did not increase as quickly in Year 2 as it did in Year 1, but the general price level is still rising.
    • Assume the following annual price levels as compared to the prices in year 1:
    • As the economy moves through Year 1 to Year 4, there is a continued growth in the price level.
    • However, between Year 2 and Year 4, the rise in price levels slows down.
    • Between Year 2 and Year 3, the price level only increases by two percentage points, which is lower than the four percentage point increase between Years 1 and 2.

  • Dollar Returns

    • Finding the dollar return for securities that trade in open markets is a matter of finding the difference in price from year to year.
    • At the end of year 1, it is worth $105, which is $5 more than $100 (its value at the beginning of year 1), so the dollar return is $5.
    • The capital value at the end of year 2 is $110.25, which is $5.25 more than at the end of year 1, and $10.25 more than at the beginning of year 1.
    • This continues for each successive year.
    • The dollar return is the difference in value from year to year, plus the previous dollar return.

  • Defining the Payback Method

    • A $1000 investment which returned $500 per year would have a two year payback period.
    • The payback period is usually expressed in years.
    • Start by calculating net cash flow for each year: net cash flow year one = cash inflow year one - cash outflow year one.
    • Then cumulative cash flow = (net cash flow year one + net cash flow year two + net cash flow year three).
    • Accumulate by year until cumulative cash flow is a positive number, which will be the payback year.
