What is a Constant Dollar?

A steady dollar is an adjusted value of currency used to compare dollar values starting with one period then onto the next. Due to inflation, the purchasing power of the dollar changes after some time, so to compare dollar values over time one year to another, they should be changed over from nominal (current) dollar values to steady dollar values. Consistent dollar value may likewise be alluded to as real dollar value.

Steady dollar calculation:
Second Year Constant Dollar Value=FYDV×CPI2CPI1where:FYDV=First year dollar valueCPI2=Consumer price index for second yearCPI1=Consumer price index for first year\begin &\text = \text \times \frac { \text_2 }{ \text_1 } \ &\textbf \ &\text = \text \ &\text_2 = \text \ &\text_1 = \text \ \end

Fundamentals of Constant Dollars

The consistent dollar is frequently utilized by companies to compare their recent performance to past performance. States additionally utilize the steady dollar to follow changes in economic indicators, like wages or GDP. Any sort of financial data addressed in dollar terms can be changed over into steady dollars by utilizing the consumer price index (CPI) from the significant years.

People can likewise utilize consistent dollars to measure the true appreciation of their investments. For instance, When calculated in a similar currency, the possibly case when a steady dollar value is higher in the past than the present is the point at which a country has encountered deflation over that period.

Illustration of Constant Dollars

Consistent dollars can be utilized to work out what $20,000 earned in 1995 would be equivalent to in 2005. The CPIs for the two years are 152.4 and 195.3, individually. The value of $20,000 in 1995 would be equivalent to $25,629.92 in 2005. This is calculated as $20,000 x (195.3/152.4). The calculation should likewise be possible in reverse by turning around the numerator and denominator. Doing so uncovers that $20,000 in 2005 was equivalent to just $15,606.76 in 1995.

Assume Eric bought a house in 1992 for $200,000 and sold it in 2012 for $230,000. In the wake of paying his real estate agent a 6% commission, he's left with $216,200. Taking a gander at the nominal dollar figures, apparently Eric has made $16,200. However, what happens when we change the $200,000 purchase price to 2012 dollars? By utilizing a CPI inflation calculator, we discover that the purchase price of $200,000 in 1992 is the equivalent of $327,290 in 2012. By contrasting the steady dollar figures, we discover that Eric has basically lost $111,090 on the sale of his home.
