ၽိုၼ်ၵႅမ်မိုဝ်းထႅမ်းပလဵတ်ႉ[တူၺ်း] [မႄးထတ်း] [ပိုၼ်း] [ၸၢင်း]

This template calculates inflation based on several inflation index data sets. The template uses an identification code for an inflation index (usually a country code), an original value, an original start_year and either a specific reference end_year or by default the latest currently available end year, and calculates the equivalent value from historical economic changes between the original and reference years. For example, this template calls the United States inflation table located in the sub-template Template:Inflation/US/dataset to perform the U.S. calculation.

Aside from a convenient way to calculate values from different specified time periods, this template allows a regularly automatically updated calculation of value based on the most recent available inflation data. Whenever inflation tables are updated, potentially annually, all articles using this template have their displayed values updated accordingly.

• |index= (parameter 1), required, an index code for one of several available inflation indexes.
• |value= (parameter 2), required, original price or value from which to base the inflation calculation on. Will ignore any commas, but must not have a currency symbol.
• |start_year= (parameter 3), required, original year from which to base the inflation calculation on. Must be a year available in the chosen inflation index. As an exception to this, if the current year is specified and no end_year is specified, the template will output value unchanged, as it can be assumed an inflation of zero.
• |end_year= (parameter 4), optional, reference year for which to calculate inflation. Must be higher (later) than start_year, but not higher than the highest (most recent) year available in the chosen inflation index, and will default to the highest (most recent) available year if omitted.
• |r=digit sets the digits to which the value must be rounded. A negative value indicates rounding to an upper significant digit, and a positive value indicates a fractional digit including trailing zeros. Defaults to 0, i.e., without cents.
• |fmt=c will insert thousands separator commas into the calculated value.
• |fmt=eq will show an equivalent-to phrase, in the format, "equivalent to cursignend_value in end_year". Uses thousands separator commas.
  • |cursign= will set the currency symbol to be shown. Only functions when |fmt=eq is used. Can use advanced symbol formats, but can only precede the calculated value. Default is $.
  • |orig=yes will display the original value too, with the currency sign provided.

Tips & tricks

Currency conversion

Many datasets are currency agnostic, which means they don't convert between different currencies. Thus, if you wanted to know today's equivalent value of 1,000.00 Austrian schillings in 1960, entering {{Inflation|AT|1000|1960|r=2}} would provide a result (6550.14) still in schillings, not in euros.

Consequently, if you need a result in a currency other than the one in which the original value is stated, for now you must do the conversion manually, as in the following example which uses the defined conversion rate of 13.7603 schillings to one Euro:

• Y {{#expr:({{Inflation|AT|1000|1960|r=2}} / 13.7603) round 2}} → 476.02

Instead of manually inputting a conversion for the Euro from a national currency, it is possible to divide by {{FixedEuroRate}} instead.

Some datasets are not currency agnostic; check the sources for each dataset to determine this.

 တႃႇႁဵတ်း A currency conversion template to ease these conversion tasks is planned. This section will be updated accordingly once it's developed.

Non-decimal inputs

The template does not accept non-decimal inputs such as £sd; these must be decimalized beforehand. For example, if you wanted to know the value of three shillings and sixpence (3s 6d) Sterling in 1950 in 2018, you must convert to the appropriate decimal value (in this case £0.175) for use in the template:

• Y {{Inflation|GBP|0.175|1950|2018}} →

For £sd specifically {{Pounds, shillings, and pence}} can be used to convert to decimal. For other non-decimal currencies, such as the old Indian rupee, templates can be made for decimalization upon request.

• Y {{Inflation|GBP|{{Pounds, shillings, and pence|s=3|d=6}}|1950|2018|r=0|fmt=eq|cursign=£}} → equivalent to £6 in 2018

• Y {{Inflation|UK|{{Pounds, shillings, and pence|s=10|d=6}}|1865|fmt=eq|cursign=£}} → equivalent to £54 in 2021

Rounding

By default the values are calculated to the unit, as for all but very low values cents are undesirable. You can specify rounding with the |r= parameter which determines the number of decimals. To obtain cents use |r=2, but other values can be used, including negative ones: |r=-3, for example, will round to the nearest thousand, |r=-6 to the nearest million, and so on. It is advisable to avoid false precision; even if the start value is known to be exact, the template's result will not be because the inflation index tables are rarely accurate to more than about 1%, and a granularity of whole years is used.

Very large results

Very large results are expressed in scientific notation ("1.2E+14" instead of "120000000000000") which is normally not desirable. A workaround is to express the value to be inflated with fewer digits, adding a multiplier text such as "trillion" after the result, using the "Show preview" button as many times as needed, changing parameters until the best result is found:

• Y ${{Inflation|US-GDP|1000000000000|1900|r=-11|fmt=c}} → $27,100,000,000,000
• N ${{Inflation|US-GDP|10000000000000|1900|r=-12|fmt=c}} → $271,000,000,000,000
• N ${{Inflation|US-GDP|10000000000|1900|r=-9|fmt=c}} thousand → $271,000,000,000 thousand
• Y ${{Inflation|US-GDP|10000000|1900|r=-6|fmt=c}} million → $271,000,000 million
• Y ${{Inflation|US-GDP|10000|1900|r=-3|fmt=c}} billion → $271,000 billion
• Y ${{Inflation|US-GDP|10|1900|fmt=c}} trillion → $271 trillion

The following section provides an automated way of avoiding this trial and error scenario.

Format price

{{Format price}} is a template specifically designed to display price values, both big and small, in a readable way. For example, instead of showing the whole of a huge number such as "953,783,409,856.12", it would show it as "954 billion", while small numbers have their cents part appearing as expected, "1234.5" being properly shown as "1,235".

• Y ${{Format price|{{Inflation|US-GDP|10000000000000|1900}}}} → $271 trillion
• Y ${{Format price|{{Inflation|US-GDP|1000000|1990}}}} → $1.86 million
• Y DM {{Format price|{{Inflation|DE|1000000|1957|1978}}}} → DM 2.01 million
• Y £{{Format price|{{Inflation|UK-GDP|1000|1323}}}} → £699,508

Citing inflation data sources

It's a good practice to provide a valid reference for the prices calculated with this template in articles where it's used. The template {{Inflation/fn}} was developed to ease this task. It accepts as its single parameter the same country codes used here, and will generate one or more appropriate footnotes. Typically, this is how a piece of text using it looks like:

• In 1985 a unit cost on average $1,040. This is {{Inflation|US|1040|1985|fmt=eq}}.{{Inflation/fn|US}}

Resulting in this converted code (notice the footnote link at the end):

• In 1985 a unit cost on average $1,040. This is equivalent to $2,830 in 2022.

The footnote thus generated appears whenever {{reflist}} or <references /> is used in an article, usually in its "References" section. See below for the live example in this document's own References section, or click the above generated footnote to jump to it.

Limitations

1. Currently it isn't possible to "de-inflate" a value to what it would have been in a previous year. If you need this functionality, please request it at the talk page. Adding it won't be difficult, but there's no point in doing so before someone actually needs it.
2. Substitution isn't supported at all. Trying to {{subst:Inflation|...}} would only result in a long sequence of embedded parser code without any direct benefit. If you need to obtain an inflated price only once, please use the special ExpandTemplates page then copy the result and paste it at the desired location.

Inflation

This template calculates inflation based on several inflation index data sets. Note that this template defaults to calculating the inflation of Consumer Price Index values: staples, workers' rent, small service bills (doctor's costs, train tickets). For inflating capital expenses, government expenses, or the personal wealth and expenditure of the rich, the US-GDP or UK-GDP indexes should be used, which calculate inflation based on the [[gross domestic product]] (GDP) for the [[United States]] and [[United Kingdom]], respectively.

Template parameters[ၸတ်းၵၢၼ် ၶေႃႈမုၼ်းထႅမ်းပလဵၵ်ႉ]
