What does inflation mean to me?
"Inflation as defined in the general, has many impacts at a personal level. For example, you say that the reduction in the price of oil has no impact on you.  That's absolutely not true, unless you're a hermit living off of the land.  Every box or can or jar of food you buy off the shelf of the grocery store has the price of oil baked into it, because it had to get there somehow.  High fuel costs for trucks mean increased costs to put food on shelves, which mean increased prices for that food. Even tobacco prices can affect you, because they affect what other people are spending.  Demand is always a significant factor in prices, particularly retail prices, and if people are spending more money on tobacco, they're probably spending less on other things - either buying less snacks, for example, or buying cheaper brands of those snacks.  So the price of Doritos may drop a bit (or not rise), for example. General inflation also tends to drive raises, particularly in industries with relatively small performance ties to raises.  If inflation is 3%, wages need to raise 3% or so in order to keep up, on average; even if your personal cost-of-living went up 0%, or 5%, or 10%, the default wage inflation will be closer to that of the national average.  Any raise less than national average is effectively a pay cut (which is one reason why inflation is needed in a healthy economy).  So your company probably has a cost-of-living raise everyone gets that's a bit less than inflation, and then good performers get a bump up to a bit more than inflation.  You can read more on this topic for a more in-depth explanation. Finally, inflation rates tend to be major factors in stock market movement.  Inflation that is too high, or too low, can lead to higher volatility; inflation that is ""right"" can lead to higher stability.  An economy that has consistently ""right"" inflation (around 2-3% typically) will tend to have more stable stock market in general, and thus more reliable returns from that market.  There are many other factors that lead to stock markets rising and falling, but inflation is one very relevant one, particularly if it's not in the ""right"" zone." Inflation data is a general barometer for inflation that a typical consumer would experience.  Generally when calculating inflation for yourself you would only include items that you use and in percentages of your budget.   Personal inflation is much more useful when attempting to calculate safe withdrawal rates or projections into the future. The general discussion of inflation centers on money as a medium of exchange and a store of value. It is impossible to discuss inflation without considering time, since it is a comparison between the balance between money and goods at two points in time. The whole point of using money, rather than bartering goods, is to have a medium of exchange. Having money, you are interested in the buying power of the money in general more than the relative price of a specific commodity. If some supply distortion causes a shortage of tobacco, or gasoline, or rental properties, the price of each will go up. However, if the amount of circulating money is doubled, the price of everything will be bid up because there is more money chasing the same amount of wealth. The persons who get to introduce the additional circulating money will win at the expense of those who already hold cash. Most of the public measures that are used to describe the economy are highly suspect. For example, during the 90s, the federal government ceased using a constant market basket when computing CPI, allowing substitutions. With this, it was no longer possible to make consistent comparisons over time. The so-called Core CPI is even worse, as it excludes food and energy, which is fine provided you don't eat anything or use any energy. Therefore, when discussing CPI, it is important to understand what exactly is being measured and how. Most published statistics understate inflation. It means that your money does not have the same amount of buying power. "Everyone buys different kinds of goods. For example I don't smoke tobacco so I'm not affected by increased tobacco prices. I also don't have a car so I'm not affected by the reduced oil prices either. But my landlord increased the monthly fee of the apartment so my cost of living per month suddenly increased more than 10% relative to the same month a year before.  This is well known, also by the statistical offices. As you say, the niveau of the rent is not only time- but also location specific, so there are separate rent indices (German: Mietspiegel). But also for the general consumer price indices at least in my country (Germany) statistics are kept for different categories of things as well.  So, the German Federal Statistical Office (Statistisches Bundesamt) not only publishes ""the"" consumer price index for the standard consumer basket, but also consumer price indices  for oil, gas, rents, food, public transport, ... Nowadays, they even have a web site where you can put in your personal weighting for these topics and look at ""your"" inflation:  https://www.destatis.de/DE/Service/InteraktiveAnwendungen/InflationsrechnerSVG.svg Maybe something similar is available for your country?" "short answer:  any long term financial planning (~10yrs+). e.g. mortgage and retirement planning.  long answer: inflation doesn't really matter in short time frames. on any given day, you might get a rent hike, or a raise, or the grocery store might have a sale.  inflation is really only relevant over the long term.  annual inflation is tiny (2~4%) compared to large unexpected expenses(5-10%).  however, over 10 years, even your ""large unexpected expenses"" will still average out to a small fraction of your spending (5~10%) compared to the impact of compounded inflation (30~40%). inflation is really critical when you are trying to plan for retirement, which you should start doing when you get your first job.  when making long-term projections, you need to consider not only your expected nominal rate of investment return (e.g. 7%) but also subtract the expected rate of inflation (e.g. 3%). alternatively, you can add the inflation rate to your projected spending (being sure to compound year-over-year). when projecting your income 10+ years out, you can use inflation to estimate your annual raises.  up to age 30, people tend to get raises that exceed inflation. thereafter, they tend to track inflation. if you ever decide to buy a house, you need to consider the impact of inflation when calculating the total cost over a 30-yr mortgage. generally, you can expect your house to appreciate over 30 years in line with inflation (possibly more in an urban area). so a simple mortgage projection needs to account for interest, inflation, maintenance, insurance and closing costs. you could also consider inflation for things like rent and income, but only over several years. generally, rent and income are such large amounts of money it is worth your time to research specific alternatives rather than just guessing what market rates are this year based on average inflation. while it is true that rent and wages go up in line with inflation in the long run, you can make a lot of money in the short run if you keep an eye on market rates every year. over 10-20 years your personal rate of inflation should be very close to the average rate when you consider all your spending (housing, food, energy, clothing, etc.)."
Inflation is basically this:  Over time, prices go up! I will now address the 3 points you have listed. Suppose over a period of 10 years, prices have doubled.  Now suppose 10 years ago I earned $100 and bought a nice pair of shoes.  Now today because prices have doubled I would have to earn $200 in order to afford the same pair of shoes.  Thus if I want to compare my earnings this year to 10 years ago, I will need to adjust for the price of goods going up.  That is, I could say that my $100 earnings 10 years ago is the same as having earned $200 today, or alternatively I could say that my earnings of $200 today is equivalent to having earned $100 10 years ago. This is a difficult question because a car is a depreciating asset, which means the real value of the car will go down in value over time. Let us suppose that inflation doesn't exist and the car you bought for $100 today will depreciate to $90 after 1 year (a 10% depreciation). But because inflation does exist, and all prices will be 0.5% higher in 1 years time, we can calculate the true selling price of the car 1 in year as follows: 0.5% of $90 = 0.005*90 = $0.45 Therefore the car will be $90 + $0.45 = $90.45 in 1 years time. If inflation is low, then the repayments do not get much easier to pay back over time because wages have not risen by as much.  Similarly the value of your underlying asset will not increase in value by as much. However as compensation, the interest rates on loans are usually lower when inflation is lower. Therefore generally it is better to get a loan in times of high inflation rather than low inflation, however it really depends on how the much the interest rates are relative to the inflation rate. &gt; Never said that.  Huh?  Did you NOT say:  * Governments **taxing** people people too much that's causing deflation.  I mean, there are some out there who claim that it's *inflation* that is fiscal. While I also think that's an interesting and particular theory, the theory that *deflation* is fiscal is a view that one just doesn't encounter often. Which is why I'm interested in seeing what sort of sources and/or evidence this theory flows from.   &gt; You don't **believe** taxes are deflationary?  You're asking me what I believe in? I believe in the old-school, neoclassical view on the matter. "I'd question whether a guaranteed savings instrument underperforming the stock market really is a risk, or not?  Rather, you reap what you sow. There's a trade-off, and one makes a choice.  If one chooses to invest in a highly conservative, low-risk asset class, then one should expect lower returns from it.  That doesn't necessarily mean the return will be lower — stock markets could tank and a CD could look brilliant in hindsight — but one should expect lower returns.  This is what we learn from the risk-return spectrum and Modern Portfolio Theory. You've mentioned and discounted inflation risk already, and that would've been one I'd mention with respect to guaranteed savings. Yet, one still accepts inflation risk in choosing the 3% CD, because inflation isn't known in advance.  If inflation happened to be 2% after the fact, that just means the risk didn't materialize.  But, inflation could have been, say, 4%. Nevertheless, I'll try and describe the phenomenon of significantly underperforming a portfolio with more higher-risk assets.  I'd suggest one of: Perhaps we can sum those up as: the risk of ""investing illiteracy""? Alternatively, if one were actually fully aware of the risk-reward spectrum and MPT and still chose an excessive amount of low-risk investments (such that one wouldn't be able to attain reasonable investing goals), then I'd probably file the risk under psychological risk, e.g. overly cautious / excessive risk aversion. Yet, the term ""psychological risk"", with respect to investing, encompasses other situations as well (e.g. chasing high returns.) FWIW, the risk of underperformance also came to mind, but I think that's mostly used to describe the risk of choosing, say, an actively-managed fund (or individual stocks) over a passive benchmark index investment more likely to match market returns." "There has been almost no inflation during 2014-2015. do you mean rental price inflation or overall inflation? Housing price and by extension rental price inflation is usually much higher than the ""basket of goods"" CPI or RPI numbers. The low levels of these two indicators are mostly caused by technology, oil and food price deflation (at least in the US, UK, and Europe) outweighing other inflation. My slightly biased (I've just moved to a new rental property) and entirely London-centric empirical evidence suggests that 5% is quite a low figure for house price inflation and therefore also rental inflation. Your landlord will also try to get as much for the property as he can so look around for similar properties and work out what a market rate might be (within tolerances of course) and negotiate based on that. For the new asked price I could get a similar apartment in similar condos with gym and pool (this one doesn't have anything) or in a way better area (closer to supermarkets, restaurants, etc). suggests that you have already started on this and that the landlord is trying to artificially inflate rents. If you can afford the extra 5% and these similar but better appointed places are at that price why not move? It sounds like the reason that you are looking to stay on in this apartment is either familiarity or loyalty to the landlord so it may be time to benefit from a move." In short, if your expenses rise with inflation but your income does not, your expenses will eventually exceed your income. As the article on perpetuities says, a perpetuity is an annuity that pays forever.  An annuity is a financial arrangement whereby you are paid a fixed sum every so often for a period of time.  Hence, a perpetuity is an arrangement whereby you are paid a fixed sum every so often until you die.  Since the sum is fixed in nominal dollars (or other currency units), it will become worth less and less in real dollars as time goes on, which is what will erode your financial independence. To adapt the example from the article that you quote: If you buy an annuity that will pay you $101 per month and your expenses are $100 per month, you may seem to be financially independent.  However, if inflation is 2% per year, then next year your expenses will be $102, but the annuity will still only pay you $100.  At that point you will no longer be financially independent, since the annuity no longer covers your expenses. There are some senses in which the article's statement is inaccurate in practical terms --- e.g., annuities need not always have fixed payments but may be adjusted for inflation, also there aren't many real perpetuities in existence anyway, and plus it doesn't matter whether the source of the income is an annuity or something else --- but that is the gist of what the article is saying. Inflation is what happens, it is not good or bad in and of itself.  But consider the following. In a thriving economy with low unemployment, people are buying, buying, buying.  People are not saving for later, they are buying now.  Industry is also making purchases.  Now.  From economics 101: high demand for goods/services leads to relative scarcity leading to higher prices.  Inflation tends to be one byproduct of a thriving economy.  Governments want the thriving economy that brings inflation with it. There are two things you need to keep in mind when you look at Inflation as an entity. Inflation is necessary to keep in check the value of goods. As per Moore's Law for example, a mobile phone that you buy for £100 today will be available for £50 in two years. With increased purchasing power, one needs to maintain balance between the purchasing power and its value. If you think about the 'loss' at a rate of 2% you would have £96.04 (in terms of today's value) in two years. But if you looked at the same cell phone as leverage for your business where it allowed you to do work and earn £1000 in two years - the investment would clearly offset the cost of inflation. Inflation is incentive for people to spend their money. If you for example spent all of your £100 today, it is £100 income for someone else. He has further incentive to spend it creating a chain of transactions. In theory while this is a true mathematical loss, the increasing purchasing power helps you leverage your financial asset to get a return on your investment. Or I am in it for the long hall and am full expecting it to go down again. Probably two or three more times before I retire. Just gotta ride it out and have a stomach for when it goes down. Stick to the plan because history always repeats itself. I think 2007 showed us anything is that the governments will risk massive inflation before it lets the market fail. And if inflation hits you want your money wrapped up in the market to grow at the correct rate.
