| <p>If we graph the interest rates we get:</p> | ||
| <p><img src="/images/2018/03/rates.en.png" alt="Interest rates over time" /></p> | ||
| <p>You can see a clear peak in the variable rate when the riksbank set | ||
| the repo rate at 500% (mortgages “only” reached 24%). You can also see | ||
| that during the early nineties the variable rate was higher than the | ||
| fixed rates during relatively long periods. But to compare the actual | ||
| cost over the fixed term we have to compare average rates.</p> | ||
| <p>For example, let us compare the actual average rates from the first of | ||
| July 1991 during 5 years for variable rate (11.96%) and 5 years fixed | ||
| term (12.25%). Even though with variable rate you’d have had a rate of | ||
| 24% during a quarter you’d still pay less in total over the 5 years.</p> | ||
| <p>If the same calculation is made for every month you can see how much | ||
| you would have earned/lost depending on when you started your fixed | ||
| term. Since 5 years is not evenly divisible by 2 years, the 2 years | ||
| fixed term refers to what the average rate would have been during the | ||
| first 5 of the 6 years.</p> | ||
| <p><img src="/images/2018/03/5y_avg_rates.en.png" alt="Average interest rate over 5 years" /></p> | ||
| <p>It’s quite clear that variable rate has nearly always been the most | ||
| profitable alternative. At three seperate occasions it would have been | ||
| more profitable to pick a 5 year fixed term: at the of 1989, the | ||
| beginning of 1997, and in the middle of 2005. I won’t comment on the 2 | ||
| years fixed term since it’s not a fair comparison to only look at 5 out of | ||
| 6 years.</p> | ||
| <p>If we compare 2 years fixed term with variable rate:</p> | ||
| <p><img src="/images/2018/03/2y_avg_rates.en.png" alt="Average interest rate over 2 years" /></p> | ||
| <p>Also here the most profitable choice is generally the variable rate | ||
| however during times of rising interest rates getting a fixed 2 year | ||
| term has been the better choice on several occasions. An important | ||
| difference to the 5 years term is that you’re not locked in for long | ||
| when the rates finally go down again (and you’re able to switch to | ||
| variable rate).</p> | ||
| <p>If we compare all terms during 10 years:</p> | ||
| <p><img src="/images/2018/03/10y_avg_rates.en.png" alt="Average interest rate over 10 years" /></p> | ||
| <p>Here it is clear that the variable rate is the most profitable.</p> | ||
| <p>Even though it has been possible at certain occasions (29 years and | ||
| only 3 short occasions!) to get a fixed term for 5 years and pay less | ||
| overall than with variable rate, I think it’s far too improbable that | ||
| one is able to do it at the right time. You’re almost guaranteed to be | ||
| paying more in the end.</p> | ||
| <p>Getting a fixed term for 2 years is more probable to be profitable, | ||
| but even here it is more probable not to be.</p> | ||

| <p>When you have apps in Google Play (and I imagine, other App stores as well), the amount of spam you receive instantly goes up by a factor of 10. Google’s spam filters are pretty well trained but every now and again something gets through.</p> | ||
| <h2 id="advertising-opportunity">Advertising opportunity</h2> | ||
| <p>Today’s piece of bullshyt (I really meant to spell it like that) reads as follows (my emphasis):</p> | ||
| <blockquote> | ||
| <p>Our premium advertisers are currently looking to buy android traffic at a very high price in apps like Nononsense Notes.</p> | ||
| <p>We think you can generate up to $10 CPM with their <strong>full screen ads</strong>, which are <strong>very clean</strong>. Indeed, most of our advertisers are willing to pay, on average, between $1 and $3 per installation. You’re free to display these ads whenever you want in your app so that it’s <strong>not intrusive</strong>.</p> | ||
| </blockquote> | ||
| <p>Ads are by definition <em>intrusive</em>. That’s how they nag you into buying their stupid stuff. And it doesn’t matter how clean your ads are. Displaying them fullscreen is <em>beyond</em> intrusive. It is down right <strong>offensive</strong>.</p> | ||
| <p>I uninstall anything that displays obnoxious ads, be they fullscreen or notifications, and promptly give the app a one star review. I sincerely hope others afford me the same “courtesy” for my apps.</p> | ||
