Expected annual return calculators

S & P 500 calculator

What & How

Starting from:

• what can you expect – long term – from various assets or market indices / ETFs – see post here
• what do I estimate as a correct price level – see post here

I combined these two to make the calculators below. The formulas built into the calculators are not difficult. For example, the S & P 500 index:

• my estimate fair price level (end of 2018) is 2200 – see post here
• the historical growth rate is 8.7 % – see post here
• which means that a fair price level for the S & P 500 in 5 years will be 2200 x (1.087) 5 = 3339

From that number, you can easily calculate back the annual returns over a 5 – year period starting from any given number.

• For instance, starting from 2600 today, you get a return of (3335 / 2600) 1 / 5 – 1 = 5.1 % annually. That is a Total Return (including reinvested dividends and excluding inflation adjustment and excluding any expenses and taxes).
• Simple test: what is the expected annual return for a starting index of 2200?
• (3335 / 2200) 1 / 5 – 1 = 8.7 % annually. Duh! which was to be expected, since we start from the ‘fair index level’ 2200 we can also expect the average annual return of 8.7 %.

The other calculators apply the same simple logic.

I do not pretend that the outcome is exact, nor that I predict the future. But they are useful to have an indication of what can be expected. When the S&P 500 goes to 2940, as it went in August 2018, the calulator says that your returns will be 3% dividend included. When the market goes to 2346 as in December 2018, the calculator says 7 % annually. It gives you a good indication when to move more savings into an ETF and when preferably not to add money.
