When you put some money into an investment, there is always risk of losing the money no matter what. How many percent of your regular income can you afford to lose on investment programs?
Well, I make not so much money from my job. You can say that it's just enough to make ends meet. I think I can afford not more than 10% of my monthly income for investment.
I put money into the stock market through my work and the 401K plan. It's the only money that I put in. I believe it's 5% of my income and my employer matches 2.5%.
It could depend entirely on what I am investing in, or the year. Some years are better than others. This year for example we have our money tied up elsewhere so there are no extras going around this time, maybe next year though.
We have a little bit invested through my husband's 401k at work but it's not very much and as it's our only retirement plan we can't really afford to lose any of it.
