No matter the size of your income, you can make provisions for, emergency funds, reserve and float. All you have to do is just assign a certain percentage to all of the funds you are to keep aside, you can say emergency funds will get 5% of your monthly income, 10% will go to reserve funds, 20% investment and so on. If you can be able to put everything in percentage it will be a bit easier for you. Immediately your salary comes in you will know before hand how much you are putting in each funds account. You can't say your salary is too small and neglect to make provisions for any of the funds which you are expected to set aside, if you do it your investment will be tempared with on the long run. No matter the range of your salary, please always make provisions for emergency funds, reserve and float. It will save you lots of troubles in the future.
This is exactly how I do it, I have a % allocation of my disposable income that gets split up into the different places. The one thing to note, and most people don't do this but its a good practice to do is when your emergency fund is fully funded you should continue to add % based on the inflation rate in your country. This is ensure the buying power stays relative to your market. 3 months is good place to start as coverage for your emergency fund, and then you got options to go to 6,12,15,18 months etc. I personally capped it out at 18 months, but have been doing this a long time, 3-6months can usually deal with most things to be honest.
% based division of disposable income is nice too, because when you get a salary increase or even like "bonus" or "unexpected windfall" you can apply the same % divisions to spread it out into your different places.
Keep stacking
It may be a good decision to withdraw yourself from waste when you know you have to continue through the holding.
Yes this is inevitable truth but it can effectively work when the money you have is sufficient in all side of life, apart from emergency fund other fund is already outstanding for others purposes, if some money one has has nothing to be assigned for and stand to be static with yielding any interest the best is to invest it where it will give income at the stipulated period of time either by increasing the existing investment, but where as such money mat need augent need no need to force it into an investment where it will not be long to withdraw because what we are dealing with us Long time issue. And one most important thing to note is that if your running for Long time investment one should avoid over investing because that can leads to cutting short the investment except you have weigh your source of income can carry no matter how your stretch it won't affect the investment to be cut short.
