How to use a retirement savings goal calculator?

Usage of this tool is pretty simple, but in order to avoid any misunderstanding below we are describing each field with some useful saving tips.

Goal amount

Here you should type the amount of money you need to have to be able to retire early.  If you have no idea you may use this calculator to estimate the amount needed for your retirement.

Initial amount

If you already have some savings, type this amount into this field. The calculator will treat them as a seed investment and will take them into account while calculating interests earned each month.

Monthly savings

Here you should type the amount of money you are willing to save each month. 

Annual increase

Our tool could take into account your potential pay rises. So in order to be more realistic, type in here some percentage that will simulate your future salary increases. 

Interest rate

Thanks to the compound interest you may reach your goal faster. Type here the average annual return rate you expect to make on your investments. Try not to be over optimistic and stick to the average return rates the different asset classes may provide. 


The compounding frequency determines how often the interests earned are added to the savings balance. Our retirement goal calculator will allow you to choose between: monthly, quarterly, annually compounding frequency.  

Tax rate

The income tax rate for your interest earnings. If you save using a tax protected plan like 401k or similar you may type here 0%. 

How much money do I need to retire early?

The simple answer is that you need to have a portfolio of assets able to generate enough interest each month to cover all your living expenses like housing, food, bills etc.

What’s more, most financial advisors suggest that you should calculate such a number using a 4% interest rate or even less. 

If you follow this rule you may never run out of money during your retirement. However people that are about to retire later in their 50s or 60s may live not just from the interests earnestly but from accumulated capital as well.
