A sum, not advice. It divides the amount by the spending. The amount earns nothing and prices stay the same.

How this is worked out

A year is counted as 365.25 days, which is 31,557,600 seconds, and a month as one twelfth of a year. Nothing is estimated or forecast.

How the calculator works

It is one division. The amount is divided by the spending, which gives the number of seconds, days, weeks, months or years the amount lasts. That is then turned into years and days, counting a year as 365.25 days. The second table on the calculator runs the sum the other way: the amount divided by a length of time, which gives the spending needed to finish in that time.

The amount earns nothing while it is being spent, nothing is taken off it and prices do not change. Real money does not behave like that, so this is the size of a number and not a plan for anybody.
