Focus on the big picture, get a savings account with a good interest rate and try and set aside a certain amount of money each month. Even if you’re only putting in $50 a month, it still adds up over the course of a few years. Figuring out just how much you’ll have put into saving, but figuring out how much you’ll have made from interest is somewhat more time consuming, so here’s a simple way to figure out just how much money you might save over an extended period of time.

function calculate(form) { var startVal = eval(form.startVal.value) * 1.0; var addVal = eval(form.addVal.value) * 1.0; var years = eval(form.years.value) * 1.0; var frequency = eval(form.frequency.value); var compounded = eval(form.compounded.value); var interest = eval(form.interest.value); if (interest >= 1) { interest /= 100; } var ratePerCompound = interest / compounded;
var periods = frequency * years; var compoundPeriods = compounded * years; var compoundsPerPeriod = compoundPeriods / periods;
var earnedInterest = 0; var balance = startVal; var compoundsDone = 0;
for(var i = 0; i < periods; i++) { var compoundsToDo = Math.floor(i * compoundsPerPeriod) - compoundsDone; for(var j = 0; j < compoundsToDo; j++) { var thisInterest = (balance * ratePerCompound); balance += thisInterest; earnedInterest += thisInterest; compoundsDone++; } balance += addVal; } form.endBalance.value = formatDollars(balance); form.depositTotal.value = formatDollars(periods * addVal); form.interestTotal.value = formatDollars(earnedInterest); } function formatDollars(num) { num = num.toString().replace(/\$|\,/g,''); if(isNaN(num)) { num = "0"; } sign = (num == (num = Math.abs(num))); num = Math.floor(num*100+0.50000000001); cents = num%100; num = Math.floor(num/100).toString(); if(cents<10) { cents = "0" + cents; } for (var i = 0; i < Math.floor((num.length-(1+i))/3); i++) { num = num.substring(0,num.length-(4*i+3))+',' + num.substring(num.length-(4*i+3)); } return (((sign)?'':'-') + '$' + num + '.' + cents); }

i just had to figure this out for my (mandatory!!!) retirement account for the state. they have a good interest rate and even though i’m not even vested yet (it’d be at 140%, so it really stinks that i don’t get any of that action) i’ll have almost 22k if i don’t take it out til i’m 65. that’s with only 1700 as my initial amount. pretty sweet i think. but the bad part is i get penalized like 35% if i want any of MY! OWN! MONEY! from the account before i’m 59. compound interest is so great.
Those are some nice gains… but it might be better to look into a Roth IRA. Where you pay taxes on your money before you put it in, that way you’ll save some money when you end up in a higher tax bracket later on down the road.
pay taxes before you put it in? like the income tax i’m already paying? or something else?
With a normal IRA the money you put in is taken out of your paycheck before taxes are taken out, with a Roth IRA taxes are taken out of your check, then the money for your IRA. Make sense?
