Calculate money numbers
morgage, payment, interest, save, invest, lones, retire
compound interest, inflation, math, geometry, plot, date & time math
finanshal: morgage payment (house payment), interest, cost, time tu pae off
loan types, refinance, xtra paements=save money and time.
Compound interest: save & invest...see yer money gro
how much money yu need tu save tu retire=save + kompound gro
inflation: future value of money. How flate rate ruin the $.
Time span: date, add time & dates, werk daes, how old are yu? kalander.
Convert units...length, area, volume, mass, time, energy, power, speed, etc.
solv math problems:sort, average, mean, quadratic formula, primes, fakters
plot math funkshuns, draw geometry shapes, plot data

Kost av a lone depend on $ yu borro (balans), interest rate, & time span (yeers).
Shorter lone: yu pae a lot less interest so it kost less. 15 yr lone:
the % interest is a littel less than a 30 yr lone.
Reelter probablee will warn yu tu NOT get 15 yr lone. Her will sae
it put yu at risk if yu luze job or hav big medikal bills...yu mae hav
prob make hous paement. The wae round this is tu get 30 yr lone,
but evree month send in dollars for a 15 yr lone. Then if yu ever hav munee
probs, yu kan send in less money for a wile.
Aft 5 yrs paeing like a 15-yr lone, balans=76,308$. Yu paed off 23,692$.
Puter calculates numbers 2 waes:
1. % interest stae at the (very lo) start rate.
2. % interest go up at max rate set in lone papers.
ARM (Adjustabel Rate Morgage) has loest interest rate əv NE lone.
As əv 15 Apr 04, for 1 yeer arm (% fixed for first yeer), if yu hav the
best kredit, yu pae 3.69%. In retern, yu aksept the risk interest rate
mae go up & yer paement mae go up tu.
Program got tu big...puter kant handel it. So me kut it in 2 parts.
part 1=most opshuns
part 2=make paement skedyuel (amortizashun tabel)
The maen prob with ARMs is folk hu bi em kauz it iz the onlee wae em
kan make this months paement. Em dont thank bout the fyucher kauz em
liv hand-tu-mouth alredee. Em just hav a vaeg hope thangs will get
better sumdae. ARMs hav the loest interest rate. Its theer onlee hope.
ARMs had a lotta probs in the erlee yeers, so the Fed govt steped in
an imposed rules on the bankers. The rules sae banker gotta tell yu
bout the "terms". This meens him gotta menshun all the vareebels and
tell yu how him pute the numbers. ARMs hav a lot more vareebels than
a "standard" fixed rate lone. Sins the interest rate varee,
him gotta sae how oft, how much, how kum, & spesifi limits.
Normal...theer is a start time pereeod wen stuff is fixed...paement
& interest. Normal=6 months tu 1 yeer. Then thangs chaenj. The %
interest gotta be based on sumthang. Normal=it is based on sum tipe
av lone, yuzually on a lone INDEX. Most kommun index nowadaes is US
fed govt 1-yeer "bill". This is a govt IOU. Bankers thank unkel Sam
is good risk, so him pae the loest % in town.
The BASE is the thang (index) the banker yuz. The MARGIN is the dif
tween the base & wot banker charj yu. Next, banker gotta sae how oft
him calculate nu % interest. Norm=6 months or 1 yeer. Then theer R kaps.
Kaps R limits tu how much yu gotta pae...max size əv chaenjes (eech won
& max for the life əv the lone). Ex...step max mae be 1/2%=max him kan
up the interest rate eech time. Life time max interest mae be 10%.
If interest rate go up (99% əv the time), yu mae hafta pae more $/month.
Hier % meen yu pae more money tu interest & less tu pae off lone. If % get
tu hi, yer paement mae not kuver the interest. So banker tell yu tu
pae more $/month. Papers from banker gotta spell out the rules bout
how him duit. In sampel belo, paement dubbels from 460$ tu 853$.
Hous-poor...yu R deep in debt...on the verj əv go tu poor hous.
(nowadaes kalled homeless), bankrupt, bellee up, broke & tied in nots.
Yu stretched evreethang tu the limit tu get the max morgage yu kood...
the most spensiv hous yu kan (maby) pae for. Then kame kid 1.
At wons, yu spend 30% more but wife had tu quit her job, so inkum go
down 30%. Now yu skrape penees tu tri tu keep the banker at bae.
Yu R behind on paements, maxed out 20 kredit Kards, debts keep groing
like mad, krediters bang on yer door at nite. Kids hungree. Kid 5
weers hand-me-downs from 2, 3, & 4. Kids trash the hous faster than
yu kan kleen up behind em. Draen baked up, but yu kant afford tu kall
a plumber. The inside əv yer 13-yr old kar looks like shit kauz 6 kids
and 2 dogs luv tu bouns on the seets. kid 1 wines kauz yu wont bi him
an 80,000$ Mersaedeez (106,708.83$ with interest...yuz program 3...yer
a poor risk & gotta pae ski hi interest). Orthodontist tri tu kollekt
8000$ yu oe him for the uglee braeses on kid 3. Hit man from lone
shark thretin tu du nonnamed dismemberment tu non spesified bodee parts.
All bekauz yu HAD tu impress yer nabers. Was it werth it? Yer kall.
Calculate paement & kost for 2 similar lones (from 2 dif bankers).
This adds kloesing kosts tu lone bekaus if yu pae kosts outside the
lone, yu reduce savings that kood ern interest... the interest yu forgo
is a kost. Approx bekauz interest on savings < interest on lone.
program 10
4 numbers define a lone, need 3 tu get 1 yu want
1=% interest (interest rate)
2=$ borroed (balans=$ yu oe)
3=lone length=time span=yeers & months ("duration" in banker-speek)
4=paement ($/month, week, etc).
Yu kan save money & time if yu konvert morgage tu biweeklee.
Yu pae banker evree 2 weeks insted əv evree month. Puter calculate
how fast yu paeoff morgage & how much yu save. Kan be big buks.
Beware əv krooks hu send junk mael saeing em will duit fer yu for
onlee 179.9999$. Most bankers chaenj theer papers free. A greedee
banker mite charj 25$. Maby a fone kall will duit in 10 minutes.
Biweekly paements...Divide $/month bi 2 & send in that number
evree 2 weeks. But yu pae 26 times/yeer. So same as send in 13 monthly
paements=like 1 xtra monthly paement/yeer.
Note...make shuer banker will kredit yer akkount wen the money kum.
Yu redues balans after 2 weeks & thus pae less interest unless banker
kant handle NE chaenj tu his rigid skedyuel.
Or yu kan send in xtra money with eech paement.
Xtra 50$/month giv bout same result as biweekly pae.

Cost əv living numbers for past yeers kum from Federal Reserv Bank
at Minneapolis (numbers for 1800 intu 2011). Last 12 months data from
Buro əv Laber Stats.
Flate rate 1800 tu 2011=1.25%/yeer or 1,273% (211 yeers)
A dollar in the hand is werth 2$ 5 yeers from now (or 6 yrs, or...).
This is the time value av munee. A dollar now is alwaes werth more than
a dollar in the fyucher.
The present value əv fyucher munee is same as the value əv yer money
x yeers in fyucher with flate rate=x%...yuz output 5 tu calculate present value.
Diff wae tu look at it...present value is based on how much a streem əv munee
(inkum) is werth...see program 20 (annuity).
save money for tu retire on yer pile-o-doe.
Similiar tu IRA in that yer munee gro tax deferred til yu take out money
(assumed tu be wen yu retire). The kumpanee takes out the munee, so yu
never see it, so yer not tempted tu spend it.
401k and its kuzins hav this going fer em...
1. Em redues yer taxes evree yeer. Evree dollar yu put intu the 401k kuts
the pre-tax inkum on the form yu get from the Kumpanee at 1040 time.
2. The money gro tax deferred. This meens yu delae paeing taxes on the
ernings (interest) yer munee gets til yu take it out (wen retired).
3. Yu kan put more money intu a 401k than intu an IRA (13,000$ in 2004).
4. The kumpanee mae add xtra $s tu yer akkount (kumpanee match).
The biggest prob is...the "plan" gotta be offered bi the kumpanee yu
werk for. Onlee half əv full-time werkers in US werk for rite kumpanee.
The program assumes yu will hav a job with good pae for as long as
yu want. It assumes yu will retire wen yu want...not wen foersed tu.
In tudaes werld this is rather optamistik. In the reel werld, yu R
likely tu be laed off at aej=45 & never agin hav a reel job. Yu will
be foersed tu take NE job yu kan get & aksept wotever em pae yu. Yu
gotta liv yeers at a time wen yu dont hav NE inkum tu speek av.
Sum geeks hav a program that ask yu how fast yer fyucher kumpanee
pae will go up. This is so outraejus, it is silly. It dont hav NE
konnekt tu the reel werld...we kant even predikt IF we will hav a job
next yeer...let alone wich state the next temp job will be in.
Will yu hav nuff money tu retire? or for NE big fyucher spend?
Tell puter how much yu hav now, wot yu wanna hav. Puter calculate
$/month yu gotta save.
Yu hav a pile-av-doe saved up. Time tu retire so yu wanna liv on it.
Yu wanna no how much $/month paeout yu kan take out & hav it last n yeers.
This is similar tu bi an annuity from an inshuer kumpanee. Em will sae
how much $/month based on how much money yu put up, how old yu R, wot %
retern em spekt tu get bi investing yer munee, the paeout opshun yu
sine up fer, how much profit em wanna make, how big theer spenses R,
How much em set aside as a rezerv tu kuver possible probs, etc.
Yu kan be yer inshuer kumpanee. Avoid the hassels, take all the
profit, no kosts, & yu kan chaenj yer mind NE time yu want.
Yuniversity proffesers konsider an annuity tu be the present value əv
fyucher munee. Em sae it is the money yu gotta put up tudae tu get a stedee
streem əv money kummin in evree month. So all the fyucher money yu get is now
werth x$...how much yu gotta put up tudae.
