Another help for your mortgage calculator

Use the Microsft Excel function PPMT and IPMT to calculate the amount of principal and interest you pay back for a certain month.

Cell Content
C2 Years
C3 30
D2 Rate
D3 0.05
E2 Amount
E3 100000
H3 1


Cell I3 =PPMT($D$3/12;$H3;$C$3*12;$E$3;0)
result of cell I3 = -$120.15
Cell I4 =PPMT($D$3/12;$H4;$C$3*12;$E$3;0)
result of cell I4 = -$120.656

Cell J3 =IPMT($D$3/12;$H3;$C$3*12;$E$3;0)
Result of cell J3 = -$416.67
Cell J4 =IPMT($D$3/12;$H4;$C$3*12;$E$3;0)
Result of cell J4 = -$416.17

Cell K3 = +I3+J3
Result of cell K3 = -536,82

Cell K4 = +I4+J4
Result of cell K4 = -536,82

Here are a few more results:

excel is definitely a great tool for financial decision-making...especially if/then scenarios by changing the variables (interest rate, loan amount, term, etc.) to see how it affects the payment. if you just need a simple mortage calculator though, search for "mortgage calculator" you should find a bunch....and if you ever need advance cash on line check out the site
