How to read the schedule
The interesting month is the one where principal overtakes interest. On a thirty-year loan at current pricing that arrives in year seventeen, which is why a fifteen or twenty year term changes the arithmetic so dramatically.
Ask an originatorBecause interest accrues on the outstanding balance, and in month one the balance is at its largest. On a $320,000 loan at 6.125%, the first payment of $1,944 is $1,633 interest and $311 principal. The split crosses over at roughly month 205 on a thirty-year term.
Principal, interest, taxes and insurance. It leaves out association dues, mortgage insurance, utilities and maintenance. On a Center City condominium the dues alone can be $400 a month, which is why our affordability tool asks for them separately.
On that same $320,000 loan, one additional monthly payment each year retires the loan roughly five years early and saves about $84,000 in interest. Enter the equivalent monthly figure in the extra principal field on the PMI timeline tool to see it.
That is the current Philadelphia County rate applied to assessed value (sample figure). Montgomery and Chester counties run lower, Camden County in New Jersey runs far higher at about 2.68% effective. Always enter the figure for the actual property.
