Mortgage Payment
This flexible calculator allows you to show a full amortization schedule after you input the Principal, Interest Rate, Term, starting month and year. It also allows you to model a variety of prepayment options, such as monthly or lump sum and summarizes the savings...

What's Missing
This calculator finds the missing variable for a loan. If you know the payment, term and the loan amount it calculates the interest rate. If you know the payment amount, loan amount and the interest rate, it calculates the term. Get the idea?

Prepay or Invest
This form allows you to compare what would happen if you took one of two choices with some extra cash you have -- prepaying your mortgage each month, or investing it instead.

Payoff or Keep
This form allows you to compare what would happen if you took one of two choices with a big chunk of cash you have -- paying off your mortgage, or investing it instead.

Prepayment 1
This form allows you to see how prepaying your mortgage reduces the length of your mortgage by putting in the current values for your loan.

Prepayment 2
This calculator takes a principal amount, interest rate, normal length of the loan, and then allows you to determine how long you’d like the loan to last (in which case it will solve for your new payment to meet that remaining term, or how much you’d like to pay (in which case it will solve for your new remaining term based on that new payment).

Mortgage Qualifying Income
The calculator will work to calculate what kind of income needed to qualify for specific values. Enter in the monthly payment, taxes, home owners insurance, other debt payments, sale price of home and expected down payment, and the calculator will give you an estimate of how much income you will probably need to qualify.

Net Cost of Borrowing
Use this to compare the real after-tax interest rate of your mortgage. Then compare your after-tax yields on taxed investments and tax protected (i.e. tax-deferred 401(k),403(b),IRA accounts or tax free Roth or Education IRA accounts).

Simple Savings
This doesn't deal with inflation, taxes or any of that complicated stuff. This is just a simple calculator that lets you start with an amount of money and make regular monthly deposits, and see how much it grows.
