Here is a brief caption of each tab and calculator within the above link. You can also link to the individual calculators below by clicking on the bold underline type

Loan Payment: This offers a simple payment calculation for a fully amortized, plain vanilla loan. 
Housing Payment: This calculates your total payment, including tax, insurance, HOA dues, etc.
Pre-payment Analysis: If you want to pay off your mortgage faster than the full term of the loan, this is a very valuable tool.

Simple refi: This will help you determine whether or not to refinance. It calculates payment savings for you.
Refi comparison: This helps you determine the wisdom of a refinance among 3 options.
Fixed vs. ARM: Choosing an adjustable rate mortgage carries more risk than a fixed rate mortgage. This calculator helps you determine if the reward is worth the risk.

Pre-approval: this tab helps you determine if you qualify for a conventional mortgage. In truth, there are many different debt-to-income ratios allowed by various lenders and loan programs. This calculator uses 40%, but that is not the final word. So if the calculator says you don't qualify, don't give up. Please call me.
Quick qualify: This helps you determine if you have enough cash in the bank and income to qualify for the home you want.

The Total Cost and Benefits Calculator is a very valuable tool if you are deciding whether to put your money into real estate, or into other investments. I created a much more detailed calculator in Excel. If you or your financial planner would like the more detailed version, I can email it to you.

The True Percentage Rate corrects for the notoriously inaccurate APR. You may be choosing the wrong loan if you rely on APR quotes. This helps you compare loans more easily than the lender's quoted APR.

Seller buy down: you may save more money over time buying down your rate with seller concessions. This simple calculator helps you see the wisdom of that choice.
 Linear Value (both 15 and 20): both of these demonstrate the likely value of your property in the future.
15 vs. 30 Year Loan: This helps you compare a 15 year fixed loan to a 30 year fixed loan.

The Financial Calculator helps you know what to do to reach your savings goals, and determine how long it may take you to reach the goal.
