Mortgage and Financial Calculators

 

  • Blended Rate Calculator - Calculate the effective rate of multiple loans.
  • Investment/Savings Comparison This allows you to compare a variety of investment options with two side by side saving/investments cases you can modify.
  • How much house can you afford? - This has been changed to allow higher debt ratios for expensive housing markets.
  • Estate Tax Calculator - Estimate your total taxable estate and how much estate tax you would pay! Updated to reflect new tax "cut" bill. The estate tax is now a very funny little creature indeed. Die before 2011 or you lose!
  • Minimum IRA Distribution Comparison - I changed this to follow new IRS laws that require your IRA custodian (brokerage, fund family etc) to withdraw a specific minimum as specified by IRS law. This makes this whole "minimum withdrawal" effort much less complicated.
  • Save a fortune by not smoking, Similar to my "lunch" calculator this lets you see how you can buy a nice vacation or even a new car if you stop smoking cigarettes every day. A suggestion from RF of Richmond, VA.
  • Wealth Percentile Score - I did some interpolation so you can compare how your net worth stacks up to everybody else's in your age range.
  • Generic Loan Amortization - It seems people want to see weekly, daily, quarterly, you name it amortizations. Okay, I will make a generic loan amortization where you specify the number of periods per year.
  • Penalty-free IRA withdrawals before 59 1/2 - Did you realize there is a special IRS rule that let's you make regular withdrawals before 59 1/2 without paying the 10% penalty? You must make "substantially equal" withdrawals over a minimum 5 year period. Look here for more information.
  • Lunch Savings Calculator - It's amazing to see people who go out to eat lunch everyday, spending $3 to $6 for five days a week to eat. I wonder what would happen if calculated the savings over making your own $1 lunch every day...
  • CPI/Inflation Muliplier Remember back when you could buy a car in 1972 for $2,500? Has inflation inflation really made that car cost $20,000 now? Well, I grabbed the U.S. CPI (consumer price index) information from the Labor Bureau for 1913-1999 to see how inflation has really increased. Neat stuff.
  • JavaScript Amortization Spreadsheet Here is a spreadsheet all written in JavaScript that calculates the nitty gritty of your amortization and lets you change any variable anywhere (rate, payment, etc) This is good to track non-uniform principal prepayments, and also ARM's where rates change. Note that this is for 60 months (5 years) only. I am still playing with a Yearly pl. For some reason it won't run on the MMIS server, but I'm working on it.
  • Minimum IRA withdrawal calculator How come so many places talk about the 70 1/2 withdrawal requirements but don't show you the numbers? The reason is because it is complicated! Here are the minimum withdrawal requirements for a single life (i.e. no beneficiaries) IRA. Note that even though you must withdraw the amounts from your IRA (or suffer a penalty) and pay tax on the distributions, you don't have to spend it!
  • What's Missing? Loan Calculator This simple program finds the missing loan variable (loan amount, monthly payment, interest rate or number of months).
  • Rule of 78 Loan Calculator A few people have asked me about this one, so I researched it out and wrote it up. Boy, these loans are weird!
  • What's a Million? Let's see how long it takes to reach a financial goal, say a million dollars, but then let's see how much that will be worth then!.
  • Compound It! This simple JavaScript does a monthly compounding on a fixed balance as well as contributions.
  • Calculate your AMT Tax (Alternative Minimum Tax!). With too many exemptions you may have to recalculate your income tax!
  • Here's a simple little JavaScript calculator that shows you the after tax interest rate of your mortgage. It also shows the after-tax return on your investment income. Taxes do weird things to rates!
  • E-Mail amortization Forms -- Straight Amortization or Prepayment
    Some people complain that their browsers crash when pulling down an amortization schedule. Well, now I will e-mail you one! You can either use a full schedule without any prepayment, or start with your current loan amount and enter any monthly payment amount you want. Having it as e-mail makes an easier permanent record for printing, importing or just to fill up your mailbox!
  • Roth IRA Conversion Calculator - My version, and I don't even sell my own mutual funds!
  • Retirement Payout Calculator - a modification of "duration.pl" to show the fixed payout out of an annuity in a perfect world.
  • Wealth Calculator This uses the formulas and discussion from Stanley and Danko's best-seller The Millionaire Next Door so you can see how wealthy you really are.
  • Updated IRA/401K/403B Calculator This takes old annuity calculator and adds the under 59 1/2 penalties and the minimum withdrawal requirements. Note that this follows current "standard" IRA laws, whereas the new "Roth" IRA's will actually follow older calculator. And remember when you take withdrawals from your Roth IRA's you PAY NO TAX! They are really too good to believe. I hope you rolled over your present IRA's in 1998 while you could get the special 4 year deal too!
  • JavaScript Mortgage Payment Calculator Here is a simple JavaScript example for an interactive calculator. It just takes a few inputs and figures out your monthly payment. Like all JavaScript, the source is embedded in the HTML. (Requires a JavaScript capable browser.)
  • What's Your Yield? Find the long term yield of your investments given start and ending amounts and how much you contribute each month.
  • Income Qualification Calculator - I calculated the numbers right but explained them out wrong! I don't want people to think they can buy more than they can really qualify for!

  • APR Calculator #2 - Find the APR of a loan given points, and other included costs.
  • Simple Savings Calculator - Given a beginning balance and a monthly deposit, watch you money grow!
  • Tuition Savings Calculator - As a full-time university employee, one great benefit is free tuition for my kids! It's frightening to think how much it would cost otherwise.
  • Simple Loan Calculator - Only three inputs, loan amount, interest and length of loan, calculates the monthly payment for any type of fixed payment, fixed period amortized loan (mortgage, car loan, etc).
  • Canadian mortgage payment calculator - Now both calculates loan amount or monthly payment
  • FHA vs. Conventional 95 LTV loan calculator - This shows two very popular plans for first time buyers and how much house you can afford with your cash and income levels.
  • Retirement Calculator - Enter required income, number of years, and inflation and this will tell you how much you must put away.
