HI guys,

I was wondering if any of you have found this compound interest calculator site helpful:

http://www.thecalculatorsite.com/finance/calculators/compoundinterestcalculator.phpI tested it out and I'm not sure what to think of it. It looks like a lot of good news but perhaps its off. Maybe even way way off. I was wondering if another mustachian could test it out, maybe even based on old retirement statements, to see how this fairs.

Work out the compound interest on your savings with these popular calculators. Use the first calculator to include regular monthly deposits or withdrawals (for retirement calculations, etc). Use the second calculator to work out interest on a simple lump sum savings amount. In our article archive, you can learn about compound interest or read our article explaining the formula for compound interest.
