I am building tools to make informed financial decisions. This payoff calculator helps you figure out whether it makes more sense to pay down mortgage, student loans, credit card or other types of debt versus investing in stocks, 401K or real estate. It analyzes your specific financial situation and helps you compare these scenarios with real numbers rather than guesswork.

Thanks you, this is constructive feedback. I am making a more comprehensive version of the FIRE calculator and we will use taxable investments first, then retirement funds. You suggestion on letting user enter a monthly number is also sound.
