Letâs look at a hypothetical spontaneous chemical reaction: The quantity of usable energy (chemical potential) in a reaction is called the Gibbs Free Energy (DG). DG is the difference between the energy contained in the products of a reaction and the reactants: DG = (energy of products) - (energy of reactants)
That's why some financial experts feel it's more realistic to think in terms of your net income, aka take-home pay, and that you shouldn't use any more than 25% of your take-home on your mortgage payment.
If you pay a standard monthly payment of $272 a month, you will ultimately pay $32,585 on your loans. If you pay on a graduated plan, starting with $152 a month and increasing to $455 a month over time, youâll ultimately pay $33,979 on your loans. If you pay on a lower âpay as you earn plan,â starting with $104 a month and increasing to $272 a month, you will ultimately pay $39,509 on your loans. 2 Start with the standard repayment plan if you can afford it.
