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.
Calculate how long it will take to pay off your home loan. Planning how long itâll take you to pay a mortgage off is a crucial step when comparing home loans. The minimum monthly payment for your mortgage is calculated on how much is needed to pay off the balance of the loan over the loan term, plus the interest that has been accrued. The average loan term is approximately 25 years. There are shorter terms available but it could mean that your minimum monthly repayment is higher. Even if you can pay out your loan in 10 or 15 years, it may still be worthwhile to get a loan term of 25 years. This will give you more flexibility and could be useful in emergencies. It also means that your minimum monthly payment wonât be as high.
