Paying extra on a mortgage. How much can I save? [duplicate]
Can I pay $12,000 extra once a year or $1000 every month - which option is better? Depends when. If you mean 12K now vs 1K a month over the next 12 months, repeating this each year, now wins. If you mean saving 1K a month for 12 months then doing a lumpsum, the 1K a month wins. Basically, a sooner payment saves you more money than a later payment. The first option does sound better, but for a 30 year mortgage, is it that significant? Your number one issue is that you have a thirty year mortgage. The interest you pay on it is monstrous. For the 30 year term, you pay around 500K in interest. A 15-year mortgage is 300K cheaper (only 200K in interest will be paid). The monthly payment would be 1250 more. How much money and years on a mortgage can I save? When is the best time to pay? At the end of each year? You can knock off about a dozen years. Save I think ~250K. You can find mortgage calculators online or talk to your mortgage advisor to play around with the numbers.
