When the Carters bought their home in 2005, they signed a 30-year, $380,000 mortgage at 5.875%. They paid it off in March 2024 — 19 years and 1 month later, 11 years ahead of schedule. Total interest paid: $186,000. Interest saved vs. the original schedule: roughly $142,000.
What four moves made this possible?
One: from year three onward, they rounded their payment up to the nearest $100. Two: every tax refund went straight to principal. Three: they refinanced once in 2012 to drop the rate to 3.75%. Four: starting year 10, they added $500/month from a paid-off car payment.
Did they sacrifice retirement savings?
No. They kept maxing 401(k) matches throughout. Early payoff was funded from cash flow improvements (paid-off cars, raises) and windfalls.
Was paying off worth it vs. investing?
Mathematically, investing might have netted slightly more in a strong market. But the psychological win — owning the home outright in their 50s — was worth everything. Use our calculator to run your own numbers.
