Your loan already names the age you will be at the last payment. Pick a better age. The page finds the smallest extra amount each month, or the one payment today, that gets you there.
Each bar is the extra amount a month for one age, from the same full search. A younger age needs a longer bar. Pick one to make it your goal.
The amounts are on top of what you pay now. The second line is the one payment today that does the same, and the interest it keeps.
One honest note: paying off the loan ends principal and interest only. Property taxes and insurance never stop. Budget for both, even mortgage-free.
Step 3
Decide once. Your mortgage company sends the extra each month, and a yearly reminder keeps the plan honest.
The link holds your loan, your birth date and your age, so a bookmark keeps them. The reminder is a calendar file your device makes; nothing is sent.
Each year of the plan, and the cent that decides the birthday.

A date on a schedule means little. An age means a lot. Three reasons the birthday is worth a price.
Dollar figures use the example: a $400,000 loan at 6.5% over 30 years, first payment Aug 2026, borrower born June 1985: 41 at signing, 71 at the scheduled last payment. Run your own numbers above.
Retire with this mortgage and your savings must produce $30,339 a year before a single grocery. That is the $2,528.27 payment, twelve times a year, from a fixed income. At a 4% withdrawal rate it takes about $758,481 of portfolio to fund. Kill the payment first and you need none of it. A paid-off house does the work of three-quarters of a million dollars in savings. That is the prize this page is pricing.
On the example loan, paid-off-by-67 costs $134.69 a month extra. By 65 it’s $221.89. By 60, $538.00. By 55, $1,117.48. The price roughly doubles every five birthdays you move the flag. Fewer payments must carry the same principal. Waiting works the same way in reverse: every year you delay raises the price of your age. The cheapest plan is the one that starts this month.
A bad market just before or after retirement does permanent damage. Selling investments in a downturn to pay fixed bills is how portfolios die early. A paid-off mortgage is immune. Its 6.5% was locked the day you prepaid, and the bill it deletes never comes back. Could the same dollars earn more invested? Maybe; prepay vs invest prices that honestly. But a paid-off house has one power no fund can match: it cannot have a bad year.
Each answer below uses your loan and what you pay now. Open a tool to change the rest; your numbers carry over.
Before retirementYou are here
When does the loan end now?
Try any extra amount, one-time payments or bi-weekly, and watch the date move.
Open the payoff calculatorSee every payment?
Every payment, split into interest and principal, with the rows an extra amount deletes.
Open the scheduleDebt-free in 20 years?
Or pay $61,225 once, today. Any other month works too.
Pick a dateInvest the $200 instead?
Assumes 7% a year after tax, to Jul 2056. Paying extra earns a guaranteed 6.5%; the 7% is not guaranteed.
Race the two roadsPay half every 2 weeks?
The loan ends 5 yrs 10 mos sooner. 26 half payments a year equal 13 full payments.
Run the true calendarRecast after a $50,000 payment?
The new payment is $2,208.67. Keep paying $2,528.27 instead and the loan ends in May 2048.
See both roadsRefinance at 5.5%?
The usual formula says 25. This line uses an example offer: 5.5% and $6,000 in costs, rolled in, a year from now.
Price an offerPay off the loan a year from now?
Your statement would show $395,529.10. The payoff adds 14 days of interest at $70.44 a day.
Price the payoffWhen can PMI stop?
Without a request it stops at payment #102. This line uses an example home value of $450,000.
Find both datesThe strongest argument is cash flow, not interest. A retirement budget with no mortgage payment needs less income. Less income means a smaller portfolio and smaller withdrawals, right when bad market years hurt most. The counterweights are real: money locked in the house, and a rate the market may beat. So price both sides. This page prices the payoff; the prepay-vs-invest calculator prices the alternative. Just don’t drift into retirement with the payment by default, unpriced.
Because “Jul 2056” means little and “you’ll be 71” means a lot. People under-plan for a future self who feels like a stranger. Ages fix that; dates don’t. The math is the same as the debt-free-by-date calculator. “By 65” means paid off by your 65th-birthday month, computed from your birth month, so the deadline is exact.
Before 59½, almost never. An early withdrawal usually pays a 10% penalty plus ordinary income tax. Wiping a 6.5% loan can cost 30 to 40% up front. No rate justifies that. After 59½ the penalty is gone but the tax is not, and one big withdrawal can push you into a higher bracket. That is why this calculator solves for a monthly amount from income. It reaches the same birthday without cracking the nest egg.
Aim later and keep the habit. The table above prices every birthday, and each one you beat deletes years of payments from your retirement budget. Two levers help at the edge: a recast at retirement can turn a lump sum into a permanently smaller payment, and every dollar you prepaid makes that payment smaller still. Partial progress is not a consolation prize. It is the same interest math, prorated.
Yes, to the cent, for the loan as entered. It is the smallest monthly extra that reaches zero balance by your birthday month. The page proves it live: it re-runs the schedule at one cent less and shows you the month it misses. If you already pay extra or brought cash, the answer is what you need on top.
No, and retirement plans go wrong on exactly this point. Paying off the loan ends principal and interest: $2,528.27 a month on the example loan. Property taxes and insurance continue as long as you own the home, and they tend to rise. This calculator is principal and interest only, like every tool on this site. Budget the escrow items separately, forever.
