The average U.S. auto loan is now 68 months long at 7.3% APR. You pay $5,900 in interest on a $25,000 car just for the privilege of waiting. Twelve months of focused saving beats that every time. Here is the math, the autopay trick, and the Plan! setup that keeps you honest.

The $25,000 math

$25,000 divided by 12 months is $2,083.34 a month, or $69 a day, or roughly 40% of a $5,200 take-home. That is aggressive. If your math does not close, extend to 18 months ($1,389/mo) or target a $18,000 certified pre-owned ($1,500/mo over 12). The point is to pick a target your budget actually supports and let time do the compounding.

A parked high-yield savings account at 4.3% adds $590 of interest over 12 months on $25k of deposits. Not huge, but it pays for insurance for the first two months.

The separate-account + autopay combo

Self-discipline loses to automation every time. Open a separate HYSA specifically for the car. Set an autopay from your checking the morning after every paycheck lands. Money you never see in checking cannot be spent on a weekend trip.

  • Two paychecks per month? $1,042 autopay on the 1st and 15th.
  • Weekly? $481 every Friday.
  • Freelance? Autopay 40% of every Stripe deposit the day after it clears.

Build the goal in Plan!

Open Plan! and create a Savings goal called "New Car" with a $25,000 target and a 12-month deadline. Plan! draws the milestone line automatically: 25% at month 3, 50% at month 6, 75% at month 9. The Forecast engine tells you whether your pace is on track or if you need to trim $140 out of Wants next month.

  1. In Plan!, tap plus and choose Savings goal type.
  2. Enter $25,000, pick a 12-month deadline, assign a blue colour and a car icon.
  3. Enable milestone notifications at 25%, 50%, 75%.
  4. Add the car goal to your lock screen widget so the bar stares back every time you check the time.
  5. Link deposits with a Siri shortcut: "Hey Siri, add $500 to New Car."
Avoiding a 68-month auto loan at 7.3% saves you $5,900 in interest. That is a one-week Iceland road trip, paid in cash.

Motivation for months 5 through 9

The middle of a goal is where motivation dies. Plan! fights this three ways. The home screen widget shows the filling bar every time you unlock your phone. Milestone notifications hit like tiny trophies at each 25% mark. The Spotify-style yearly report turns your 12-month journey into a shareable summary you will actually want to screenshot. Tape a picture of the exact car to your fridge; the dopamine is free.

Checklist

  1. Pick the exact car and price you want, including taxes and fees.
  2. Open a separate HYSA and set up autopay.
  3. Create a Savings goal in Plan! with a 12-month deadline.
  4. Turn on milestone alerts at 25%, 50%, 75%.
  5. Review the Forecast engine every month; adjust spending, not the deadline.

Twelve months from now you will drive off a lot with nothing but a title. Open Plan! and pour the first brick.
