Simple Savings Automation

decide once, on payday

Saving whatever is left at the end of the month asks you to choose saving again every month, at the moment money is tightest. Automating it turns that into one decision: a fixed amount moves to its own pot the day you're paid, before there's a chance to spend it. Set-up choices like this one tend to stay exactly as they were set, so the one thing to get right is the amount.

the same plan, set up two ways
New hires saving in a company retirement plan, before and after it enrolled them by default Two grids of 100 people each, three to fifteen months into the job. Hired when they had to sign up themselves: 37 in 100 were saving. Hired when they were enrolled unless they said no: 86 in 100 were saving. NEW HIRES SAVING IN THE PLAN · 3–15 MONTHS IN Had to sign up themselves 37 in 100 Enrolled unless they said no 86 in 100 saving in the plan not saving each grid: 100 people

Madrian & Shea (2001): one large US company began enrolling new hires by default in April 1998, at 3% of pay. Nothing else about the plan changed.

The method

One transfer, set once, dated for payday.

  1. Open one pot and name it

    A separate savings account or a pot inside your bank app, named for what it's for: “Boiler fund”, “Rainy day”. A named pot is harder to raid than a general one.

  2. Pick the amount on purpose

    Whatever you set is likely to stay that way for months, so choose it rather than grab a round number. Make it small enough that you'd never cancel it, and no smaller.

  3. Date it for payday

    The day your pay lands, or the day after it clears. Not the end of the month: by then the money has found other jobs.

  4. Set it up once

    A standing order or recurring transfer in your bank app. From then on, saving happens unless you stop it, rather than only when you remember.

  5. Check the first one went

    Put a note in your calendar for the day after the first transfer. If it went, leave it alone. If it bounced, move the date, not the habit.

    Name a pot, pick the amount, date it for payday, set it once, check once.

Example: Ama is paid £1,950 on the 28th, and most months nothing is left to save by the 20th. They open a pot called “Boiler fund” and set a standing order of £100 for the 29th, the day after pay clears. That's £1,200 a year, and they never decide it again.

The payday planner

Plan the transfer, then set it up.

1 · The pot

2 · The amount

3 · The date

If the day falls on a weekend or holiday, most banks send it the next working day.

The research behind it

What you set up is what you keep.

In April 1998 a large US company changed one thing about its retirement plan. Before, a new hire had to fill in a form to start saving. After, new hires were enrolled automatically at 3% of pay, in the plan's money market fund, unless they said no. The match, the funds and the rules all stayed the same.

Brigitte Madrian and Dennis Shea compared the people hired just before the change with those hired just after, at the same point in their jobs. Of those who had to sign up, 37% were saving. Of those enrolled unless they said no, 86% were. Nobody had to save, and anyone could leave at any time. Most simply never got round to changing what had been set up for them.

Share of new hires who kept exactly what was set up for them: 61% of those hired under automatic enrollment were at 3% in the money market fund, against 1% of earlier hires who chose that for themselves. AT EXACTLY 3%, ALL IN THE MONEY MARKET FUND Hired after the change enrolled at that setting unless they said no 61% Hired before it chose it themselves 1% 0% 25% 50% 75% 100%
Madrian & Shea (2001). The setting the company picked became the most common choice by far, though almost nobody had picked it before.

The same stickiness cut the other way. Before the change, the most popular choice among new savers was 6%, the most the company would match once they qualified. Afterwards, many people who would have chosen 6% stayed at the 3% they'd been handed, and the average rate among those saving fell from 7.4% to 4.4%.

So an automatic transfer is powerful because it stays put, and that cuts both ways. It keeps the saving going without a decision, and it keeps the amount wherever you first set it. That's why the method asks you to pick the amount on purpose. The step from an employer's plan to a transfer you set yourself is our own; the study looked at the plan.

Average contribution rate among new hires who were saving: 7.4% for those who signed up themselves, 4.4% for those enrolled automatically at 3%. AVERAGE SHARE OF PAY SAVED, AMONG THOSE SAVING Signed up themselves 7.4% Enrolled at 3% unless they said no 4.4% the 3% setting 0% 2% 4% 6% 8% 10%
Madrian & Shea (2001), new hires 3–15 months into the job. More people saved under the default, but those who would have saved anyway often saved less.

The idea

Why it works.

Saving from what's left needs a good decision every month, made when the account is lowest and the reasons to spend are loudest. An automatic transfer needs one decision, made once, on a calm day. After that, doing nothing means saving.

Dating it for payday matters as much as automating it. On payday the money hasn't been spent yet, so moving it out costs less than at any other point in the month.

When it goes wrong

Habits that help.

  • Small beats cancelled. A transfer you stop in month three saves less than a smaller one that runs all year. Start where you're sure, and raise it later.
  • Don't let the first number be the last. It will stay put unless you move it. Diary a look at it after your next pay rise.
  • Keep it out of sight. A pot you see every time you check your balance is easy to dip into. A separate account is harder.
  • If it bounces, move the date. A failed transfer usually means the date is wrong, not the plan. Shift it to the day after pay clears.
