Overcoming Saving Inertia with Future Commitments

Average Retirement Saving Rate moved from 3.5% to 13.6% — a +10.1 percentage-point (289% relative) change (sample: 3 companies, 1,200 employees).

Study details

Challenge
Employees consistently failed to save enough for retirement, even when offered matched contributions, because of immediate consumption desires (present bias) and loss aversion.
Intervention
Implemented the 'Save More Tomorrow' (SLaT) protocol: employees commit to allocating a portion of their *future* salary raises to their retirement fund, bypassing current pocket pain.
Outcome
Average Retirement Saving Rate: 3.5% (control) → 13.6% (treatment); +10.1 pts, 289% relative
Sample
3 companies, 1,200 employees
Key takeaway
Committing future (rather than current) gains to long-term welfare completely disarms loss aversion and present bias, creating sustainable compound savings.
