When income rises, divide the increase equally between present and future consumption. Save or invest half of each raise, bonus, or other positive shock, and allow yourself to spend the other half. Maggiulli says his simulations converge near 50% for people with common lower savings rates, preserving a consistent long-term consumption path while still permitting lifestyle improvement. The split also reduces the psychological pain of saving because it redirects money the person did not previously receive. The rule assumes the current financial baseline already feels decent; someone struggling to reach an acceptable life may reasonably want to spend more of the first increase.
Origin
Nick Maggiulli says simulations in his book found that the sustainable share of raises to save converges to roughly 50%, which also mirrors his 2x Rule.
Core principles
- 01Positive income shocks can improve life now and preserve future consumption
- 02Saving half of new income limits lifestyle creep
- 03Money not previously received is psychologically easier to redirect
- 04The rule works best from an already acceptable financial baseline
How to run it
- 1
Check the baseline
Assess whether your current life and saving arrangement already feel reasonably stable. Apply the split once the baseline is acceptable.
Pro tip Separate genuine unmet needs from comparison-driven wants.
Watch out The rule is difficult to follow when current spending supports a life you consider subpar.
- 2
Capture the increase
Measure the net raise, bonus, commission increase, or other positive income shock rather than total income.
Pro tip For irregular income, apply the split whenever a larger chunk arrives.
Watch out Do not accidentally apply the percentage to gross income when only a smaller net amount is available.
- 3
Fund future you
Move half of the increase into saving or investments before the entire amount becomes part of routine spending.
Pro tip Automate the increased contribution when the income change is recurring.
Watch out Delaying the transfer makes the new income easier to absorb into lifestyle costs.
- 4
Enjoy the other half
Use the remaining half to improve current life while keeping the split intact.
Pro tip Treat the spending half as permission to benefit from progress now.
Watch out Do not let recurring commitments consume the saved half as well.
- 5
Repeat after every shock
Apply the same split to later raises and bonuses so saving capacity and lifestyle rise together.
Pro tip Review the rule when the financial baseline materially changes.
In the wild
A worker already saves 20% of income and receives a raise. Instead of saving half of total pay, they save half of the raise and spend the other half, allowing current consumption and future resources to improve together.
→ The raise improves life without putting the long-term plan off track.
A self-employed person receives a larger-than-normal payment. They treat it as a positive shock, immediately invest half, and keep half available for present spending rather than waiting for a formal salary increase.
→ The rule works even when income changes arrive as uneven chunks.
Common mistakes
Applying it before life is stable
Maggiulli says saving half is hard when someone feels their current life is below the level they want.
Saving half of total income
The rule applies to raises and bonuses, not necessarily to half of the person's entire income.
Is it for you?
Best for
It is best for people in a stable financial position who receive raises, bonuses, commissions, or irregular increases in income.
Not ideal for
It is not ideal for someone whose current spending cannot yet support an acceptable basic life.
