It’s long been said that “a penny saved is a penny earned.” But when you factor in income taxes, saving that penny can actually be more valuable than earning one directly. Here’s why:
How Taxes Amplify the Value of Savings
- Gross vs. Net
When you earn one penny ($0.01) in gross income, a portion goes to taxes. In a 50% marginal tax bracket, you keep only half. - Saving a Penny
When you save one penny — by not spending it — you avoid having to earn extra pennies to cover that expense in the first place.
Mathematical Insight
Let us calculate this with an simple formula
S = penny saved (net)
t = marginal tax rate (e.g. 50% → 0.50)
To net S through income, you must earn gross G such that:

So to net one penny, you must earn two pennies before tax.
Thus:
One penny saved is worth two pennies earned in a 50% tax bracket.
Small Numerical Example
Imagine you plan to buy a small gadget that costs $0.10. You have two options:
- Earn extra income
- Skip the purchase (save the $0.10)

- Earning extra requires $0.10 gross → you keep only $0.05.
- Saving by not spending gives you the full $0.10.
Thus, saving the cost of the item yields double the net benefit of earning that same amount in a 50% tax bracket.
Generalized Table

Interpretation: At a 50% rate, each penny you avoid spending is equivalent to two pennies you’d have to earn (and then pay half in taxes) to have the same net effect.
Takeaway
- “A penny saved” sidesteps the tax bite entirely.
- Especially in high tax brackets, cutting expenses often delivers more “net dollars in hand” than striving to earn extra.
Next time you’re weighing whether to hustle for a few extra cents or simply trim a small expense, remember: in a taxed world, saving truly can be twice as valuable as earning.
