The Moment
You just got a 10% promotion raise. On a $75,000 salary, that is $7,500/year — roughly $480/month after taxes.
This is the raise that changes trajectories. A 3% raise maintains your position. A 5% raise is incremental progress. A 10% raise, if captured, can compress years of saving into months. If wasted on lifestyle inflation, it becomes the raise you never felt.
The 70/30 Framework
At 10%, the stakes are high enough to be more aggressive than 50/50.
70% to wealth-building (~$335/month after tax): - Max your 401(k) match if you have not already - Increase 401(k) contribution by 5-7% of salary - Open or fund a Roth IRA ($7,000/year = $583/month) - If debt exists, accelerate payoff aggressively
30% to intentional upgrades (~$145/month after tax): - Choose one to two upgrades that genuinely improve your daily experience - A better apartment, healthier food, a cleaning service, a hobby you have been deferring - Avoid diffuse spending (the $5 here, $10 there that accumulates invisibly)
The critical move: make the 70% allocation before your first increased paycheck. Call HR, adjust your 401(k), set up the auto-transfer. If you wait until you "get used to" the new income, the money is already spent.

10% Promotion Raise Allocator
The Promotion Tax Trap
A 10% raise may push you into a higher marginal tax bracket. This is not a reason to avoid the raise — marginal brackets only apply to the dollars above the threshold. But it does mean your after-tax increase is smaller than you expect.
If the raise pushes you from the 22% to the 24% bracket, the additional dollars above the threshold are taxed at 24%, not 22%. Your effective take-home increase is closer to 7.5% than 10%. Plan your allocation based on the after-tax number, not the headline percentage.

Frequently Asked Questions
Should I save 100% of a 10% raise?
You can, and for aggressive savers pursuing FIRE (financial independence), this is the right move. But for most people, the 70/30 split is sustainable long-term. The 30% lifestyle allowance prevents the resentment that causes people to abandon their savings plan entirely.
I just got promoted — should I upgrade my car or apartment?
Choose one, not both. A promotion raise disappears fastest when it funds multiple lifestyle upgrades simultaneously. If housing genuinely improves your quality of life (shorter commute, better neighborhood), prioritize that. Cars depreciate and add insurance and maintenance costs.
