How This Calculator Works
Enter any starting balance, the after-tax monthly amount of your raise that you'll invest, the return you expect, and the years. The calculator compounds the balance monthly and shows the ending value and how much is growth. The idea: keep living on your old income and invest the difference.
The Formula
Future Value with Regular Contributions
P = starting amount, PMT = monthly contribution, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
Investing $300 a month (an after-tax raise) plus a $2,000 start for 25 years at 7% grows to about $254,472 — with roughly $162,472 of that being investment growth. The power of 'investing your raise' is that the money was never in your budget, so you don't feel its absence — you simply keep your lifestyle steady and let the increase compound. Repeat it with each future raise and the effect multiplies, building serious wealth from money you'd otherwise barely notice spending.
Key Insight
Investing your raise is one of the most effective wealth-building habits precisely because it counters lifestyle creep — the tendency for spending to rise with income, leaving people no better off despite earning more. The mechanism is behavioral and powerful: because you never adjusted your spending to the higher income, redirecting the raise to investments costs you no felt sacrifice. A few ways to apply it: automate it the moment the raise hits (route the increase straight to a 401(k), IRA, or brokerage before it reaches your checking account), use the after-tax monthly figure (a gross raise is reduced by taxes), and 'bank' a portion of every future raise so your saving rate climbs over your career while your lifestyle grows more slowly. This compounds doubly — each raise adds to the contribution and each contribution compounds over the remaining years. Caveats: it's a nominal return before inflation, markets aren't smooth, and gains in a taxable account are taxable, so tax-advantaged accounts improve the outcome. Even banking just half of each raise (enjoying the other half) dramatically improves long-term wealth while still letting your lifestyle rise. The calculator shows what a single raise becomes; the real strategy is doing it with every raise, for a saving rate that quietly grows as you earn more.
Frequently Asked Questions
How is the growth calculated?
Your starting balance and each monthly contribution (your raise's after-tax monthly amount) compound at the expected return (annual rate ÷ 12 per month). $2,000 plus $300/month for 25 years at 7% grows to about $254,472, with roughly $162,472 of that being growth.
What is 'investing your raise'?
Keeping your spending at your old income level and investing the increase from a raise rather than absorbing it into higher spending. Because the money was never in your budget, you don't feel its absence — it's a near-painless way to boost your saving rate and build wealth.
Should I use the gross or after-tax raise?
After-tax — the amount that actually reaches you. A gross raise is reduced by income and payroll taxes, so the monthly amount you can invest is less than the headline increase. (Routing it into a pre-tax 401(k) changes the tax timing, but use the realistic monthly figure you'll actually contribute.)
How do I make this stick?
Automate it the moment the raise takes effect — increase your 401(k)/IRA contribution or set up an automatic transfer to a brokerage so the money never hits your checking account. Banking it before you see it prevents the raise from quietly being absorbed into higher spending (lifestyle creep).
Do I have to invest the whole raise?
No — even banking half of each raise (and enjoying the other half) dramatically improves long-term wealth while still letting your lifestyle rise. The key is doing it consistently with every raise, so your saving rate grows over your career rather than your spending absorbing every increase.

Methodology & Review
The future value compounds a starting balance and a fixed monthly contribution (your raise's after-tax monthly amount) at the annual return, compounded monthly. It assumes deposits at month end and a constant return; it ignores taxes on gains, fees, and inflation.
