High-interest debt comes first because paying it off is a guaranteed return equal to the interest rate you were being charged. If a card was costing you roughly 25% a year, wiping it out with the windfall is like earning 25% on that money with zero risk.
The emergency buffer comes second because one surprise — a car repair, a medical bill — shouldn't send you right back into the debt cycle. Three months of essential expenses is a solid cushion for most households.
Most of the rest goes to investing because money you don't need for years should have time to grow. A little is set aside for guilt-free fun because a plan you enjoy is a plan you stick with — spending some on purpose beats blowing it on nothing in particular.
Method
Priority waterfall
The windfall fills each bucket in order: (1) high-interest debt payoff, up to the full balance; (2) emergency buffer top-up, up to three months of your essential expenses; (3) whatever remains is split between investing and fun money.
The 90/10 split
After debt and the buffer are covered, 90% of the remainder is earmarked for investing and 10% for guilt-free fun spending. Amounts are rounded to whole dollars.
What is excluded
Taxes on the windfall
Cash bonuses are typically withheld before they reach you; inheritances and gifts vary widely by state and situation. This planner uses the amount you enter as-is.
Employer 401(k) match and investment picks
Matching contributions, asset allocation, and specific investments are outside this planner — the investing bucket is a dollar amount, not advice on what to buy.
