Vibes Investor

Simplify wealth creation with an investing engine that compounds gains instead of fees.

Design your wealth engine

Invest a small percentage of what you earn each month. Over time it compounds into something incredible.

Every number on this page is arithmetic on these. Change any of them and judge the result yourself; that is the point of a tool.

Lower costs. Higher returns

Keep fees low. You pay them win or lose, and they eat your gains like a parasite.

Index funds charge 0.02% to 0.10%.
Managed funds charge 0.5% to 1.5%; add an advisor and it is 2% or more.

More time. More compound growth

The sooner you start, the sooner compounding growth kicks in.

US accounts only

Fill the right tanks first US only

The fund is the engine; the account is the garage. The same fund is taxed differently in each, so the order matters. This part is US rules and 2026 limits only; other countries have their own equivalents (ISA, TFSA, superannuation). Not tax advice.

2026: $24,500 · +$8,000 at 50 · +$11,250 at 60–63

Your workplace plan. Take the full match first: it is free money. Then pick the index fund on the menu.

IRA

2026: $7,500 a year · $8,600 from age 50

Your own retirement account, any broker, any fund. Roth: tax now, never again. Traditional: tax later. Most beginners start with a Roth.

HSA

2026: $4,400 self · $8,750 family · +$1,000 at 55 · needs a high-deductible health plan

Never taxed: going in, growing, or coming out for medical costs. Invest it and let it compound; after 65 it works like an IRA.

Taxable brokerage

No limit · dividends and gains taxed yearly · long-term gains taxed at 0–20%

For everything else, and the one you can spend any time. Hold broad index ETFs here; keep bonds in the tax-sheltered tanks.

On fees

The Tyranny of Compounding Costs · Jack Bogle, via PBS Frontline

A 2% fee over a working life hands about two-thirds of your money to the fund company. Sharpe's two-page Arithmetic of Active Management proves why: after costs, passive must win.

The evidence

Fund fees predict future success or failure · Morningstar

Fees predict fund results better than star ratings or past performance: the cheapest fifth of funds succeeded 62% of the time, the priciest fifth 20%.

On time

The Freakishly Strong Base · Morgan Housel

About 97% of Buffett's fortune arrived after age 50. Time in the market beat brilliance.

Six ways

Berkshire Hathaway 2017 shareholder letter · Warren Buffett

Buffett's bet: the index fund made 8.5% a year, the hedge funds 0.3% to 6.5%. Self-directed traders trail the market (Barber and Odean), and a few big winners carry the whole market, so random picks fare badly (Bessembinder).

Staying ahead

SPIVA U.S. Scorecard and Persistence Scorecard · S&P Dow Jones Indices

84% of active funds trailed the S&P 500 over ten years, 92% over twenty. Of the top funds in 2021, none were still on top in 2025 (Fama and French: luck, not skill).

How the math works. Each month the balance grows by (return − fees), then your contribution is added. Taxes and market swings are left out on purpose: they change the numbers, not the shape.
