Step 2 of 4

What are you aiming for?

Pick the goal that fits you — a lump sum to build, or a monthly income to live on.

To draw /month you'll need about invested by — assuming a sustainable %/yr withdrawal (the classic 4% rule).

Step 3 of 4

How will you get there?

Choose the lever you control — Meridian solves for the other.

Your drawdown budget

A deeper drawdown budget targets more return.

· S&P 500 ≈ % max drawdown in the backtest window (it fell ~-55% in 2008)

Backtested over a crypto-friendly decade — at the deepest drawdown settings the book tilts into crypto, which can fall harder than the S&P 500 in a future downturn.
