The power of a spreadsheet. The feel of a modern app.

Haven is a data-sovereignty-focused digital modeling tool for your household finances. It lives in the gap between complexity and clarity — offering the power and control of a spreadsheet with the intuitive experience of a modern app.

Haven helps you methodically think about how your income is distributed between your assets, expenses, and liabilities. This relationship is what unlocks our ability to truly understand how our money is spent — and helps frame what's actually important to us.

Haven keeps your data in your hands. Zero data is collected — not even anonymous user analytics.

Income is the engine. Every dollar that flows in — from a salary, a side business, rental income, or investments — is the raw material of financial progress. But income alone is not wealth; it's potential.

Expenses determine how much of that potential you keep. Fixed obligations like housing, transportation, and debt payments compete with discretionary spending every month. The gap between what you earn and what you spend — your net cash flow — is what either builds your future or slowly erodes it.

Assets are what you build. Savings accounts, investment portfolios, real estate, and retirement funds accumulate over time and, eventually, begin generating returns of their own. The transition from depending on your income to depending on your assets is the heart of Financial Independence.

Liabilities are the counterweight. Mortgages, auto loans, and other debts reduce your net worth and redirect cash flow away from wealth-building. Paying them down accelerates your trajectory — each liability eliminated frees up monthly cash flow that compounds forward.

Net Worth view

Net Worth

Net Worth leads the view, displaying your total assets minus total liabilities alongside your Liquid Net Worth — savings and investments only, explicitly excluding real estate — so you can distinguish paper wealth from the capital readily accessible to you.

Cash Burn Rate view

Cash Burn Rate

The Cash Burn Rate section answers a critical question honestly: if your spending stayed exactly as it is today, how long would your savings last? When cash flow is positive, it shows your savings are growing. When it's negative, it calculates a runway — the amount of time before savings reach zero.

Income Loss Scenarios view

Income Loss Scenarios

Income Loss Scenarios model what happens to your household if any single member loses their income. For each person in your household, it calculates how the cash flow shift would affect your runway, giving you a concrete sense of financial resilience and risk.

Planner

Your path to Financial Independence
FI Trajectory chart

FI Trajectory

The Planner is built around a single question: when will your assets sustain your lifestyle without earned income? At the top, the FI Trajectory chart models your path to Financial Independence using your current savings rate, investment returns, and a configurable safe withdrawal rate. It shows not just a projected date, but the curve of accumulation that gets you there.

Below the chart, two tabs let you plan the spending decisions that will shape that trajectory.

Planned Goals view

Planned Goals

Planned Goals is where you map out future purchases and life events — a home renovation, a new vehicle, a major trip. Each goal shows how much you need, how far current savings and available assets can fund it, and — critically — how many months it would push back your projected FI date if you choose to act on it now. You can toggle a goal's influence on and off to compare scenarios before committing.

Replacements FI influence view

Replacements

The less glamorous but equally important half of long-term planning. Appliances fail. Roofs age. Tools wear out. The Replacements section lets you track items with a known lifespan and replacement cost, calculate a monthly set-aside that prepares you for each one, and optionally roll that set-aside into your tracked expenses. Like Planned Goals, each replacement shows its impact on your FI timeline — because even maintenance costs have a long-run cost if unplanned.
