Our Purpose

Self-reliance starts with measurement.

Nobody owes you retirement. Nobody owes you security. But you deserve the tools to build both. Ledger Life shows you where you actually stand — not just your bank account, but your entire life position — so you can make decisions with your eyes open.

Your financial advisor sees your portfolio. Your doctor sees your vitals. Nobody sees how your health, earning power, relationships, and costs interact — all at once, in one place. That's what Life Capital does.

We show you the tradeoffs. We never tell you what to do. Change your spending, your career, your health habits — and watch exactly how it moves the needle. Every lever is visible. Every consequence is quantified. What you do with it is yours.

Self-reliance over entitlement
We give you the measurement. You make the decisions. Your position is yours to own — nobody else will do it for you.
Privacy by architecture
Everything runs on your device. Nothing leaves your browser without your explicit say-so.
Honest uncertainty
We show you what we don't know. Wide confidence bands mean we need more data — not that something is wrong.
Descriptive, not prescriptive
We surface tradeoffs and consequences. We never tell you what to value or how to live.
Calm over urgency
No scare tactics. No manufactured anxiety. Clear information, calmly presented.

Highest fidelity. Full audit trail.

Everything you need, in one place.

One number for your entire life.

Life Capital adds up everything you'll ever earn, save, and grow — then subtracts everything your life will cost, from rent to healthcare to taxes to raising kids. It projects this year by year, accounting for the probability that you'll be alive and healthy at each age. The result: how much room you have, in dollars and years.

Six Dimensions

Your complete balance sheet.

what you have

Financial Capital

Your savings, investments, and retirement accounts — plus what you'll save going forward. Adjusted for taxes and how easily you can actually access it.

what you'll earn

Earning Power

The total value of every future paycheck — adjusted for your industry, education, career trajectory, and how long you'll be able to work. Usually your biggest asset when you're young.

how long you'll live

Health

Your personal life expectancy built from 18 factors — not a national average. Exercise, diet, smoking, conditions, and where you live all shift your timeline and your costs.

who's in your corner

Relationships

Strong relationships boost your income, soften financial shocks, and extend your life. We measure close bonds, professional networks, and community involvement.

how well you execute

Behavioral Efficiency

Your habits shape how efficiently you turn income into wealth. Investment decisions, career growth, health maintenance, spending discipline — four channels that compound over decades.

what your life costs

Obligations

Everything you're on the hook for — healthcare, housing, food, taxes, debt, kids, insurance, and more. 15 categories, all adjusted for your age, income, and household. Projected every year.

Methodology

How Life Capital works.

We project your life forward year by year — from today until the end. Every year, we estimate what comes in and what goes out, adjusted for the likelihood you'll be alive and healthy. Then we add it all up in today's dollars.

Life Capital = Everything you'll ever have − Everything your life will cost
Projected year by year · adjusted for how long you'll live · valued in today's dollars
Each year's flows are weighted by your individual probability of being alive at that age, then discounted to present value.
What you have
Financial Capital

Your savings, investments, retirement accounts, and what you'll save in the future. Cash in hand is worth more than cash locked in a 401k — we account for that.

What you'll earn
Earning Power

The total value of your future paychecks — adjusted for your industry, education, how fast your income will grow, and how long you'll be working. This is usually your single biggest asset, especially when you're young.

Health

Your personal life expectancy based on 18 factors — exercise, smoking, diet, chronic conditions, where you live. Not a national average. Yours. Quitting smoking alone adds about 4 years. Eating well adds 3.7.

Relationships

Strong relationships boost your earnings, cushion financial shocks, and literally extend your life. We measure close bonds, professional networks, and community ties. People with less money get even more benefit from strong relationships.

Behavioral Efficiency

Your habits and personality shape how efficiently you convert income into wealth. Four channels: investment decisions, career growth, health maintenance, and spending discipline. Without a personality assessment, we assume average — no penalty, no bonus.

Retirement

You don't retire at an age.
You retire at a number.

Retirement isn't a birthday. It's the point where you no longer need to earn — where everything you have covers everything your life will cost, with room to spare, even in a bad scenario.

Most tools ask “can I retire at 65?” That picks an arbitrary age and hopes the money lasts. We flip the question: given your current trajectory, when is the earliest point where your income becomes optional?

Save more — the point moves closer. Get healthier — your costs drop and your timeline extends. Change careers — your earning curve shifts. Every decision you make moves the line. We just show you where it is.

The old way
“I'll retire at 65.” Pick an age. Save what you can. Hope it's enough. The age is arbitrary. The math is an afterthought.
The Life Capital way
Project everything forward. Find the earliest point where you're covered without a paycheck — even if markets drop, even if you live longer than expected. That's your number. Change your inputs, watch it move.
