PrinciplesReturn

The gain or loss on an investment over a period, relative to the amount invested.

Why it matters

It helps compare performance when risk, fees and time are also considered.

Read the full definition →
PrinciplesInflation

The general rise in prices that reduces money’s purchasing power.

Why it matters

Read the full definition →
PrinciplesFees

Costs charged to manage, buy or hold an investment.

Why it matters

Even small fees directly reduce the return kept by the saver.

What to watch

Why it matters

It gives a clearer view of your overall financial position.

Read the full definition →
PrinciplesReal return

An investment return after accounting for inflation.

Why it matters

It more accurately measures how your capital’s purchasing power changes.

Build your planRebalancing

The process of returning a portfolio to its target allocation after market movements.

Why it matters

Build your planSaving capacity

The amount a household can set aside after essential expenses and commitments.

Why it matters

It helps build a sustainable roadmap rather than a theoretical goal.

Simple example

With €2,500 of income and €2,150 of expenses, theoretical saving capacity is €350.

Read the full definition →
Build your planSavings rate

The share of disposable income saved over a period.

Why it matters

It tracks saving effort independently of the absolute income level.

What to watch

A high rate is not desirable if it prevents essential spending or creates debt.

Simple example

Saving €300 from €2,000 of disposable income represents a 15% savings rate.

Read the full definition →
Build your planEmergency fund

An accessible reserve intended to absorb unexpected expenses or a temporary income drop.

Build your planFIRE movement

An approach to financial independence, sometimes linked to early retirement, built through a high savings rate and invested assets.

Why it matters

It connects spending, saving, target capital and greater freedom over work.

What to watch

FIRE is neither a financial product nor a guarantee: tax, inflation, healthcare, pensions and returns must be considered.

Simple example

A household may use FIRE to estimate the capital needed to cover part of its spending.

Read the full definition →
Build your planFIRE number

An estimate of the capital needed to fund annual spending at a chosen withdrawal rate.

Why it matters

It turns an abstract financial-independence goal into a measurable estimate.

What to watch

The result is highly sensitive to future spending, withdrawal rate, duration, tax and inflation.

Simple example

With €30,000 of spending and a hypothetical 3% withdrawal rate, the indicative capital would be €1,000,000.

Read the full definition →
Build your planWithdrawal rate

The share of a portfolio withdrawn over a period to fund spending.

Why it matters

It links spending needs to the capital required and the intended duration.

What to watch

A rate that is too high may deplete capital, while a cautious rate still cannot guarantee sustainability.

Simple example

Withdrawing €30,000 from a €1,000,000 portfolio represents 3% in the first year.

Read the full definition →
Principles4% rule

A historical rule of thumb often used to illustrate an initial 4% portfolio withdrawal, then adjusted for inflation.

Why it matters

It provides an educational starting point for thinking about long-term withdrawals.

What to watch

It is neither universal nor guaranteed; country, tax, fees, allocation, duration and markets change the outcome.

Simple example

The rule would imply an indicative initial withdrawal of €20,000 from €500,000.

Read the full definition →
PrinciplesSequence-of-returns risk

The risk that major losses early in the withdrawal period permanently weaken a portfolio.

Why it matters

It shows that the order of returns matters when a portfolio funds regular withdrawals.

What to watch

Two portfolios with the same average return may last very different lengths of time depending on the order of good and bad years.

Simple example

A major fall just after retirement begins may force more assets to be sold at low prices.

Read the full definition →
Build your planLean FIRE

A form of FIRE based on deliberately restrained spending.

Why it matters

It may lower the target capital and make the goal quicker to reach.

What to watch

An overly tight budget may be hard to sustain and underestimate healthcare, family, housing or emergencies.

Simple example

A Lean FIRE plan tests several budgets rather than one theoretical minimum.

Read the full definition →
Build your planCoast FIRE

A stage where existing invested assets could, under the assumptions used, grow to the retirement target without major new contributions.

Why it matters

It helps assess whether saving effort can be reduced while keeping a long-term goal.

What to watch

The outcome remains highly dependent on future returns, inflation, fees and time remaining.

Simple example

A person may keep working to cover current spending while leaving invested assets to grow.

Read the full definition →
Build your planBarista FIRE

A strategy combining partially built wealth with reduced or supplementary employment.

Why it matters

It may reduce withdrawals and maintain some income before full financial independence.

What to watch

Employment income, social protection and job stability must be assessed carefully.

Simple example

Part-time income may cover part of spending while the portfolio funds the remainder.
