Personal Finance Calculators

Sixteen tools for tracking where your money is and where it's going.

Personal finance splits into three questions: what am I worth right now, where is my money going each month, and when can I stop working. The tools below map onto those three questions rather than onto financial products, because that's the order most people actually work through them.

If you're starting cold, run the net worth calculator first. Almost every other number here — your savings rate, your FIRE date, how long a career break could last — depends on knowing your current position, and most people are off by more than they expect.

Know where you stand

Start here. These establish the baseline numbers the rest of the tools build on.

Net Worth Calculator

Total assets minus total liabilities.

Income Analysis Suite

Net income, DTI, and savings rate.

Comprehensive Budget Manager

Detailed monthly budget with savings tracking.

024 tools

Plan for financial independence

Four flavours of the same question, differing in how much you want to keep working. Full FIRE means never working again; Coast FIRE means you've saved enough that compounding alone finishes the job; Barista FIRE assumes part-time income covers the gap.

FIRE Calculator

Plan early retirement.

Financial Independence (FI)

Calculate your freedom number.

Coast FIRE Calculator

How much to invest now, then stop — and let compounding finish the job.

Barista FIRE Calculator

How part-time income shrinks your FIRE number and how many years earlier you can semi-retire.

032 tools

Save toward a target

Use goal-based savings when you have several targets at once with different deadlines. Use the unified savings calculator when you want fine control over compounding frequency and contribution timing.

Goal-Based Savings

Track multiple financial targets.

Unified Savings Calculator

Advanced savings projection with compounding control.

044 tools

Test a decision before you make it

Recurring costs and one-off purchases both look small in isolation and large over a decade. These put a real number on them.

Subscription Cost Analyzer

Total yearly cost of monthly subs.

Break-Even Time

When does a purchase pay off?

Lifestyle Affordability

Can you afford your lifestyle?

Personal Allowance

Safe-to-spend daily limit.

053 tools

Adjust for where and when

A salary means different things in different cities, and in different decades. These convert between them.

Cost of Living Comparison Calculator

Compare living costs between two cities.

Inflation Impact

Future purchasing power.

Currency & Money Converter

Convert money with live currency exchange rates.

Common questions

Short answers to what people ask most before picking a tool.

Which calculator should I use first?+
The net worth calculator. It takes about five minutes and produces the single number that every other tool on this page needs as an input. Without it you're estimating your savings rate and retirement date from a guess.
What's the difference between the FIRE calculator and the FI number calculator?+
The FI number calculator answers 'how big does my portfolio need to be' — a single target figure, usually annual expenses multiplied by 25. The FIRE calculator answers 'when do I get there' by projecting your current savings and contribution rate forward against that target.
Do these calculators save my financial data?+
No. Every calculation runs entirely in your browser using JavaScript. Your income, balances, and expenses are never transmitted to a server, and there's no account to create. Closing the tab discards everything.
How accurate are the projections?+
The arithmetic is exact, but any projection depends on assumptions you supply — investment return, inflation, and future contributions. Small changes to an assumed return rate compound into large differences over 20 or 30 years, so it's worth running an optimistic and a pessimistic case rather than treating one output as a forecast.
