What is the Barista FIRE Calculator?
The Barista FIRE Calculator helps you explore whether semi-retirement could work for you in the UK. It looks at a mix of part-time income, investments, and pensions to estimate whether you can step away from full-time work while still covering your spending.
Instead of asking “Can I fully retire?”, this tool focuses on a more flexible question:
How much do I need so that work becomes optional or lower stress?
How the Calculator Works?
This calculator models your finances in two phases: the build-up to semi-retirement and the years after you reach your Barista FIRE point.
It uses your inputs on savings, investments, income, and spending to estimate how your pots might grow over time. Once you reach your target level, it models how withdrawals, part-time income, and pensions combine to support your lifestyle.
The model assumes steady growth and applies a withdrawal rate to estimate the pot size required. It also checks whether your plan is sustainable over time by projecting forward to later life.
Step 1: Enter Your Details
Add your age, target annual spending, and expected part-time income. You can also include how long you plan to keep working in a reduced capacity.
Step 2: Add Your Assets and Assumptions
Input your pension, ISA, and general investment balances, along with any ongoing contributions. Include optional elements such as a cash buffer, State Pension, DB pension, or other income like rental or dividends
Step 3: Review Your Results
See your estimated Barista FIRE number, when you might reach it, and whether you are currently on track. The tool also shows how your money is split between accessible and locked pots, and how withdrawals might look over time.

What is the Barista FIRE Calculator?
The Barista FIRE Calculator is a planning tool that shows whether you can move to part-time or lower-stress work while using your investments to support the rest of your lifestyle. It estimates how much you need, when you might get there, and how sustainable your plan looks over time.

What is “Barista FIRE”?
Barista FIRE is a type of financial independence where you stop full-time work but continue earning some income through part-time or lower-pressure work.
How is the “Barista FIRE number” calculated?
The calculator estimates the size of investment pot needed to support your remaining spending after income. It uses a withdrawal rate to convert your income gap into a target portfolio size.
Does this include pensions?
Yes. You can include defined contribution pensions, DB pensions, and the State Pension. The model also shows how pension access timing affects your plan.
What is the “bridge” period?
If you reach semi-retirement before accessing your pension, the bridge is the period where you rely on ISAs, cash, or other accessible assets before pension income begins.
What if I reduce or stop part-time work later?
You can adjust how long you expect to earn part-time income. The calculator will show how this affects your required pot size and sustainability.
Does this include tax or fees?
No. The model uses simplified, gross assumptions. It does not account for personal tax, product charges, or investment fees.
How accurate are the results?
The results are directional rather than precise. They are designed to help you explore scenarios and understand trade-offs, not to give exact forecasts.
Will I run out of money?
The calculator includes a basic sustainability check, showing whether your plan lasts to around age 90 based on your assumptions.
