Barista FIRE calculator

Estimate a portfolio target for the gap between planned annual spending and part-time take-home income. Include health coverage and other costs in your budget; eligibility and taxes are not modeled.

Illustrative income-gap formula · Snowballr calculation
Portfolio target = remaining annual spending gap ÷ chosen initial withdrawal rate
For example, $60,000 in annual spending less $25,000 in take-home work income leaves a $35,000 gap. At a 4% assumption, the arithmetic target is $875,000.
Work benefits and health coverage vary. Include expected costs in spending and do not treat unpriced benefits as income in this calculator.

Barista FIRE math

This illustration splits the spending plan between invested assets and take-home work income:

  1. Portfolio: target equals the annual spending gap divided by the selected initial withdrawal-rate assumption
  2. Work income: annual take-home pay assumed available toward spending; benefits are not assigned a dollar value
Portfolio target = (Annual spending - take-home work income) / withdrawal-rate assumption

Example:
  $60k spending - $25k part-time = $35k gap
  $35k gap / 4% = $875,000

Work and benefit assumptions

Employer benefit eligibility and plan costs vary by role and can change; verify current details directly with the employer. This calculator assigns no cash value to health coverage, so include expected premiums and out-of-pocket costs in annual spending. U.S. early retirees can compare Marketplace coverage information at HealthCare.gov.

$80k$30k$1.25M63% of $2.0M
$100k$35k$1.625M65% of $2.5M

Rows assume the work-income amount is annual take-home pay available for spending, all coverage costs are included in annual spending, and the portfolio target is the gap divided by 4%. This is arithmetic only; taxes, job availability and portfolio longevity are not modeled.

Do I really need a job for health insurance?

This calculator does not determine coverage eligibility or premiums. In the U.S., check current plan and subsidy estimates for your household and location at HealthCare.gov, and include expected costs in annual spending.
