A smaller investment target based on continued work is still work-dependent. Use net income and a fallback budget, not an optimistic gross side-job estimate.
Define what half-retirement would look like
The exercise assumes reduced work rather than complete financial independence. Specify hours, net pay, travel, benefits and how long you could keep doing the job. A job that fits at 45 may not be possible at 70. The popular Barista FI label does not guarantee employment or benefits.
Our fictional annual spending is MYR60,000. Dependable other income is assumed to be MYR6,000 after relevant costs, and part-time work brings MYR24,000 net per year. No specific benefit, dividend or rental is promised here.
Calculate the annual gap
The investment-funded gap is MYR60,000 − MYR6,000 − MYR24,000 = MYR30,000 a year. Dividing by an assumed initial withdrawal fraction of 3.5% gives MYR857,142.86. The fraction is a scenario input, not a safe rate established for this household.
Do not subtract portfolio dividends here and then apply a total-return withdrawal fraction to the same portfolio. That would count some investment income twice. The MYR6,000 other-income assumption is separate from the investment pot used in this calculation.
Remove the part-time income and recalculate
If part-time income stops, the gap rises to MYR54,000. At the same 3.5% assumption the modelled pot becomes MYR1,542,857.14. With only MYR857,142.86 invested, a MYR54,000 withdrawal would instead be 6.3% of that starting balance.
This is a dependency check, not a claim that either withdrawal level will succeed or fail. Health, caring duties and employer decisions can remove work income just when extra spending appears. Write which spending could change and how you would bridge the gap.

| Income case | Annual investment gap | Pot at assumed 3.5% |
|---|---|---|
| MYR24,000 work + MYR6,000 other | MYR30,000 | MYR857,142.86 |
| No work + MYR6,000 other | MYR54,000 | MYR1,542,857.14 |
| Same MYR857,142.86 pot; no work | MYR54,000 | 6.3% initial withdrawal |
Budget for a six-month interruption
Half a year without the MYR24,000 annual net job income creates MYR12,000 of missing cash, if spending and other income stay unchanged. Covering it from a separate reserve avoids an immediate extra portfolio withdrawal, but uses that reserve. It is not free income.
Do not set aside MYR12,000 and also include that same sum inside the MYR857,142.86 investment pot. If both are needed, they are separate allocations. A six-month example is not a recommendation for the correct buffer length.
Compare net pay, not the job advertisement
A gross annual side-job figure can overstate the benefit if tax, transport, equipment or childcare rise. Benefits lost by leaving full-time work may add insurance or healthcare spending. List those costs before using the gap formula. Local eligibility and employment rules need independent verification.
A realistic trial might keep your existing job while tracking actual side-job hours and costs, where your contract allows it. This article does not recommend taking a second job or reducing essential protection. It teaches how to measure the budget effect.
Keep a fallback plan beside the target
Write a low-income budget, a work-stoppage trigger and a date to reassess. If the only fallback is selling risky investments regardless of price, acknowledge that exposure rather than calling the smaller pot financially independent.
