Multi-Job Salary Calculator
Track several part-time, freelance, weekend or platform jobs on one calendar and estimate monthly take-home pay, effective hourly income and goal progress. It helps compare jobs separately instead of mixing every income source into one rough total.
01Manage each jobSave each job with its own name, color, hourly wage, work hours, fee rules and allowance settings so separate income sources stay clear.
02Calendar entryAdd more than one job to the same date and keep a clean daily record for mixed schedules, double shifts or weekend work.
03Income goal trackingCompare monthly take-home pay with your target and see whether extra hours are actually moving you closer to your income goal.

Multi-Job Salary Calculator
Track dated shifts across jobs, calculate pay and entered deductions, and estimate weekly paid rest using a clearly limited Korean-style model.

Two jobs
- Input
- Job A: 20 hours × 10; job B: 12 hours × 15; no deductions or allowance
- Result
- Total base pay 380
Amounts use the displayed currency; example wages are not local minimum-wage claims.
Entered deduction
- Input
- 5 hours × 120; 3% deduction
- Result
- Gross 600; deduction 18; net 582
The selected percentage is applied arithmetically, without identifying a tax regime.
How it works
Each record rounds hours × wage to a whole unit and caps deductions at gross pay. For the same job in a Sunday–Saturday week, allowance-enabled records reaching 15 hours receive hours/5 × wage × min(1,40/weekly hours), rounded per record. Monthly totals include only this month’s records, while qualification also uses adjoining months.
Limitations
- Weekly rest is a Korean-style estimate, not a legal entitlement assessment in any country.
- Contracts, attendance, overtime, night premiums and actual tax or insurance are not assessed.
- Changing defaults does not rewrite existing shifts. Different jobs do not share qualifying hours.
- Records and currency displays are separated by language; old shared records remain on the Korean page.

Separate effort, staffing and price so the assumptions behind an estimate remain visible. A person-day is the number of working hours you choose, not a promised calendar day.
Frequently asked questions
Are 15 recorded hours enough to establish entitlement?
No. The estimate cannot verify contracted hours, attendance or other legal conditions.
Can I change past pay by changing the default wage?
No. Remove and re-enter the relevant saved shift using the intended values.
Why are old records missing after a language switch?
Languages now have separate records to prevent relabelling old amounts as another currency. Older shared records are retained in Korean.
