High return, fully transparent.

up to82%

*Total-return basis. Actual 81.6% (¥600k rate, 6th yr); year one from 75.8%.

We don't hide the rate. It starts at 65% and rises +1% every year, automatically and regardless of reviews, reaching 70% in year six. It never goes down. The whole formula is on this page.

Let's just talk first Estimate my salary

Where 100% of project billing goes, including the company's share.

Here's where your rate goes.

What lands on your payslip is 65–70% of your rate. Counting what the company also pays in for you (insurance, workers' comp, commute), it's 76–82%. The rest is the company's cut.

We open up everything inside that 82%.

Salary, insurance, workers' comp, commute, down to the company's cut.

up to82%total-return basis (what the company invests, not your take-home)

How much a company "returns" depends on what it counts. Most figures above 80% add the company's contributions on top of salary. Measured the way others measure, we're at 76–82%. And we'll show you every line of that math.

*"Up to 82%" rounds up an actual 81.6% (rate ¥600k, 6th year). Year one starts at 75.8%. Total return is what the company invests, not your take-home (income tax and the employee share of insurance come out of the payslip figure). Basis: under 40, Kyokai Kenpo Tokyo, FY2026 rates.

Basis: ¥600k rate, under 40, Kyokai Kenpo Tokyo, FY2026 rates, standard-remuneration model. Individual figures move about ±1% with age, dependents and revisions; 40 and over adds long-term care insurance on the employer side. The calculator computes actual values from your input rate (since commute is a fixed amount, the total-return % dips slightly as the rate rises).

Year one is 65%, then +1% each year (capped at 70% in year six). Total return runs from 75.8% in year one up to 81.6%.

Payslip monthly = rate × payslip rate. Payslip rate = 65% in year one, +1%/yr (max 70%). Annual = monthly × 12. Total return = payslip + insurance + workers' comp + commute. Take-home is the payslip figure minus income tax and your share of insurance.

Example: ¥800k rate, year two (66% payslip) → about ¥530k/mo × 12 = about ¥6.36M/yr. Just one example, not an average or a guarantee.

With the company-leased housing program, the same pay leaves more in your hands.

Under the company-leased housing program, part of your rent is drawn from salary, which lowers your standard monthly remuneration. Your monthly social insurance drops, your taxable income falls too, so the same payslip leaves more in your pocket. We use the same model employee from the rate breakdown above (¥600k rate, year one, ¥390k salary).

Back in your take-home+¥102,168/yrThat's +¥8,514 a month

That's the social-insurance gap alone. On top of it, lower taxable income also trims your income and resident tax.

Assumptions: same model as the rate breakdown above (¥600k rate, year one, ¥390k salary), ¥155k company-leased housing rent (you cover 50% of the rent equivalent, ¥77,500, drawn from salary), 35 sqm, under 40, Kyokai Kenpo Tokyo, FY2026 rates, standard-monthly-remuneration basis. Figures change with rent, salary and floor area.
