  • Additional debt principal: –

How the calculation works

Let G be gross employee income, T taxes, P employee pre-tax contributions, S employee post-tax contributions, D additional debt principal and M employer match. Employee savings = P + S. Debt principal and employer match are separate.

Gross rate = (P + S + M) / (G + M) × 100; saved per month = P + S + M; after-tax-income rate = (P + S) / (G − T) × 100

Take-home cash pay is G − T − P, assuming no other payroll deductions. The after-tax-income measure includes P as income retained; it is a disclosed planning convention, not a universal definition. Gross Saving Rate = (P + S + M) / (G + M) × 100, assuming gross income excludes the match. Wealth-building allocations = P + S + D + M; they are not cash savings or measured net-worth growth.

The chart allocates gross employee income only; employer match is outside its denominator. Enter only the principal portion of extra debt payments, excluding interest and fees.

Key assumptions

  • All amounts are monthly and funded by the same period of employee income; no other payroll deductions are modeled.
  • Employee savings include cash savings and investment contributions, but exclude asset gains, employer contributions and debt principal.
  • An employer match may exceed employee contributions; it changes Gross Saving Rate and Saved Per Month when selected, but does not change Net Saving Rate.

Worked example

Monthly US-dollar example: gross income 8,500; taxes 1,700; pre-tax contributions 850; post-tax contributions 500; additional debt principal 200; employer match 250.

  • Employee savings contributions: 850 + 500 = 1,350
  • Take-home cash pay: 8,500 − 1,700 − 850 = 5,950
  • Gross Saving Rate (including employer contribution): 1,600 ÷ 8,750 = 18.3%
  • After-tax-income-basis savings rate: 1,350 ÷ 6,800 = 19.9%
  • Additional debt principal: 200; employer contribution: 250 (both separate from employee savings)
  • Wealth-building allocations: 1,350 + 200 + 250 = 1,800
  • Saved Per Month (including employer contribution): 1,350 + 250 = 1,600

Wealth-building allocations combine different uses of money; they do not measure realized net-worth growth.

How to interpret the result

Compare like-for-like definitions. The after-tax-income denominator includes employee pre-tax contributions and is different from take-home cash pay. The band describes the percentage only; it is not a recommendation.

Common mistakes

  • Using annual figures in a monthly form.
  • Counting spending on assets that lose value as saving.
  • Including a one-off bonus as if it will recur.
  • Comparing your rate with someone else’s without checking that the same items are counted.
