| Input Item | Example Value | Why It Matters |
|---|---|---|
| Initial Deposit | $5,000 | Sets the starting balance for compounding. |
| Manual Monthly Contribution | $300 | Adds voluntary savings beyond payroll deductions. |
| Payroll Deduction | 4% of salary | Automates workplace-linked saving behavior. |
| Employer Match | 50% up to 3% of salary | Shows benefit-driven account growth. |
| Annual Interest Rate | 4.5% | Measures account growth from compounding. |
| Inflation Rate | 2.5% | Converts nominal balance into real purchasing power. |
1. Payroll deduction per month
Payroll Contribution = Annual Salary × Payroll Deduction % ÷ 12
2. Employer monthly support
Employer Match = Lesser of:
Payroll Contribution × Employer Match %
or
Annual Salary × Match Cap % ÷ 12
3. Effective monthly growth rate
Monthly Rate = (1 + Annual Rate ÷ Compounding Frequency)Compounding Frequency ÷ 12 − 1
4. Monthly balance update
New Balance = Old Balance + Employee Deposit + Employer Support + Interest − Monthly Fee
5. Inflation-adjusted ending value
Real Balance = Ending Balance ÷ (1 + Inflation Rate)Years
6. Extra monthly amount to hit target
The planner uses a binary search to estimate the smallest added monthly deposit needed to reach the selected goal within the chosen time.
It helps teams explain payroll savings programs, employer support, and long-term money growth in a way employees can understand before choosing deduction amounts.
Yes. It treats manual monthly deposits and payroll-based deductions as separate inputs, then combines them in the projection for clearer workplace planning.
Employer support is based on the payroll deduction amount only. The planner also checks the annual match cap so the contribution does not exceed the stated policy.
Nominal balances can look strong while purchasing power weakens. The real value view shows what the ending balance may actually be worth over time.
It estimates how much more you should add to your manual monthly deposit to reach the chosen target by the end of the selected planning period.
Yes. It works well for benefits education, onboarding discussions, salary planning workshops, and one-on-one coaching around payroll saving habits.
The schedule increases salary using the annual raise assumption. That affects payroll deductions and may also change the employer match cap each year.
Yes. Even modest monthly fees reduce compounding over time. This planner subtracts fees every month so their cumulative drag is easy to see.
