Plain-language guide
Will today's budget support the retirement income I may need?
How this estimate works
The estimate subtracts entered expenses and savings commitments from after-tax income, then projects retirement savings in today's dollars using an effective monthly rate derived from the annual real return.
Important: This is an educational estimate, not individualized financial, investment, tax, legal, insurance, or business-valuation advice.
Common questions
- What does a monthly cash flow calculator show?
- It compares the after-tax income, spending, and savings commitments you enter to show an unassigned monthly surplus or deficit.
- How is the retirement income need estimated?
- The calculator subtracts dependable retirement income from estimated retirement spending, then estimates the capital needed for the remaining annual income gap.
- Does a surplus mean my retirement plan is complete?
- No. A surplus is an illustrative result that still needs testing for taxes, longevity, health costs, irregular expenses, and lower returns.
