Retirement Paycheck Builder | Monthly Cash Budget

Compare retirement cash income with spending, healthcare premiums and a budget tax reserve you choose. This does not calculate your tax bill.

Quick answer: Add your monthly cash income and portfolio withdrawals. Subtract your chosen tax reserve, separately entered health premiums and a monthly cash reserve set-aside. Compare what remains with your spending target. This is a budget estimate, not a tax calculation or a promise your savings will last.

Next best move

Compare this cash budget with your actual tax bill and account rules before changing distributions. The tax reserve is your assumption, not a tax-return estimate.

4% withdrawal reference

$0 monthly difference from a simple 4% annual portfolio-withdrawal reference. A negative number means your entered withdrawal exceeds that reference. This is not a safe-withdrawal guarantee.

Cash bucket gap

$41,600 more cash would meet the selected reserve target before market withdrawals.

Annual portfolio draw

The plan would pull $36,000 per year from investments before market returns, tax-law changes, and required distributions.

Frequently Asked Questions

Everything you need to know.

Does this calculate the tax due on my retirement income?
No. It applies your chosen budget tax-reserve percentage to total gross cash income, including Social Security. Some cash income may not be taxable. The result is a cash-budget illustration, not a tax-return estimate or withholding instruction.
Does a withdrawal below 4% mean my savings will last?
No. The calculator compares your entered annual withdrawal with your current portfolio balance. The 4% figure is a reference, not a guaranteed safe withdrawal rate. It does not test future investment returns or the length of your retirement.
Which healthcare costs should I enter separately?
Enter premiums in the healthcare-premium field and exclude those same premiums from the spending target. Keep doctor visits, prescriptions and other medical expenses in spending. This avoids counting the separately entered premiums twice.
Is the Retirement Paycheck Builder free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Retirement Paycheck Builder affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?
Use the recommendation module on this page to open retirement planner, or run Money Map to compare this investing & retirement decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (brokerage) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
Where can I see the ranking methodology?
The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.
Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

Social Security, pensions and portfolio withdrawals may arrive separately. Putting them in one monthly cash budget helps you compare the total with spending and reserve set-asides. This calculator subtracts the tax-reserve percentage you enter from gross cash income; it does not determine which income is taxable or estimate federal or state tax due. A monthly surplus does not establish that your savings will last.

How to Use It

  1. 1Enter monthly gross Social Security, pension, other cash income and planned portfolio withdrawals, plus your invested balance.
  2. 2Choose a budget tax-reserve percentage, enter healthcare premiums separately and add any monthly cash reserve set-aside.
  3. 3Enter spending excluding the separately entered premiums; keep doctor visits, prescriptions and other medical expenses in spending.
  4. 4Compare the monthly budget gap, withdrawal reference and cash reserve target. Review actual taxes and account rules before changing distributions.
