Frequently Asked Questions

Everything you need to know.

What does an example Retirement Income Planner calculation look like?
Using this calculator's own default assumptions, a portfolio balance of $1,000,000, planned withdrawal rate of 4% and social security monthly of $2,400 produces an estimated after-tax income after healthcare of $4,948 and portfolio monthly income of $3,333. Enter your own numbers above to see how it changes for your situation.
How does the calculator handle taxes on retirement income?
The calculator applies your estimated tax rate to your gross retirement income, then subtracts those taxes and healthcare premiums from what you receive. This shows your actual after-tax, after-healthcare spendable cash: the amount available for living expenses. Different income sources may be taxed differently in reality, but this calculator uses a blended rate to estimate the overall tax impact.
What does the conservative portfolio income reference mean?
The conservative withdrawal reference shows an alternative income figure based on lower-risk withdrawal assumptions. It serves as a benchmark to compare against your planned withdrawal rate, helping you see whether your planned withdrawals align with more cautious long-term sustainability guidelines or whether you're taking on more portfolio risk to meet your spending goals.
Is the Retirement Income Planner Calculator 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 Income Planner Calculator 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?

How does SwitchWize choose related offers?

Where can I see the ranking methodology?

Why This Matters

Retirement planning requires knowing exactly how much income you'll receive each month and whether it covers your expenses. This calculator shows you the gap between what you'll spend and what your portfolio, Social Security, pensions, and other sources will provide, so you can adjust your withdrawal strategy, spending, or work timeline before retirement begins. Understanding this gap early lets you make trade-offs between drawing down savings faster, delaying retirement, or reducing planned expenses.
