Annuity-style accumulation
Use the annuity calculator when the question is how a starting balance, annual additions, monthly additions, growth rate, years, and contribution timing could build before payout.

Retirement Financial Calculators
Retirement calculators help separate accumulation estimates, payout math, workplace-plan scenarios, required-minimum-distribution estimates, and broad retirement planning assumptions.
Start with the retirement question you need to estimate: annuity-style accumulation, payout timing, retirement savings or withdrawals, 401(k) contributions and match, or a US RMD calculation.

Retirement calculator paths
Each path below points to one canonical calculator and its formula notes. Generated examples and child help routes are intentionally excluded from this category hub.
Payout from a starting balance
Use the annuity payout calculator when a starting balance, fixed payout term, fixed payout amount, payout frequency, and entered return assumption need to be modeled mechanically.
Broad retirement planning estimate
Use the retirement calculator for retirement-need, savings-required, withdrawal-amount, or money-last-duration scenarios from age, income, savings, return, inflation, target, and withdrawal assumptions.
401(k) projection and match scenarios
Use the 401K calculator when the estimate depends on salary, employee contribution rate, employer match tiers, salary growth, return, inflation, retirement age, or a simplified early-withdrawal cost.
Required minimum distribution estimate
Use the RMD calculator when the question is a US required-minimum-distribution estimate from account balance, birth year, RMD year, beneficiary age gap, and return assumptions.
Annuity Calculator
Estimate deferred annuity accumulation from starting principal, regular additions, growth rate, and contribution timing.
Annuity Payout Calculator
Estimate a fixed-length annuity payout amount or how long an annuity can last with a fixed payout.
Retirement Calculator
Estimate retirement savings needs, savings required, monthly withdrawal capacity, and how long savings may last.
401K Calculator
Project a 401(k) balance, estimate early withdrawal costs, and find the salary contribution needed to capture an employer match.
RMD Calculator
Estimate a required minimum distribution from a tax-deferred retirement account and project next year's RMD.
Source boundaries for estimates
- These calculators use the ages, balances, contributions, income, growth, inflation, payout, withdrawal, account, beneficiary, and timing assumptions you enter. They do not pull live annuity rates, plan fees, investment menus, Social Security estimates, pension valuations, tax tables, provider quotes, payroll records, account statements, or legal documents.
- Retirement outputs are educational estimates, not financial advice, not tax advice, not legal advice, not pension advice, not investment advice, not insurance advice, not a provider quote, not an annuity illustration, not a benefits determination, not a plan-administrator decision, and not a personalised retirement recommendation.
- Use current IRS retirement-plan and RMD materials, DOL/EBSA retirement-plan guidance, SEC and Investor.gov materials, FCA and MoneyHelper materials, plan documents, provider disclosures, tax authorities, pension administrators, insurers, payroll records, and qualified professional advice before acting on product-specific, tax-specific, pension-specific, jurisdiction-specific, or regulated-advice questions.
