Quick guide
How to use this calculator
- Enter the balances, contributions, income, costs, ages, plan terms, and assumptions from the scenario you want to test.
- Keep currencies, periods, and nominal-versus-real rates consistent; compare more than one plausible scenario where outcomes are uncertain.
- Use the companion results and limits to understand funding gaps, timing trade-offs, and which assumptions drive the result.
Calculation method
Calculation method
Present value discounts payments from any entered deferral; future value is measured at the end of the payment sequence, with beginning-of-period deposits compounding for one additional period.
Deterministic calculations use exact fixed-decimal arithmetic. The explicitly probabilistic success tool uses a reproducible seeded simulation and discloses its model.
Worked example
Worked example
Ten annual payments of 10,000 discounted at 5% have a present value that depends on whether payments start immediately or after one year.
Present value discounts payments from any entered deferral; future value is measured at the end of the payment sequence, with beginning-of-period deposits compounding for one additional period.

Planning scope
This is a country-neutral planning scenario using only visitor-entered amounts, rates, ages, plan terms, and time periods. It does not determine tax, statutory benefits, contribution limits, eligibility, product terms, or legal rights.
Payment timing conventions
Unless a timing selector says otherwise, recurring accumulation contributions are applied at month-end. Bridge withdrawals are valued at the beginning of each year. Pension lump-sum comparisons value pension payments at month-end. Withdrawal projections apply the return for a period before that period's withdrawal.
Return and inflation assumptions
Investment returns, inflation, education costs, earnings, healthcare costs, longevity, and plan outcomes are uncertain. Entered constant rates and simulated distributions are scenarios rather than forecasts.
No tax or statutory calculations
At the owner's direction, these calculators do not calculate tax, required distributions, government-benefit claiming, contribution limits, early-withdrawal penalties, education tax credits, or country-specific account rules.
Decision boundary
Results do not recommend a pension election, investment, withdrawal strategy, school, loan, retirement date, healthcare plan, or employment decision. Confirm plan terms and consequential choices with the relevant administrator or qualified professional.
Precision and privacy
Plain decimals accept up to 30 digits and 12 decimal places. Calculations remain in this browser and raw entered values are not submitted to 365CALCS.COM.
