How to Plan Your Retirement and Future Income
Plan your retirement online. Calculate your sustainable monthly income based on your contributions or find out how much you need to save each month.
What is the purpose?
This calculator helps you plan your retirement by estimating the final accumulated capital and the lifetime or temporary monthly passive income from your contributions.
Formula Used
Retirement planning comprises two phases:
- Accumulation Phase: Where the accumulated capital (
C_{acumulado}) is calculated by applying compound interest on the current balance and monthly contributions (PMT) duringnmonths:
C_{acumulado} = C_{current} × (1 + r_{pre})n + PMT × (1 + r_{pre})n - 1r_{pre}
- Retirement Phase (Sustainable Income): Where monthly disposable income (
PMT_{sustentável}) is calculated based on accumulated capital to lastmmonths with post-retirement monthly rate (r_{post}):
PMT_{sustentável} = C_{accumulated} × r_{post} × (1 + r_{post})m(1 + r_{post})m - 1
*(Note: Equivalent monthly interest rates are calculated from the annual rate by: r = (1 + R)1/12 - 1)*
How to interpret the result?
Results display:
- Sustainable Monthly Income or Required Contribution: Depending on the mode selected, it shows how much you can withdraw per month or how much you need to save.
- Accumulated Capital: The total assets estimated at the beginning of retirement.
- Total Contributed: The sum of all money invested directly.
- Total Interest Earned: The difference generated by the compound income over the two phases.
Practical Examples
If you are 30 years old, want to retire at 65, have a life expectancy of 85 years, and a current balance of $10,000.00:
- If you save $500.00 per month with an annual rate of 8% pre- and 5% post-retirement:
- Accumulated capital at age 65 will be $ 1,139,734.51.
- The sustainable monthly income until the age of 85 will be $7,747.38 per month.
- The total interest earned will be $ 1,639,371.20.
Usage Tips
- Start saving as soon as possible. The time factor is the most powerful element in compound interest in the accumulation phase.
- Adjust return rates cautiously. In the post-retirement phase, prefer lower-risk investments (conservative fixed income) with lower rates of return.
- Remember to discount projected inflation to obtain values in current purchasing power.
Important Observations
Calculations are based on constant profitability rates and pure mathematical simulations. Taxes (such as Income Tax) and fund management fees are not automatically deducted in this simulation.
Frequently Asked Questions (FAQ)
What is the sustainable income rule?
It is the calculation that defines the monthly amount that you can withdraw from your accumulated assets so that the balance lasts exactly until your expected life expectancy.
How does inflation affect my retirement?
Inflation reduces the purchasing power of money over time. To compensate, use rates of return net of inflation (real rate) in the simulation.
What is the difference between investing in Private Pensions vs. Treasury RendA+?
The RendA+ Treasury is a public government bond that pays monthly installments adjusted by the IPCA for 20 years. PGBL/VGBL pensions offer tax advantages (such as deduction and 10% IR table) and greater flexibility in terms.
How does the INSS retirement ceiling limit income?
The INSS has a maximum limit for pension payments (ceiling). Those who earn above the ceiling need to have supplementary savings or a private pension if they wish to maintain the same standard of living.
What is the accumulation phase and the usufruct phase?
The accumulation phase is the active period in which you save and invest monthly. The usufruct (or retirement) phase is the moment when you start making monthly withdrawals of capital to live off income.
How to estimate real net profitability for the long term?
Net real rates (already discounted inflation and taxes) between 4% and 6% per year are used as a conservative estimate, in line with the historical profitability of long IPCA+ bonds.
What happens if I live longer than the simulated life expectancy?
If your plan uses up all the capital and you exceed the estimated life expectancy, the monthly income stops. It is recommended to plan additional safety margins or purchase plans with lifetime income.
