  • 1Set ages, income and pension in today's money.
  • 2We adjust both returns for inflation and calculate withdrawal present value.
  • 3We calculate month-end savings required to reach target capital.

Complete guide: Retirement Savings

Updated:

Target capital funds the gap between desired income and your entered pension. Public pensions and contribution requirements are not calculated. Income of 1,000 monthly over 20 years at zero return and inflation needs 240,000; saving over 30 years with no initial balance requires 666.67 monthly.

All flows are expressed in today's purchasing power. The real rate is (1 + nominal return) / (1 + inflation) − 1, converted to its equivalent monthly rate. Deposits and withdrawals happen at month-end; constant real contributions must rise nominally with inflation. The entered pension is also assumed constant in purchasing power, not a frozen nominal benefit.

The target is a finite annuity consuming capital at the final age, not a lifetime annuity or a 4% rule. It excludes inheritance, volatility, sequence risk and unexpected expenses. Enter returns net of taxes and fees, compare scenarios and extend the horizon for a larger safety margin.

Currencies cover Venezuela, Mexico, Spain, Colombia, the United States, Argentina, Chile, Uruguay, Paraguay, Peru, Bolivia, Ecuador, Costa Rica, the Dominican Republic and Brazil. These are universal financial calculations without exchange conversion or automatic national tax or benefit rules. Defaults are examples; rates are assumptions, not current quotes or guarantees.

Frequently asked questions

Does monthly saving rise with inflation?

Yes, the result is constant in today's money; its nominal amount must rise with assumed inflation. It is not a fixed nominal payment.

Does this guarantee lifelong funding?

No. It funds only through the final age under constant returns. Longer life, losses or different inflation may exhaust funds earlier.

Can I share my results?

Yes. The link preserves currency, amounts and options; recipients can see these inputs, including debt names and balances. Do not share information you want to keep private.
