Rentenrechner - Ihre Rente is a free Android app developed by Kapitalklar that gives you a closer look at your future statutory pension in old age. The app processes various factors that you can enter, such as your vintage, monthly gross income, future salary development, previous pension contributions, previous pension contribution years, desired age of entry, and place of residence (Neues / Altes Bundesland). As a result, the app shows you your stated nominal pension at the beginning of retirement with several parameters, including your accumulated pension points, the expected value of a pension point, your gross pension without discounts, your pension deduction for possible early retirement, your share of health insurance, your share of the long-term care insurance, the resulting net pension, and possibly a note on whether another income tax would be applied to the pension.

The Pro version of the app is also available, which is fully ad-free and has several advantages, including a detailed breakdown of the income tax calculation and the taxable portion of the pension, the option to turn off the clear launcher at the beginning, and all other future features at no additional cost.
