🏦 Retirement Calculator

เกี่ยวกับเครื่องคิดเลขนี้

A retirement calculator projects how much your savings could grow by the time you retire, from your current age, retirement age, current balance, monthly contribution and an expected annual return. Each month it adds your contribution and applies one-twelfth of the return to the running balance, compounding year after year until your retirement age, then splits the final pot into what you paid in versus what investment growth added.

For example, starting at age 30 with 20,000 saved and adding 500 a month at a 6% annual return, the balance grows to roughly 875,000 by age 65. Of that, only about 230,000 is money you actually contributed — the remaining 640,000 or so is compound growth. Set an inflation rate under advanced options to also see the pot in today’s money.

Use it to check whether your saving rate is on track, to see how retiring a few years later or nudging up the monthly contribution changes the outcome, and to grasp how much of a nest egg comes from decades of compounding rather than from deposits alone.
