One exact question per page, answered with a number under stated assumptions — each with the calculator loaded and ready to change.

How much do I need to invest monthly to reach $1 million in 20 years?To reach $1,000,000 in 20 years at a 7% return, you would invest about $1,970 a month under these assumptions — and less than half of the total comes from your own contributions. Solve it live for any target.
How much do I need to invest to reach $500,000 in 15 years?To reach $500,000 in 15 years at a 7% return, you would invest about $1,610 a month under these assumptions — with a shorter horizon, more of the goal comes from your own contributions. Solve it live.
What is $500 a month at 7% for 30 years?Investing $500 a month for 30 years at a 7% return grows to about $585,000 under these assumptions — roughly $180,000 contributed and $405,000 from compounding. Change the inputs in a live calculator.
What is $10,000 invested at 7% for 30 years?A one-time $10,000 investment at 7% for 30 years grows to about $76,000 under these assumptions — roughly 7.6× the original amount, with no further contributions. Adjust the inputs live.
What is the Coast FIRE number at age 30?At 30, with $40k of annual expenses and a 4% withdrawal rate, the Coast FIRE number is about $222,000 under a 7% return — lower than at 35 because compounding has five more years. Adjust the assumptions live.
What is the Coast FIRE number at age 35?At 35, with $40k of annual expenses and a 4% withdrawal rate, the Coast FIRE number is about $276,000 under a 7% return. See the assumptions and adjust them in a live calculator.
What is the Coast FIRE number at age 40?At 40, with $40k of annual expenses and a 4% withdrawal rate, the Coast FIRE number is about $342,000 under a 7% return. See why it is higher than at 30 or 35 and adjust the assumptions live.
How long will $1 million last in retirement?Withdrawing 4% a year (inflation-adjusted) from $1 million, at a 4.5% return and 2.5% inflation, the balance lasts about 34 years under these assumptions. Change the withdrawal rate and return in a live calculator.
How much do I need to retire on $50,000 a year?At a 4% withdrawal rate you'd need about $1.25 million to draw $50,000 a year, rising with inflation. See how a 3.5% or 5% rate changes the target in a live calculator.
How much can I safely withdraw from $500,000?At a 4% withdrawal rate, $500,000 provides about $20,000 a year (~$1,667 a month), rising with inflation and lasting ~34 years under these assumptions. Adjust the rate in a live calculator.
How much do I need invested to earn $1,000 a month in dividends?At a 4% dividend yield you'd need about $300,000 invested to earn $1,000 a month; about $400,000 at 3% and $240,000 at 5%. See the capital at any yield in a live calculator.
What will $100,000 be worth in 20 years with inflation?At 2.5% inflation, $100,000 keeps only about $61,000 of today's buying power after 20 years — a loss of roughly 39%. See the year-by-year erosion and change the inflation rate live.
