Annual income your portfolio supports at 4% (or your chosen SWR) — Trinity-study context and Indian caveats.

Annual withdrawal
Monthly income
Corpus as expense multiple

Formula

Year-1 withdrawal = corpus × SWR; subsequent years adjust THAT amount for inflation (not 4% of each year's balance)

About 4% Rule Calculator — Safe Withdrawal

The 4% rule compresses the Trinity study's finding into one number: withdrawing 4% of a 50-75% stock portfolio in year one, then adjusting that DOLLAR amount for inflation annually, survived essentially every historical 30-year US retirement. A $1M portfolio thus supports $40,000/year — equivalently, retirement costs 25× annual expenses, the multiplication that powers the entire FIRE movement. Understand what it is and isn't: a HISTORICAL worst-case planning heuristic (most retirements following it ended with MORE money than they started — the median outcome quadrupled), not a guarantee; it assumed US returns (international datasets suggest 3-3.5%), 30 years (early retirees planning 50 should study 3.25-3.5%), and zero fees (a 1% advisor fee effectively turns 4% into 3%). The slider above prices every variant instantly. Modern practice softens the mechanical rule: GUARDRAILS (cut withdrawals ~10% after bad years, raise after great ones) historically supported 4.5-5%+ starting rates; sequence-of-returns risk concentrates in the first decade (a crash early hurts far more than late — hence bond tents and cash buckets); and India-specific users should note higher inflation + shorter equity history argue for 3-3.5% SWRs, or — better — the bucket strategies our SWP and retirement-corpus calculators model directly.

Frequently asked questions

Is the 4% rule still valid today?+

As a planning anchor, yes; as a contract, it never was. Critics cite lower expected returns; supporters note it already encodes the worst historical sequences (1929, 1966 stagflation). Current research clusters at 3.3-4.3% depending on horizon and flexibility. Pragmatic answer: plan at 3.5-4%, retire with the ABILITY to flex spending 10-15% — flexibility is worth more than precision.

4% har saal ke balance ka ya pehle saal ka?+

PEHLE saal ka, phir us RAQAM ko inflation se badhate jaana — balance ka 4% har saal nikaalna alag (aur zyada conservative) strategy hai jisme income volatile ho jaati hai par corpus kabhi khatam nahi hota. Classic rule fixed-real-income deta hai; percent-of-balance variable income. Dono valid hain — bas confuse karke aadha-aadha mat karna.

India me 4% rule chalega ya nahi?+

Savdhani se: Indian inflation (6%+) US (3%) se zyada hai aur equity-history chhoti — direct 4% import risky hai. Indian FIRE community 3-3.5% (28-33× expenses) par converge karti hai, ya hybrid approach: pehle 5-7 saal ka kharcha debt-bucket me + baaki equity par 4-5% type withdrawals. Hamara retirement-corpus calculator Indian inputs ke saath wahi two-phase math karta hai.

What about sequence-of-returns risk?+

The rule's real enemy: a 40% crash in retirement year 2 with fixed withdrawals can doom a portfolio the AVERAGE return said was fine. Defenses: 2-3 years of cash/bonds spent during crashes (bucket strategy), guardrail spending cuts in down years, and part-time income early in retirement. The first decade decides everything; plan its defense specifically.
