About Money Doubling & Tripling Calculator (72 / 114 / 144)
The rule of 72 has two lesser-known siblings: divide 114 by your return for TRIPLING time, 144 for QUADRUPLING — at 12%, money doubles in ~6 years, triples in ~9.5, quadruples in ~12. This calculator computes all of them exactly (plus the 10× milestone), turning any return assumption into a timeline of wealth multiples. Notice the compounding signature in the spacing: quadrupling takes exactly twice the doubling time (4× = two doublings), but TRIPLING arrives sooner than 1.5 doublings would suggest in linear thinking — the gaps between multiples shrink as the base grows. The 10× line makes careers concrete: at 12% it's ~20 years, meaning a ₹10 lakh decision in your 20s is a ₹1 crore decision by your 40s. These rules price life choices quickly: a ₹10 lakh car at 30 versus 10× of it at 50; a 3% expense-ratio product versus an index fund (the fee gap costs you the difference between 4× and 3× over two decades); 6% inflation tripling your living costs in ~19 years (114/6) — the same arithmetic your corpus must out-run. Multiples-and-years is simply a better language for long-term money than percentages.

Frequently asked questions
12% par paisa triple hone me kitne saal lagte hain?+
Rule of 114: 114 ÷ 12 ≈ 9.5 saal (exact 9.69). Double ~6.1 saal, quadruple ~12.2, aur 10× lagbhag 20.3 saal. In teen-chaar numbers ko yaad rakh lein — kisi bhi scheme/plan ki pitch sunte hi dimag me timeline ban jaati hai.
Why is tripling time NOT 1.5× doubling time?+
Because growth is exponential, not linear: ln(3)/ln(2) ≈ 1.585, so tripling takes ~1.58 doubling-times, not 1.5. Small distinction, big habit: thinking in logs (multiples) rather than percentages is what makes compound outcomes intuitive instead of surprising.
Inflation se cost kab triple hogi?+
114 ÷ inflation rate: 6% par ~19 saal, 7% par ~16.3 saal. Matlab aaj ka ₹50,000/month ka kharcha retirement ke 19 saal baad ₹1.5 lakh/month hoga. Corpus planning me yeh tripling-clock investments ki doubling-clock ke saamne rakh kar dekhna hi asli math hai.
What return do I need for 10× in 15 years?+
ln(10)/15 as a growth rate → about 16.6% per year, sustained — beyond long-run market averages, achievable mainly via concentrated risk, leverage or luck. For 10× over 20 years you need ~12.2%, which IS within equity's historical range. Stretching the horizon, not the return assumption, is the credible path.
