The single most useful calculation in personal finance, and the one most people never run. Watch how much of the final number is growth rather than your own money.
Assumes the return arrives evenly and gets reinvested, and that you never miss a month. Real returns arrive lumpy: the shape holds, the exact number won't. চক্রবৃদ্ধি কী?

Modelled simply: sanchayapatra profit is treated as paid out and taxed as it's paid, FDR interest as compounding annually and taxed on the interest. Real products differ: purchase ceilings, quarterly versus maturity payment, and early-encashment penalties can outweigh the rate gap entirely. Confirm current rates with Bangladesh Bank and your branch. সঞ্চয়পত্র · এফডিআর
What your money will really be worthমূল্যস্ফীতি ও প্রকৃত রিটার্ন
A number that doesn't change still shrinks. This is the calculation that explains why money under the mattress, or in an account paying less than inflation, quietly loses.
Real return uses the Fisher relation, (1 + return) ÷ (1 + inflation) − 1, not the subtraction people usually do, which flatters the answer at high rates. মূল্যস্ফীতি কী?
What a loan actually costsকিস্তি ও মোট সুদের হিসাব
The instalment is the number you're shown. The total interest is the number that matters, and the term length moves it more than the rate.
Standard reducing-balance EMI at a fixed rate. Processing fees, insurance and rate resets aren't in here: ask for the total cost of credit in writing before signing anything.
How much of this share you can actually buyঝুঁকি অনুযায়ী পজিশন সাইজ
Most first-year losses aren't bad picks: they're good picks bought too big. Decide the most you'll lose before you decide how much to buy, and the size follows from arithmetic instead of nerve.
A stop-loss is a decision, not a guarantee: DSE circuit breakers and thin liquidity mean the price you get out at can be worse than the one you planned. Size as though the stop might slip. ঝুঁকি ও রিটার্ন
