Clear money math for decisions that deserve better than guesswork.
Arthonitee is a free collection of Bangladesh-focused finance calculators for savings, loans, tax and investment choices. It is built to show the number, the assumptions and the local rule behind the number.

Why this exists
A lot of financial tools answer a formula. Fewer answer the local question: what happens after source tax, product caps, Bangladesh income-tax slabs, or the way banks actually quote returns?
Sourced, dated rules
Important rates are kept in one reviewed place, so calculators do not quietly drift from the rules they depend on.
Bangla and English
Money decisions should not require switching into someone else's language or number format.
Estimates, not advice
The goal is clarity before you talk to a bank, tax adviser or savings office, not a replacement for them.
How Arthonitee works
The product keeps its calculation logic, rates and explanatory content close together. When rules change, the goal is to update the source document, the config and the calculator behavior as one system.
Local before generic
Sanchayapatra source tax, DPS/FDR conventions, excise duty and income-tax rebate matter here.
Explain the result
A final number is useful only when you can see the assumptions, deductions and trade-offs behind it.
Keep it open
The calculators are free, need no account, and are built to work well on ordinary phones.
Arthonitee is the product. Shifat is the person building it.
The calculators are the foundation. The next step is helping people compare choices, save plans and understand trade-offs in plain language.
