Tax and pay

Tax, budget, VAT, and salary

Tax uses one editable slab list, pre-filled with current United States salaried brackets, with a Custom option. The same slabs feed the salary calculator, so changes stay consistent across tools.

Income tax calculator

Inputs: country, year, income, and filing type. Outputs: annual tax, monthly tax, effective rate, net income, and a slab table showing each bracket.

Budget split

Enter income and optional expenses. The 50/30/20 amounts appear in a CSS and SVG chart, with differences from your actual spending.

VAT, add or remove

Enter an amount and rate, then choose add or remove mode. Results show net amount, tax, and gross amount.

Salary net pay

Gross pay, slab tax, PF percentage, EOBI, custom deductions, and bonus. Monthly and annual net pay appear with a full breakdown.

Currency and prices

Rates, history, and living costs

Live rates come from open.er-api.com and are cached for one hour, with the last-updated time shown. Historical rates come from the ECB via Frankfurter, so unsupported currencies such as USD are flagged.

Inflation and cost of living use embedded, editable datasets. Each shows its source and date, and a selection without supported data says so rather than estimating.

Currency converter

Swap control, major currencies including USD, rates in both directions, and friendly messages when the feed is unavailable.

Historical and matrix

A 30-day SVG line chart for a chosen rate, and a 4 to 8 currency matrix with a highlighted diagonal and a Copy table control.

Inflation and living costs

Inflation shows amount, total change, and average yearly percentage from embedded CPI data. Cost of living scales salary by a target and current city index across 20 or more cities.

Investment and cash

Returns, loans, and cash counts

Percentage, compound growth, ROI, loan repayment, and cash counting, each with its formula and a clear table of results.

Loan and compound tables

The loan calculator applies EMI = P·r(1+r)^n/((1+r)^n−1), shows total interest and total payment, and includes an amortization table with CSV download. The compound calculator adds a yearly table and SVG chart.

Percentage tools

Four mini-calculators: X% of Y, X as a percent of Y, change, and difference.

ROI and margin

Cost, selling price, and extra costs produce profit, ROI, margin, and markup.

Loan schedule

EMI, total interest, total payment, and a month-by-month amortization table.

Cash counter

USD by default with other currencies, a greedy breakdown table, and a note-count total mode.
