By life stage

The decisions that quietly shape a decade.

Six life moments, mapped to the calculators that actually move the needle in each.

Buying a home

Underwrite the biggest line item of your life.

Affordability, prepayment, and rent-vs-buy: model the loan before the broker calls back.

Paying off debt

Pick a payoff order and feel the runway shorten.

Snowball, avalanche, balance transfers: the fastest path out of a balance.

Growing wealth

Compounding does the work. You set the inputs.

SIPs, ETFs, dividends: model the curve before you commit a single rupee or dollar.

Planning retirement

The single date that quietly drives every decision.

FIRE, 4% rule, Roth, 401(k): sketch the long arc and read the contributions backwards.

Filing taxes

Clean answers to the questions CAs charge for.

Federal, state, capital gains, refund: see your real number before you sign.

Running a business

Price products and read P&Ls like an operator.

Margin, pricing, cash flow, burn: the numbers that decide whether you survive.
