NestFIRE answers the one retirement question that matters: will I have enough, and when?
Most apps show you what you spent. NestFIRE shows you what it means — projecting your spending, income, savings and investments forward, year by year, to reveal your financial independence (FIRE) date.
A FIRE CALCULATOR THAT KEEPS PLANNING
Most FIRE calculators give you one number and stop. NestFIRE is a retirement planner that keeps working: set your current age and target retirement age, and the forecast builds a year-by-year cash flow from today to age 95, inflation-adjusted, scoring whether your plan is actually funded.
EXPENSE TRACKER AND INCOME PLANNER
Log expenses and income in seconds by category. Set a monthly budget and see actual versus planned at a glance. Map every income stream — salary, pension, rental income, dividends — with a start and end age, so your projection reflects real life instead of a flat average.
NET WORTH TRACKER
Add savings accounts, investments, ETFs, bonds and property. Each asset compounds at its own growth rate. Configure a monthly drawdown from any asset and NestFIRE turns it into an income stream in your forecast, warning you if the balance would run out early.
YOUR CURRENCY, YOUR NUMBERS
NestFIRE detects your currency from your device and formats every figure to it — dollars, pounds, euros, yen and more. Change it anytime in Settings. No conversion, no confusion.

PRIVACY BY DESIGN

IMPORTANT
NestFIRE is a personal finance planning tool. It is not a licensed financial adviser and does not provide financial, investment, or tax advice. All projections are mathematical estimates based on the information you enter and the assumptions you choose. Actual results will differ. Always consult a qualified, licensed financial professional before making financial decisions.
