## About FIRE Calculator

FIRE Calculator is a free web tool for planning financial independence and early retirement. Enter monthly retirement expenses, your invested portfolio, monthly contributions and assumptions for returns and inflation to estimate a FIRE number: annual expenses divided by a chosen withdrawal rate, adjusted for inflation up to your target age.

An optional Monte Carlo simulation runs random market paths with varying returns and withdrawals, showing percentile charts and a downloadable CSV. The planner also estimates a financial independence age and the starting monthly investment needed. Users can pick one of 25 currencies.

It suits people comparing early retirement scenarios and withdrawal rates such as 3%, 3.5% and 4%. Taxes, fees, pensions and local account rules are not modelled, so results are planning estimates, not guarantees.

## About Incusia

Incusia is an invoicing tool for freelancers and small businesses. It lets you create invoices and estimates, send them by email, and accept card, Apple Pay and bank payments. You can see whether an invoice was delivered, opened or paid.

Automatic payment reminders go out on a schedule. The Pro plan adds recurring invoices, late fee calculations, deposits and payment plans, time tracking that feeds into invoices, receipt scanning, and a client portal where clients can view and pay without logging in. The site also tracks how many days each client takes to pay.

Starter costs $9 a month and Pro costs $29 a month, with a one-time $99 Lifetime option. Every plan includes a 7 day free trial with no card needed. The site says the price a customer signs up at is locked in its Terms of Service. There is no free plan.
