How much does cutting my annual expenses by $5,000 lower my FIRE number?
At a 4% withdrawal rate, every recurring dollar of annual spending you eliminate reduces your target by 25 dollars, so cutting $5,000 a year lowers your FIRE number by about $125,000. At a more conservative 3.5% rate, the same $5,000 cut trims roughly $143,000 off your goal.
This leverage is why frugality is so potent in FIRE: a permanent expense reduction shrinks the finish line and boosts your savings rate at the same time. It works best on recurring costs like subscriptions, insurance premiums, housing, and interest, rather than one-time purchases. Before assuming you must earn more, look for durable spending cuts, since each one does the work of tens of thousands in extra savings. Find candidates with wealthserene.com/tools/budget-analyzer.
