How much you need to retire in Montana

The 4% rule is a widely used starting point: multiply the annual spending your savings must cover by 25 to get a target nest egg. In Montana, typical retiree costs run about $35,720 a year; after an expected Social Security benefit, the savings you need to generate the rest comes to roughly $343,000.

The calculator then projects your current savings and monthly contributions forward at a 5% real return to show whether you're on track or facing a gap. One caveat for Montana: state taxes on retirement income are not yet built in, and they can shift the picture — so treat the result as a planning baseline.

A quick gut check for Montana: covering about $35,720 a year, minus an expected Social Security benefit, implies roughly $343,000 invested under the 4% rule. Retiring earlier, spending more, or assuming a lower return all raise that target, while a paid-off home or a larger Social Security benefit lowers it — the calculator lets you watch each lever move the number.

The biggest swing factor is when you start. Because returns compound, the same monthly contribution invested in your thirties can end up worth far more at retirement than one started in your forties, even in the same Montana scenario. If the projection shows a gap, raising the monthly contribution a little now is usually more powerful than trying to make it up later with larger amounts closer to retirement.
