MACH RUN

Engine

The Hale sample starts with two paychecks, three kids, and a $2,500,000 nest-egg goal. With MACH RUN, they iterate and build a household that is on track for more than $2,500,000, with their money lasting at least through age 95.

Households that plan for retirement end up with roughly three times the wealth of those that don't (Lusardi & Mitchell, NBER Working Paper 17078, 2011).

For military and veteran households

MACH RUN blends them with the rest of the household, and with nominal rates of returns, the Monte Carlo engine, and a few moments of your time, shows what that mix can pay in retirement.

MACH RUN can also estimate what your military retired pay and VA are worth today — the lump sum a zero-risk annuity would need to pay the same checks.

Tap a payment above. Tap it again, or tap outside the cards, to return to the sample. Military retired pay and VA show the zero-risk annuity at age 50. TSP shows the balance at the required-withdrawal age, 75.

Built by a fighter pilot who needed it.

Matthew "Cain" Olde flew F-15s for the U.S. Air Force and retired into the same problem every military household has: active duty, guard/reserve, or retired pay, VA, TSP, a spouse's paycheck, and Social Security all land in different places, and nothing shows them together. His father was a USAF fighter pilot who became a Certified Financial Planner, so he grew up with a love of fighter jets and personal finances. MACH RUN is the tool Matt wished existed, built after he hung up the G-suit.

Change the savings rate and contributions.

Watch that date and FIRE number move.

Test if your money lasts across 1,000 futures (Individual Unlimited).

Sample, from the pre-filled demo. Not your plan.

In 100 of 100 futures like this one, your money lasts through your longevity age (95).

Spreadsheets take time you'll never get back, and FIRECalc isn't built for TSP, military, and veterans. MACH RUN saves that time and is built for those paychecks. Use the fighter pilot's OODA Loop to inform your financial path quickly and efficiently, giving you time back. Monte Carlo is on Individual Unlimited.
