How It Works
Payback (months) = Investment / Monthly Savings. Shorter is less risky because you recover cash sooner. The weakness: it ignores savings after payback and the time value of money. For that, use NPV. Still, payback is the fast first filter most small businesses actually use.
What Should You Do?
Scenario 1: a $5k investment saving $500/month pays back in 10 months — low risk. Scenario 2: a $50k machine saving $1k/month takes 50 months — question it with NPV. Scenario 3: seasonal savings should be annualized, not naive monthly.
Frequently Asked Questions
Payback vs NPV?
Payback is quick and risk-focused but ignores post-payback value and time value; NPV is comprehensive.
What payback is acceptable?
Shorter is safer; many small businesses target under 2 years for equipment.
Do I include financing?
This is cash basis; if financed, the monthly 'savings' should net out the loan payment.
