Savings Goal
How to Use This Savings Goal Calculator
This calculator solves the savings-goal triangle: given any two of target amount, monthly contribution, and timeline, it calculates the third — showing exactly what it takes to hit a specific number by a specific date.
How It’s Calculated
Monthly Contribution = Goal / [ ((1 + r)^n − 1) / r ]
The same equation is solved algebraically for whichever variable is missing — contribution, time, or final amount.
Example
Reaching a $20,000 goal in three years with a 4% return requires saving about $515 per month — or saving $400 per month instead stretches the timeline to roughly four years.
Frequently Asked Questions
Should I include investment returns in my savings goal timeline?
Only if the money is actually invested. For short-term goals under two to three years kept in cash or savings accounts, using 0% or a conservative high-interest savings rate is more realistic.
What if I can’t afford the required monthly contribution?
The tool can solve for a longer timeline at a lower monthly amount instead. Extending the timeframe is often the easiest lever to adjust.
Does inflation affect my savings goal?
Yes — a fixed dollar goal loses purchasing power over time, so longer-term goals should ideally be set in today’s dollars and adjusted upward for expected inflation.
