Theory behind the calculation
The calculator walks forward one contribution period at a time. Each period begins with the previous balance, grows by the per-period interest rate, then adds your contribution for that cycle. Matching compounding to your contribution frequency keeps the projection aligned with your real cash flow. Reverse mode instead works backward from your target date to calculate the required regular contribution.
Core formula
Balance_next = Balance_current × (1 + r/n) + Contribution, where r is annual return, n is periods per year, and the contribution reflects any scheduled annual increases.
Inflation & compounding
If inflation is enabled, each period’s ending balance is deflated to show its purchasing power in “today’s dollars.” Compounding can be set to match contributions or use fixed monthly, quarterly, or yearly compounding.
Why this calculator still matters
Most savings goals start as guesses. This calculator turns that guess into a timeline you can follow. By seeing how contributions, returns, and inflation interact over time, you can adjust early—before your goal drifts off track.

Frequently Asked Questions
How accurate is this calculator?
Accuracy depends on how close your assumptions (returns, inflation, contributions) match reality. The math itself is exact for your inputs.
Does inflation really affect long-term savings?
Yes. Inflation reduces purchasing power, and even low inflation compounds over time. Turning on the inflation toggle helps you see the real value of your savings.
What contribution frequency should I choose?
Match your deposit schedule: monthly for salaries, weekly/biweekly if you’re paid more often, quarterly/yearly for lump-sum savers.
Why is the timeline different from other calculators?
This tool simulates every period with your settings so the journey stays transparent rather than just showing the end result.
Can I use this for retirement planning?
Absolutely—plug in your retirement target, contributions, and returns to see the same period-by-period clarity.
Does the calculator store any of my data?
No. Everything runs 100% in your browser. Nothing is saved, shared, or sent anywhere.
