Methodology
The calculator projects your current savings forward and solves for the recurring contribution needed to reach the target.
- Current savings is grown over the selected horizon at the provided annual rate.
- Recurring deposits are applied at the selected contribution frequency.
- The required contribution is solved iteratively to reach at least the target amount.
- Contribution timing is end-of-period.
Using This Tool Well
When to use this tool
- Deadline funding plan: a $50,000 target with $5,000 saved over five years at 5% needs about $640.87 per month in the current model.
- Conservative-return check: rerun the same goal at 0%, 3%, and 5% so the monthly contribution is not dependent on one optimistic return assumption.
- Target-date negotiation: test whether moving a goal from 36 months to 60 months lowers the recurring contribution enough to fit the household budget.
How to read the result
The required contribution is the recurring deposit that reaches the target on the smooth path. If the money is needed soon, read the result as a minimum planning number and compare it with a conservative-return version before you trust the target date.
Common mistakes
- Letting optimism fund the gap: the same $50,000 five-year goal needs $750 per month at 0% versus about $641 at 5%, so the return assumption is worth roughly $109 per month.
- Confusing cadence: $640.87 per month is not $640.87 per year, and using the monthly answer annually would underfund the plan by more than $7,000 per year.
- Forgetting account friction: a 1% fee, taxes, withdrawal rules, and inflation can turn a contribution that barely works in the model into a shortfall near the deadline.

Premises and Limitations
- Returns are assumed constant over the full horizon.
- Recurring contributions are modeled as fixed deposits at the selected frequency.
- Taxes, account fees, inflation, and variable market returns are not included.
FAQ
What if I already have part of the goal saved?
Current savings is included in the projection before required recurring contributions are solved.
Does this assume a guaranteed return?
No. It models a constant return rate for planning, but real returns can vary.
Can I use monthly or yearly savings?
Yes. You can choose contribution frequency and the required contribution will be shown in that cadence.
