How This Calculator Works
Enter the amount you want saved, the rate a savings account pays, and how long until you want to be ready. The calculator solves for the monthly contribution that reaches the target, with the small interest earned shown separately.
The Formula
Required Monthly Saving (Sinking Fund)
FV = goal amount, r = monthly rate (annual ÷ 12), n = number of months
Worked Example
Saving a $10,000 buffer over one year at a 2.5% savings rate needs about $824 a month. Almost all of it is your own deposits; over a single year, interest adds little more than a hundred dollars.
Key Insight
A baby's first-year costs come in waves — medical bills, gear, and a possible dip in income from leave. A cash buffer in place before the due date turns those waves into planned expenses rather than emergencies.
Frequently Asked Questions
What should the savings target cover?
Medical and delivery costs, baby gear, ongoing supplies, and a cushion for any reduction in income during parental leave. Tailor it to your situation.
How much does a baby's first year cost?
It varies widely with healthcare, childcare, and lifestyle choices. Build the target from your own expected costs rather than a single national figure.
Should I also plan for lost income?
Yes. If parental leave is unpaid or partly paid, include the income gap in the target so the buffer covers both new costs and reduced pay.
Where should I keep the savings?
A separate high-yield savings account keeps the fund accessible for the irregular timing of baby costs and earns a little interest meanwhile.
Is this the same as a college fund?
No. This is a short-term buffer for the arrival and first year. Saving for education is a separate, much longer goal better suited to a 529 plan.

Methodology & Review
The required monthly contribution solves the future-value-of-an-annuity formula for the payment that reaches the target. Over a short horizon the interest earned is small.
