How This Calculator Works
Enter the wedding budget, the rate a savings account pays, and how long until the date. The calculator solves for the monthly contribution that reaches the budget, with the modest 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 for a $28,000 wedding two years out at a 3% savings rate needs about $1,133 a month. Deposits cover roughly $27,200 of it; over such a short horizon, interest adds only a few hundred dollars.
Key Insight
For a goal this close, the monthly habit does nearly all the work — the rate barely matters. Paying for a wedding from savings rather than credit avoids interest that can shadow a marriage for years.

Frequently Asked Questions
What should the wedding budget include?
Venue, catering, attire, photography, flowers, rings, and a contingency. A complete budget keeps the monthly savings target realistic.
Why is the interest so small?
Wedding savings sit in cash for a short time, so they earn little. Almost the entire budget comes from your monthly deposits.
Should we save or borrow for a wedding?
Saving avoids interest and starts the marriage debt-free. Borrowing brings the date forward but adds a cost that outlasts the day itself.
What if the budget changes?
Wedding costs often drift upward. Revisit the figure as plans firm up, and adjust the monthly contribution or the date if the budget rises.
Where should we keep the savings?
A separate high-yield savings account works well — it keeps the fund visible, earns a little interest, and makes it harder to spend by accident.
When is this calculator unreliable?
Less reliable when wedding costs vary substantially by region (Manhattan $80K+ vs Mississippi $15K), when inflation 2022-2024 substantial (+20-30% wedding costs), when family contributions / parents substantial variance, when wedding scope changes mid-planning (substantial), or when tax-advantaged accounts assumed but not optimal short horizon (HYSA 4-5% preferred for <3 year horizon).

Wedding savings = target wedding budget × allocation per month × (1 + r)^n. Calculator returns required monthly savings to reach goal by date. U.S. average wedding 2024 (The Knot): ~$33,000; metro premium $40K-$80K+. High-yield savings 4-5% 2024. Substantial guest count + venue tier drives cost. RELIABILITY: Reliable for documented savings horizon + return assumption. Less reliable when (a) wedding costs vary substantially by region (Manhattan $80K+ vs Mississippi $15K), (b) inflation 2022-2024 substantial wedding costs +20-30%, (c) family contributions / parents (substantial variance), (d) wedding scope changes mid-planning, (e) tax-advantaged accounts not optimal short horizon (HYSA preferred).
