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.

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