Wedding Savings Calculator: How Much to Save Each Month
Enter your wedding budget, what you've already saved, months until the big day, and your savings account APY. The calculator shows the exact monthly deposit that will hit your number — and how much interest your savings account is earning you along the way.
Build the savings plan before you sign any contract
Most couples do this backwards: book the venue, swipe the deposit, then work out the savings math later. By the time "later" comes, you're already committed to $8,000 you haven't earned yet. Run the math first. Use the Wedding Budget Calculator to get your target number, then plug it in here to see the monthly savings reality.
The HYSA rule: don't leave money on the table
In 2026, high-yield savings accounts at Ally, Wealthfront, Marcus by Goldman Sachs, and SoFi are paying 4.0-4.75% APY. Your "regular" bank checking or savings account is probably paying 0.01% APY. If you're saving $1,500/month for 14 months toward a wedding, that's the difference between:
- Big-bank savings (0.01%): $21,001 balance at the wedding
- HYSA at 4.5% APY: $21,610 balance at the wedding
That's $609 extra — for literally no additional effort. $609 buys a nice upgrade on your photography package. Use it.
How to pick the wedding HYSA
- No fees. Full stop. Any fee kills the math.
- FDIC-insured. All major online banks are — verify before transferring.
- 2-4 day transfer window. You'll move money in for savings and out for vendor payments. Faster is better.
- Label it "wedding." Seriously. Most HYSAs let you nickname accounts. Seeing "wedding: $18,200" every time you log in builds commitment.
Open a second sub-account labeled "honeymoon" and one labeled "wedding buffer." Three buckets keep the accounting simple when unexpected costs hit.
How to actually save the monthly number
Pay yourself first (automate it)
Set up an automatic transfer from your paycheck (or the day after payday) directly into the wedding HYSA. The amount the calculator gives you. Day one. Do not wait until end-of-month to see "what's left over" — nothing will be left over.
Use a second credit card for wedding spending
Open a dedicated travel or cashback card 4-6 months before wedding spending really ramps (deposits on venue, photographer, dress). Hit the signup bonus through routine wedding payments. Most cards offer $500-$1,000 in points for $3,000-$6,000 of spend — money you're already spending. Use the points for the honeymoon.
Track monthly, not daily
Checking your balance every day causes anxiety and no extra progress. Check monthly on a specific date ("the 5th of every month") and compare against the calculator's projected balance. If you're ahead, breathe. If you're behind, adjust one line item now — not the whole plan.
What to cut to hit the number
If the calculator spits out a monthly savings number you can't make on current income, you have four levers:
- Extend the timeline. Moving the wedding from 14 months out to 18 months reduces monthly savings by 20-25%. No other lever has that much impact.
- Shrink the budget. Every $5,000 off the top saves ~$350/month at a 14-month timeline.
- Add income. Side work, freelance, selling things. Hardest path but sometimes necessary.
- Parental contribution. If parents on either side are considering a contribution, this is the conversation to have early — not at month 3 when you're panicking.
The hidden cost of deposit timing
Your savings curve is not smooth. Deposits spike at specific moments: venue at booking (usually 50% of venue fee, so $4,000-$9,000 in one check), caterer deposit (25-40% at booking), photographer deposit (30-50%), final balances at T-minus-30 days for most vendors.
That means your HYSA balance needs to be significantly ahead of monthly-average through months 10-3 of the engagement, because you'll be making big payments along the way. Plan for this by front-loading your savings in the first 4 months if you can — save $2,500/month for the first four months, then drop to $1,200/month once the big deposits are out the door.
Wedding loans vs. HYSA financing
Don't. Wedding loans (Upstart, SoFi, LightStream) run 9-18% APR in 2026. HYSAs pay you 4.5% to save. Taking a $15,000 wedding loan at 11% APR costs you $1,650 in interest in year one — and that's money that should go to the down payment on a house.
The math is clear: finance the wedding with savings, even if it means scaling back. A smaller wedding with zero debt is objectively better than the "wedding of your dreams" with $20K in debt at 12% APR hanging over the first year of marriage.
What to do with leftover wedding savings
Most couples end up 3-8% under budget if they track carefully. Three options for the surplus:
- Upgrade the honeymoon — see the Honeymoon Calculator.
- Move it into the joint "house down payment" or "emergency" fund immediately.
- Keep it in the wedding account for 90 days — unexpected costs nearly always appear (photographer reprints, dress preservation, one more tip envelope).
Export the plan, commit to it
Download the PDF, print it, put it somewhere you see weekly (fridge, bathroom mirror, desk). Commitment devices matter. A saved digital file is aspirational; a printed plan on the fridge is real.
