|---|---|---|---|
| $15k · 10% · 5-year | $318.71 | $4,122.34 | $19,122.34 |
| $8k · 12% · 3-year | $265.71 | $1,565.72 | $9,565.72 |
| $30k · 8.5% · 7-year | $475.09 | $9,907.94 | $39,907.94 |
| $5k · 18% · 2-year | $249.62 | $990.89 | $5,990.89 |
How This Calculator Works
Enter the amount you want to finance, the APR you have been quoted, and the term. The calculator turns the APR into one constant monthly payment using the amortization formula and shows total interest paid across the loan.
The Formula
Fixed-Rate Amortization
P = loan amount, r = monthly rate (APR ÷ 12), n = number of monthly payments
Worked Example
Financing $15,000 of wedding spend at 10% APR over 5 years gives a monthly payment of about $319. Total repayments come to roughly $19,120, so interest adds about $4,120 — money that does not go to the wedding itself.
Key Insight
Wedding loans almost always cost more than the savings approach the calculator's sibling tool models. A $15,000 wedding saved for over two years on a 2% account costs effectively nothing in interest; financed at 10% over five years it adds $4,000+. If the date allows, even partial saving cuts the loan needed.
Frequently Asked Questions
What is a wedding loan?
An unsecured personal loan used to pay wedding costs. Rate and limit depend on credit profile rather than collateral. Most lenders simply market a standard personal loan under a wedding-specific name.
Is a wedding loan a good idea?
Usually a last resort. The math nearly always favors saving where the timeline allows. Credit-card promotional 0% offers can compete on short terms, but only if you can clear them before the rate jumps.
What rate should I expect?
Unsecured personal loans typically run 8% to 24% APR depending on credit. The strongest credit profiles see the lowest end; subprime borrowers can hit the cap or be declined outright.
Should I borrow or use savings?
Use savings first if you have them. Financing turns wedding spend into multi-year debt that competes with home, baby, and retirement goals. If the choice is wedding-loan-or-postpone, the math says postpone.
What if the wedding costs more than planned?
Add the overrun to your loan amount and re-run the calculator. Most weddings come in over budget; honest planning includes a 10% to 20% contingency in the financed figure.

Methodology & Review
Payments use the standard fixed-rate amortization formula. Wedding loans are unsecured personal loans, so rates depend on credit profile rather than collateral. The calculator assumes a fixed APR on the full term.
