Example Data Table

Wedding Cost Today	Months	Inflation	Current Savings	Monthly Saving	Return	Buffer
USD 20,000	18	4.00%	USD 2,000	USD 800	6.00%	10.00%
USD 35,000	24	5.00%	USD 5,000	USD 1,050	7.00%	12.00%
USD 15,000	12	3.00%	USD 1,500	USD 1,000	4.00%	8.00%

These examples show typical inputs. Your results depend on your own timeline and assumptions.

Formula Used

Inflation-adjusted goal: Goal_future = Goal_today × (1 + inflation)^(months/12)
Buffer target: Target = Goal_future × (1 + buffer)
Net annual return (approx.): r_net = (return − fee) × (1 − tax)
Monthly rate: r_m = (1 + r_net)^(1/12) − 1
Month-by-month balance: Balance = Balance × (1 + r_m) + deposit
Required monthly saving: Solved via binary search using the simulation.

The simulation supports a lump sum and annual growth in monthly saving (applied every 12 months).

FAQs

1) What does inflation do in this calculator?

Inflation increases your estimated cost over time. The calculator grows today’s budget to a future amount using your months and inflation input.

2) Why include a safety buffer?

A buffer protects against surprise expenses like vendor changes, travel, or price spikes. It adds a percentage on top of your inflation-adjusted target.

3) How are investment returns applied?

Returns are converted to a monthly rate and applied each month before deposits. This models steady compounding on your saved balance.

4) How does “Tax on Returns” work here?

It’s a simple approximation that reduces the annual return. Real taxes depend on account type, holding period, and local rules, so treat it as a planning estimate.

5) What does “Saving Growth per year” mean?

It increases your monthly saving once every 12 months. Use it if you expect salary growth or planned step-ups in contributions.

6) When is the lump sum added?

The lump sum is added at the end of the selected month in the simulation. Pick the month you expect a bonus, gift, or refund.

7) What is the difference between Projection and Required mode?

Projection shows where you land using your monthly saving. Required mode calculates a monthly saving needed to hit the target plus buffer, given your assumptions.

8) How should I choose the return rate?

Use a conservative figure based on your saving vehicle. Cash accounts may be lower, while investments vary. If unsure, test multiple rates and compare the gap.
