how to matcha sum value with bunch of numbers

You can “match a sum value with a bunch of numbers” by finding which numbers in your list add up to a target. In Excel, the most common ways are:

1. Use Solver (built-in, good for one solution)
2. Use a custom function / VBA (to find all combinations)
3. Use an add‑in like SumMatch (simpler UI, no Solver needed)

Below is a practical, step‑by‑step approach using Excel.

Quick overview: what you’re solving

You have:

• A list of numbers (e.g. invoices, amounts):
  A2:A10 = 919, 1272, 629, 2000, 500, ...

• A target sum (e.g. payment to match):
  C1 = 2820

You want to find which subset of A2:A10 adds up to C1. Mathematically, this is the subset sum problem ; Excel can solve small cases well.

Method 1: Excel Solver (recommended for most users)

Step 1: Prepare your sheet

Assume:

• Numbers in A2:A10
• Target sum in C1

Add a binary selector column in B2:B10:

• These will be 0 or 1 to indicate whether each number is included.

In B2 type: 0
Copy down to B10. In C2 (calculated sum of selected numbers):

excel

=SUMPRODUCT(A2:A10, B2:B10)

In C3 (difference from target):

excel

=C2 - C1

We want C3 to be 0.

Step 2: Enable Solver

If you don’t see Solver:

1. Go to File > Options > Add‑Ins.
2. At the bottom, choose Excel Add‑ins , click Go.
3. Check Solver Add‑in , click OK.

Now Solver is under Data > Solver.

Step 3: Set up Solver

1. Click Data > Solver.
2. Set:
   • Set Objective : C3
   • To : Value Of: → 0
   • By Changing Variable Cells : B2:B10
3. Add constraints:
   • Click Add
   • Cell Reference: B2:B10
   • Constraint: bin (binary)
   • Click OK
4. Choose solving method:
   • For simple 0/1 problems, Simplex LP or GRG Nonlinear works.
5. Click Solve.

Solver will set some B cells to 1 and others to 0. The numbers with 1 in column B are the ones that match your target sum.

Method 2: Find all combinations (VBA or custom function)

If you need every possible combination that equals the target, Solver gives only one solution per run. You can:

• Write a VBA macro that loops through combinations and records matches.
• Or use an existing add‑in like SumMatch that does this automatically.

Basic idea of a VBA approach:

• Loop through all subsets of your list.
• For each subset, compute the sum.
• If sum == target, store that subset.

This is more advanced; if you want, I can give you a ready‑to‑paste VBA module.

Method 3: SumMatch add‑in (no Solver)

SumMatch is an Excel add‑in specifically for this:

1. Install SumMatch from: https://summatch.net/
2. Load your list of numbers and the target sum.
3. Run it; it returns all combinations that match the target.

This is often easier if you’re reconciling many payments or invoices.

Example: concrete numbers

Suppose:

• A2:A5 = 919, 1272, 629, 2000
• Target = 2820

Using Solver:

• It may set:
  • B2 = 1 (919)
  • B3 = 1 (1272)
  • B4 = 1 (629)
  • B5 = 0 (2000)

Then:

excel

919 + 1272 + 629 = 2820

And C3 (difference) becomes 0.

Tips to avoid common issues

• Decimal rounding : If your numbers have many decimals, Excel might treat 4.32 as 4.3199999999. Use ROUND or set a small tolerance in tools like SumMatch.
• Large lists : With many items (e.g. 100+), the problem becomes harder; Solver may take longer or not find a solution.
• Multiple solutions : If there are many combinations, Solver finds one; use VBA or SumMatch to get all.

If you tell me:

• How many numbers you have, and
• Whether you need just one match or all possible matches,

I can give you a tailored formula or a small VBA script you can paste directly into Excel. Information gathered from public forums or data available on the internet and portrayed here.
